B2.2 CFB Baghouse Optimization given the Use of Gore Membrane Filter Technology Advancements
