CEMS WORKSHOP
11 am to 12 pm (EST)
Teledyne API CEMS TRAINING WORKSHOP
This presentation will cover the new TAPI N-Series platform. This will include changes in the architecture of the instruments and comparisons between it and our previous generation T-Series platform. The session will be a mix of PowerPoint and live feeds where it will showcase the hardware of the N100 SO2 analyzer using multiple cameras. It will cover the specific parts of the instruments that relate to the CEMs marker such as ease of maintenance, troubleshooting, and operation. This will be a sales presentation but will have the good information that folks attending would expect to learn.
Bryan will also present a second presentation later on Chemiluminescence NOx analyzers work by detecting the light emitted when Nitric Oxide (NO) reacts with ozone (O3). In order to measure Nitrogen Dioxide (NO2) by chemiluminescence, the sample must first be converted to NO. Two common methods for the conversion of NO2 to NO are heated stainless-steel and molybdenum converters. Either converter type has pros and cons and will be chosen based on the monitoring application to maximize performance and operation. This discussion will focus on how to select the proper converter for your application, along with maintenance and efficiency expectations.
Co-Authors: Doug Haugen, Tim Morphy, Patrick King, Jesse Mendoza; Teledyne-API
QUESTIONS
1. What is the expected lifespan of a molybenum or stainless steel converter in a NOx analyzer.
2. How does the choice of converter affect interferents in the measurement.
3. What applications are there for each type of converter.

B2.2 CFB Baghouse Optimization given the Use of Gore Membrane Filter Technology Advancements
(1:50 PM – 2:10 PM EST)
B2.2 CFB Baghouse Optimization given the Use of Gore Membrane Filter Technology Advancements
Each Coal Fired Power plant comes with its own set of unique challenges. Plant operators are constantly balancing output requirements with a never-ending list of ongoing maintenance. Equally as important, these demands need to be balanced with environmental compliance, energy consumption and overall plant profitability. This paper will highlight real time data logged from a Lignite based coal fired power plant and how a simple change in filter bags is allowing for a significant increase in total airflow. Additional details will be shared how this resulting lower membrane filter resistance can be optimized to allow for lower pressure drop, less cleaning, longer effective bag life, higher airflow and less sorbent injection usage . . . and how the use of optical data logging sensors provided for the remote collection of this data through the use of a specialized cloud based technology. This plant’s desire to improve the Total Cost of Ownership of operating their main baghouse led them to this new technology and the data presented in this paper is the foundation of this decision making.

B2.3 Multi-gas FTIR Monitoring in Carbon Capture and Storage
(2:10 PM – 2:30 PM EST)
B2.3 Multi-gas FTIR Monitoring in Carbon Capture and Storage
Carbon capture plants deploy several methods ranging from membranes, to amine-based technologies that involve components which degrade into ammonia, formamide, aldehydes, organic acids, nitrosamines and other toxic gaseous species. Gas products pose challenges for sampling and analysis given the presence of water vapor and high concentrations of carbon dioxide as well as certain water-soluble compounds.
There are currently stationary and semi-portable hot-wet FTIR (Fourier Transform Infrared Spectroscopy) instruments for online analysis and gas emissions monitoring from such plants. These units scan a wide wavenumber spectrum where several species absorb infrared light, allowing to simultaneously measure more than 25 gases. FTIR analytes include standard criteria pollutants such as CH4, CO2, NOx, SO2, acid gases, NH3, aldehydes, and other VOCs, and extend to amines and amine by-products observed in CO2 absorber and amine stripping towers. Some of these substances are ecotoxic, have low biodegradability, and are known to cause cancer.
This presentation reviews FTIR principles, sampling solutions, and available configurations for online gas analysis at carbon capture and storage plants. It highlights industrial and laboratory scale case studies using semi-portable and CEM systems, and advantages as related to analytical performance, component flexibility, and maintenance requirements.
Co-Author: Jim Cornish, Gasmet Technologies
QUESTIONS
1. How are different gas matrices and concentrations analyzed?
2. What gas components cannot be monitored with FTIR?
3. Can I measure from multiple sampling points within a plant?
B2.4 CEM Sample Systems
(2:30 PM – 2:50 PM EST)
B2.4 CEM Sample Systems
CEM Sample Systems are often overlooked or given the least amount of attention in the design of a Gas Analysis System. But arguably it is the most important engineered segment of any Gas Analysis System.
As happens often, those responsible for designing and packaging a Continuous Emissions Monitoring System overlook the small details that will make or break a CEMS Performance.
And those that maintain these systems for the most part inherit what they have, were not part of the initial design and often times ask themselves, “there’s got to be a better way!”.
Getting a representative sample, transporting it to the analyzer enclosure and conditioning it without removing the required measured analytes is not a one size fits all approach.
This discussion will touch on the considerations for the Sample Conditioning and Transport segment for a CEMS Sample System both during initial design and post installation enhancements.
B2.5Digitizing Visual Emission Observations — Bringing Opacity into the Digital Age
(2:50 PM – 3:10 PM EST)
B2.5 Digitizing Visual Emission Observations --- Bringing Opacity into the Digital Age
Visible Emissions Observations are a subjective decision-making process. Typical requirements for the various Methods all require paper documentation of the observations to be created by observers. There is now the ability to create a digital record and the systems to automate these processes are being created. Compliance Assurance Associates, Inc. has created the VEO-APP to provide a digital documentation of observations and is in the process of marrying this technology with the Digital Opacity Measurement system – (a program to Analyze a Photo of the emission point) created by Mark Rood’s team at the University of Illinois Urbana Campus. What is the current state of the Art for this Technology?
Co-Author: Mark Rood
QUESTIONS
1. What will this hold for the future of Visible Emission Training and Certification?
2. Is the Technology able to separate Water Vapor Emissions and “see” opacity where water vapoir now blocks the observation of the emission?
3. When will the Digital Camera system be operational for BETA testing?
4. Will Cameras replace opacity observers in the near future?

B3.1 What is a Digital Transformation and How Do I Get Started?
(4:00 pm – 4:20 pm EST)
B3.1 What is a Digital Transformation and How Do I Get Started?
This presentation will discuss digitization of assets and preparing to scale for increased Return On DIGITAL Investment (RODI). The focus will be on ensuring successful use of digital deliverables with a digital handover. We will cover examples showing how your teams can attain increased accuracy, efficiency & engagement by working in a digital environmental. While there are many immediate benefits of digitization, your RODI will continue to rise as the digital deliverables are used beyond engineering. Your digital deliverables become living assets to be used on future projects and across the organization’s various departments. Over time, you will begin to build a digital asset library and recognize a true RODI. The key takeaway is that digital transformation is a process and to be successful, it is critical to get started. The companies that have successfully initiated this transformation get buy-in from stakeholders, plan for the big picture and take small steps to get there.

B3.2 Driving Improvements in Air Emissions and Permit Management with Digital Transformation
(4:20 pm – 4:40 pm EST)
B3.2 Driving Improvements in Air Emissions and Permit Management with Digital Transformation
Environmental professionals manage thousands of tasks and data points to manage air emissions and stay in compliance with Title V permits. Like many organizations, utilities are realizing the power of technology to collect, track, measure, analyze, and leverage data – including increased efficiency, fewer violations and improved visibility into compliance status.
Join this session to learn how utility companies use technology to answer the top questions often asked by management and operations:
– What is the fuel mix range we can use to stay under our permit limits?
– What is the maximum production output we can achieve based on permitted equipment?
– Do we need to buy or can we sell NOx/Sox/Carbon credits?
QUESTIONS
1. What concrete ways can air emissions software help me save money and manage my emission credits?
2. How do I convince operations to adopt technology?
3. How can I reduce data collection errors when managing air emissions?
B3.3 New Carbon-in-Ash Monitor to Increase Accuracy and Reliability at Industrial Plants
(4:40 pm – 5 pm EST)
B3.3 New Carbon-in-ash Monitor to Increase Accuracy and Reliability at Industrial Plants
The proper measurement of carbon-in-ash in coal plants is critical to optimize the boiler operation as this parameter has direct effect on NOx generation and efficiency of the unit. Also it is important for the quality control of the ashes when sold to the cement plants to produce clinker.
This process is normally made by manual sampling and lab analysis which typically requires several days. When conventional on-line analyzers are used (microwaves, infra-red, etc.), they have reported lack of accuracy and representativity when the operating conditions or fuel composition change over time.
INERCO´s monitor provides accurate measurements by automatically reproducing laboratory conditions, combining appropriate weight and calcination stages. The result is an innovative calibration-free technology that provides reliable results without interferences from the properties of coal or fly-ash and process conditions.
Co-Authors: Enrique Tova, Miguel Portilla, Miguel Delgado; INERCO
QUESTIONS
1. Does the calcination techniques described others application in industrial plants?
2. Does the system allow the use of several samplers? How many?
3. What are the typical maintenance considerations required by the system?
B3.4 Air Quality Modeling Options for Capped and Horizontal Stacks
(5:00 pm – 5:20 pm EST)
B4.1 Air Quality Modeling Options for Capped and Horizontal Stacks
The version of AERMOD released with the latest version of the Guideline added regulatory options for modeling capped and horizontal stacks using the POINTCAP and POINTHOR options. Material handling dust collectors, bin vent filters, and emergency generator engines are all source types that may have capped or horizontal stacks and with stack heights close to ground-level can be the driver for identifying compliant model scenarios. A case study comparing model concentration outputs using U.S. EPA’s previous point or capped source modeling guidance and the new POINTCAP and POINTHOR source types will be presented. Considerations for emission rates to use in modeling emergency engines will also be discussed.
B3.5 Dynamic Plume Modeling to Prepare & Respond to Chemical Emergencies
(5:20 pm – 5:40 pm EST)
B4.2 How to Use Dynamic Plume Modeling to Prepare for and Respond to a Chemical Emergency
There is an ammonia leak on your site – but you have no idea where it’s located. Your first priority is securing your facility and the community – but with the limited visibility you have, there is no way to know the full impact of the leak. Do you need to evacuate people? And if so, who? Will anyone in the greater community be impacted? These are likely questions that you will want to have answers to, and fast.
In this presentation, we will discuss dynamic plume modeling, the benefits that dynamic plume modeling, how to use modeling software and on site sensors to prepare for and manage a chemical emergency, and Create the most effective action plan so that you can protect your employees and the community.
QUESTIONS
1. What’s the difference between a dynamic plume model and a static plume model?
2. Can you give examples of how this would be used outside of emergency planning?
B3.6 Indoor Air Quality Modeling and Health Impacts
(5:40 pm – 6:00 pm EST)
B3.4 Indoor Air Quality Modeling and Health Impacts
A simulation of outdoor air quality and indoor in two buildings (office and housing) located in the centre of Madrid (Spain) has been run. The simulations are performed for the 2016 year. In indoor pollution simulations it is very important to model all the physical processes that affect concentrations, such as: emission, infiltration, deposition, mechanical and manual ventilation (closely related to the thermal comfort range of the building) and air exchange between rooms through the doors. The WRF/Chem atmospheric dispersion model is used to know outdoor pollution and meteorological conditions with high spatial (1 km) and temporal (1 hour) resolution and the energy model of the EnergyPlus building to simulate internal pollutants. The Generic Pollutant Model in EnergyPlus allows integrated modeling of multi-zone pollutants and dynamic thermal behavior within a single simulation package. From the concentrations, it has been estimated the exposure of several people who follow a predefined time pattern to pollutants to determine the health impacts of different internal emission sources. The impacts on the health of the emitting sources are greater in the warm months due to the operation of the air conditioning system. While the lowest impacts occur when air conditioning and heating do not work (transition days between hot and cold periods, March and October). The health impact of indoor emission sources is greater than outdoor pollution.

C1.1 Overview on Mercury Control Options for Coal-Burning Power Plants
(11 am – 11:20 am EST)
C1.1 Overview on Mercury Control Options for Coal-Burning Power Plants
With the USEPA issuing a national regulation requiring high levels of mercury capture, the need exists for low-cost removal techniques that can be applied to coal-burning power plants. The injection of powdered activated carbon into the ductwork upstream of the particulate control device is the most developed technology for mercury capture. Alternative techniques for mercury capture also play a role because of the numerous configurations of air pollution control devices present within the power plants, as well as the many different coals and coal-blends being burned. These methods employ sorbents, catalysts, scrubber liquors, flue gas or coal additives, combustion modification, flue gas cooling, barrier discharges, and ultraviolet radiation for the removal of mercury from flue gas streams. The DOE Mercury Program was an enormous success, spurring continuing development, demonstration, and commercialization of many technologies for the capture of mercury.
An overview of current and alternative technologies for mercury capture from coal-derived flue gas will be provided. In addition, six methods for mercury control within coal-derived flue and fuel gases have been recently developed at NETL and will be discussed. The on-going research needs for mercury control include improved sorbent-flue gas contact, development of poison-resistant sorbents and catalysts, novel sorbent promoters, new scrubber additives for retention of mercury within wet FGD systems, concrete-friendly activated carbons, new continuous measurement methods, benign coal additives, byproducts research, and exploration of international markets.

C1.2 Amended Silicate Products from Environmental Energy Services
The presentation will cover Amended Silicate products for mercury control in coal-fired power plants and other industrial sources, as well as products for catalytic destruction of organics . Environmental Energy Services (EES) now owns the rights to all Amended Silicate Technologies and products and has the manufacturing capability to produce these products for new customers. This includes four different Amended Silicate products for mercury control, AS-ULTRA for plants without scrubbers, AS-DryScrub for plants with dry scrubbers or CDS systems, and AS-HgOx and HgX-FGD for plants with wet FGD systems. In addition, products AS-DIOX and AS-TOTAL will be described, which are effective at mitigating dioxins, furans, PCBs, and other organics, acid gases, and trace semi-volatile metals, such as SO3, HCl, As, Se, Na, K, Pb, Cd, etc. Both full scale and laboratory performance data will be shown for these products, along with comparison to performance data from competitive products.
C1.3 Solutions, Not Just Sorbents
(11:40 am – 12 pm EST)
C1.3 Solutions, Not Just Sorbents
Choosing and purchasing sorbents is relatively simple; implementing a solution that works over the long term is much less simple. Hydrated lime dry sorbent injection (DSI) offers a means to reduce acid gas emissions; however, a holistic solution that works requires significant expertise and knowledge that goes far beyond sorbent-pollutant chemistry. Today, many utilities and industrial facilities operate with minimal engineering resources. Bringing a solutions-based approach can provide much-needed expertise to plant engineers to effectively operate systems and sorbents, and to have someone to call on when problems arise. Utilizing a sorbent supplier that provides multi-functional expertise can minimize total cost of ownership and alleviate material handling and compliance challenges. Over the past decade, DSI with hydrated lime has become commonplace for acid gas abatement (e.g. SO2, SO3, HCl, H2SO4, HF) and heavy metals abatement (e.g. arsenic, selenium) in industrial processes. Enhanced hydrated lime sorbents that are engineered to have higher pore volumes and surface areas are routinely applied to achieve high degrees (often in excess of 90% reduction) of acid gas and heavy metal removal rates in flue gas exhaust streams. In addition to hydrated lime properties, many other system parameters influence ultimate sorbent performance.

C1.4 Very Green Capture of CO2, NOx and SO2
(12 pm – 12:20 pm EST)
C1.4 Very Green Capture of CO2, NOx and SO2
PRDD has developed and verified through bench scale testing, a process that removes 99% CO2, 90%NOx & 99%SO2 ( target gases) from combustion and chemical process exhaust gas. • This proprietary technology for land and ocean vessel applications requires a small physical “footprint” and creates a very small carbon footprint. All three target gases are sequentially removed in a continuous mist phase reaction vessel not much larger in diameter than conventional duct for a given exhaust gas flow. • The combined CO2, NOx and SO2 abatement processes are collaborative. Chemical use is minimized because reaction products from one process are often reagents in another. • The primary consumable for all three processes is sodium chloride (table salt). The energy required to convert sodium chloride into other consumables is included in the energy balance shown below. • Most of the chemicals used in the CO2, NOx and SO2 capturing processes are recycled. All the reagent recycling only requires waste heat from combustion and nominal electrical power to operate pump etc. • The processes generate commercially viable effluent like sodium bicarbonate (baking soda). • The process is dramatically energy efficient. Because the chemical recycling is done with waste heat from combustion, a system sized for a large ocean-going vessel only requires 98 gallons of HFO/hour.
C1.5 Improving Hg Control While Reducing PAC Injection Rates
(12:20 pm – 12:40 pm EST)
C1.5 Improving Hg Control While Reducing PAC Injection Rates
PAC injection for controlling mercury emissions from combustion processes often has detrimental effects on other aspects of the process. Intelligent, non-traditional methods of performing multi-objective optimization which accounts for varying time constants and situation-specific prioritization of these objectives can realize improvements which traditional control is not capable of. Through the use of an adivarent control concept, mercury emission rate targets are met while also meeting stringent opacity targets and other emission rate limits. This system uses a combination of intelligent prioritization and data analysis and learning systems to achieve improved performance across all process objectives.
Co-Author: Brad Radl, Griffin Open Systems LLC.
QUESTIONS
1. What precludes this control methodology from being developed directly in the DCS?
2. If PAC and opacity are both improved as displayed, where’s the trade-off? There must be some other portion of the system or operations detrimentally affected?
3. How does the system account for other process disturbances (e.g. sootblowing)?

C2.1 Case Studies of Combustion Turbine Emissions Troubleshooting
(1 pm – 1:20 pm EST)
C2.1 Case Studies of Combustion Turbine Emissions Troubleshooting
Retirement of large coal units and demand for quick-start capabilities has facilities investing in natural gas combined cycle (NGCC) or existing machine upgrades. New NGCC facilities have large turbines, low turndown capabilities, and low permitted emissions. Turbine upgrades could increase power output, improve heat rate and dispatchability, or improve low-load cycling. Emission issues arise from larger combustion turbines requiring higher steam turbine power output. Low turndown and cycling capabilities have strained emissions control systems. This presentation will discuss design considerations for new and existing combustion turbines to meet emissions limits with a case study of actual industry lessons learned.

C2.2 On-Blade Gas Turbine Sensors for Real-Time Monitoring
(1:20 pm – 1:40 pm EST)
C2.2 On-Blade Gas Turbine Sensors for Real-Time Monitoring
Sensatek has developed and deployed 700°C+ wireless turbine blade metal temperature sensors. These sensors are bonded to blades to resist ultra-steep temperature shocks of 1,000°C per minute and g-loads in excess of 65,000g. The high temperature, low-to-zero drag antenna transceiver system can interrogate these passive RF sensors on time frames of just dozens of microseconds, enabling real time blade metal temperature in the hot gas path of modern turbines. With the Seliken materials system at the core of the Sensatek technology, wireless temperature sensing has been demonstrated up to 1,700°C.

C2.3 Reducing the Cost of Electricity Production: A Case Study
(1:40 pm – 2 pm EST)
C2.3 Reducing the Cost of Electricity Production: A Case Study
Normally when the steam based plants were designed , they have efficiency of 41-42%. However, after few years of operation, the annual efficiencies of some 20-30 year old plants falls in the range of 30-37% depending upon how good the operation and maintenance is done by the asset owners. The drop in efficiency and increase in maintenance cost causes enormous financial burden to the extent that the plants are forced to retire even prematurely. We present here a case study of 2×300 MWe wherein when the assets are managed effectively, the power plant can continue to operate and generate revenue for the asset owners.
C2.4 Reduce Flow Assurance Costs with Low Dose Hydrate Inhibitors
(2:00 pm – 2:20 pm EST)
C2.4 Reduce Flow Assurance Costs with Low Dose Hydrate Inhibitors
The goals of flow assurance are to prevent oil from cooling and to ensure its fluidity from the reservoir to the surface. One of the biggest issues for upstream production is the formation of hydrates. Hydrates form when light hydrocarbons and water mix under high pressures and low temperatures. Hydrates restrict flow and can form solid plugs that block production and damage equipment. Reliability and maintainability require that hydrates be eliminated in manner that frees space and increases efficiency.
C2.5 Optimizing Operational Benefits of High Reactivity Hydrated Lime

C3.1 Don't Just Monitor Your PM, Control It!
This presentation will attempt to show how concentrating on continuous emission monitoring systems (CEMS) for the last 8 – 10 years has caused us to lose our focus on controlling particulate matter (PM). This presentation will revisit the basics of good baghouse monitoring and particulate control. The presentation will also identify cost savings opportunities in baghouse operations as the PM is being lowered. The presentation will not be how to do emission monitoring, but how to reduce your emissions through diagnostic monitoring.
QUESTIONS
1. What’s the payback period of a diagnostic system?
2. How will it affect my current controls?
3. Can it work on baghouses other than pulse-jets?
C3.2 Cope Baghouse Retrofit Project
(4:20 pm – 4:40 pm EST)
C3.2 Cope Baghouse Retrofit Project
After 20 years of Dry FGD service on Eastern Bituminous coal, the reverse gas baghouse at the 410 MW Cope coal fired generating station had become severely corroded. The generation plan for Dominion called for this unit to be reliably operational for another 20 years. Extensive repair or replacement to correct air leakage and structural weakness in the baghouse casing would have required a long unit outage. Various alternatives were considered for cost, schedule, and technical risk. An innovative solution was to install a full flow bypass while the baghouse was still in service, and then fire natural gas in the boiler while the baghouse was being replaced. This minimized the outage time and enabled the unit generating capacity to be available for dispatch. Numerous design challenges were overcome in designing and installing the bypass while minimizing the impact on the existing equipment.
Alternatives considered for replacement of the baghouse were:
1. New epoxy coated carbon steel pulsejet filter located alongside the existing unit.
2. New epoxy coated carbon steel reverse gas baghouse located alongside the existing unit.
3. Demolition and replacement of the existing baghouse with an identical epoxy coated carbon steel duplicate in the original location.
4. Demolition and replacement of the original baghouse with an identical new 2205 alloy steel unit, in the original location.
The alloy steel alternative was chosen as the lowest risk solution long-term solution

C3.3 It’s All In The Dust Cake Revisited
(4:40 pm – 5pm EST)
C3.3 It's All in The Dust Cake Revisited
The most successful dry FGD plants are associated with optimized bag houses. After the FGD reaction in the main scrubber, a secondary SO2 neutralisation reaction takes place in the dust cake formed on the filter bags in the BH (bag house). An engineered dust cake improves the effectiveness of the neutralization reaction.
Test results performed on specific reference filter bags in large BHs substantiate the importance of a high-quality dust cake. The presentation will provide an update of our presentation to EUEC in 2018 with additional case studies demonstrating the influence of the filter media design on the SO2 removal.

C3.5 Unit Flexibility for Coal Fired Units
(5:20 pm – 5:40 pm EST)
C3.5 Unit Flexibility for Coal Fired Plants
Do to an abundance of cheap natural gas and an increase in renewable power generation, large coal fired power plants must adapt to this new market. To survive and thrive the coal fired units need to become much more flexible. This presentation covers the challenges involved within industry to adapt and operate the units to match today’s market. This will include results from on-site Unit Flexibility Testing at large coal fired units (750 MW Net) where minimum load was decreased from 50% down to 20-25% of rated full load, and unit ramp rates were increased from the normal 3-4 MW/min up to 12-15 MW/min. We will discuss potential issues like SCR inlet temperature, Steam Temperatures, Controls Tuning. Unit Flexibility allows the coal fired unit to turn down without shutting down. This avoids short term and long term issues related to cycling the unit on and off. It also provides a greater degree off power grid/system reliability on very short notice.

C3.6 Meeting Increasingly Stringent Medical Waste Incinerator Standards
Curtis Bay Medical Waste Services operates a dedicated medical waste incinerator permitted to process up to 150 tpd. Each of two incinerators has a dry injection scrubber/catalytic fabric filter (DI/FF), activated carbon injection (ACI) and selective non-catalytic reduction (SNCR). EPA regulates solid waste combustion emissions with limits for both criteria and hazardous air pollutants. The applicable federal regulations, first promulgated in 1997, were again revised in 2009. The facility has managed to comply with two generations of NOX, acid gas, heavy metal, and dioxin/furan limits, as well as stringent state air toxics rules, largely by upgrading existing emissions control systems.

D1.1 Increased Role of Medium Gas Turbines in Combined Cycle
(11 am – 11:20 am EST)
D1.1 Increased Role of Medium Gas Turbines in Combined Cycle
It’s no secret that the large gas turbine market has been declining in recent years. The increase of renewable generation has been one of the key contributors to this decline, and in the process is actually changing the way many grids operate. Therefore, flexibility in new plants is key to operating effectively. With recent advances in the medium gas turbine power range, combined cycle efficiency levels have increased dramatically. This has allowed smaller combined cycles to now be looked at as baseload plants, with an added level of redundancy and flexibility to their LGT counter parts. With the flexibility of multiple units and the advancements in higher efficiency, medium gas turbine combined cycle plants are an excellent fit to this continuously evolving grid.

D1.2 Thermal Power Plant Transformation: The Key to a Clean Energy Future
The electric energy industry is fundamentally transforming at several fronts with competing interests. Influx of renewables is disrupting the traditional role of conventional power generation. They are under growing pressure to demonstrate flexibility, reliability, and social responsibility. However, the existing power plants are more competitive with renewables than new builds, because with historically low gas price their variable O&M costs have significantly reduced, and capital investment to refurbish them is much lower than for new plant construction. The continued operation of E & F class machines, LM6000, 501D5 and likes is critical for successful transition to a clean energy future.

D2.1 Monitoring Fuel Gas Composition in Real Time Using an Optical Analyzer
(1:30 pm – 1:50 pm EST)
D2.1 Monitoring Fuel Gas Composition in Real Time Using an Optical Analyzer
The MKS Precisive® analyzer is an optical instrument designed for on-line quality monitoring of hydrocarbon gas fuels. It provides fast and accurate measurement of Calorific Value, Wobbe Index, Specific Gravity, and Methane Number along with compositional information, including CO2 in a single, compact, low cost instrument. The analyzer is based on MKS’ unique Tunable Filter Spectroscopy (TFS™) platform which directly measures the component concentrations in the gas as opposed to inferring the gas composition by measuring the bulk gas physical properties. When compared with gas chromatographic (GC) methods, the analyzer does not require carrier gas and provides fast measurements (every 1 to 5 seconds) in contrast to several minutes for GC. The recent addition of Methane Number as an integrated output of the analyzer for natural gas analysis facilitates the direct integration of the analyzer for process control. Applications include natural gas fuel quality analysis for gas turbines and internal combustion engines process control and tuning. Additional areas of use include CV measurement of by-product gases in steel manufacturing, as well as many others.

D2.3 Risk Categorization Underground Utility Cables
(2:10 pm – 2:30 pm EST)
D2.3 Machine Learning and Deep Learning Provide Risk Categorization to Underground Utility Distribution Cables
Underground distribution cable system failures can be predicted. Avoiding cable system failures begins with understanding how cables fail. Analyzing and interpreting results from partial discharge (PD) measurements taken in the field can be a complex task for humans. Machine learning algorithms and deep learning algorithms are used to automatically identify and categorize markers of defects contained in the PD measurements. These algorithms are used to categorize different defect types by risk of going to failures soon. Examples of identified defects will be presented. A roadmap to achieve broader utility distribution efficiencies, powered by machine learning and AI, will be presented.

D2.4 Monitoring Distributed Energy Assets with Drones
In his presentation, Jay will discuss how utilities can better monitor and maintain distributed and remote energy assets with the help of drones and drone software.
From maintaining solar panels or microgrids to traditional transmission lines, all types of utilities companies still struggle with the time and safety considerations of keeping remote equipment overseen and adequately serviced. With the help of drones, companies can improve their inspection processes and collect better data on the state of their equipment; therefore staying on top of continually evolving exterior conditions and identifying potential issues before they arise. With an accompanying data platform, these inspections can also be logged, analyzed, and shared across remote teams, reducing the need to dispatch workers to remote locations and introducing new levels of insight across the entire organization.

D3.5 Reducing GHG Emissions with High Ampacity Conductor
TS Conductor’s patented design technology delivers the perfect balance between increased strength, reliability and conductivity. The combination of encapsulated carbon core, annealed aluminum, and advanced insulation compounds offers 2X the strength, temperature operation up to 400F, and virtually no thermal expansion/sag compared traditional ACSR. The efficiency of TS Conductor optimizes the power grid, decreasing the need for additional power generation and maximizing renewable energy interconnections. the efficiencies alone create significant savings for utilities per installed mile and GHG emission avoidance from compensatory generation. Additionally, the high ampacity, low sag of this product allows hardening and reconductoring using existing infrastructure, versus requiring retrofits/rebuilds. The high temperature low sag aspects allows increased span distances, requiring 30%-50% fewer structures for new line builds or replacement construction. This provides added environmental savings by reducing construction and land disturbances. TS Conductor is superior in longevity, and is immune from galvanic corrosion or other environmental degradation, which also reduces construction and reconductoring.
QUESTIONS
1. How does TS Conductor reduce CO2 emissions?
2. How do you differ from other conductors?
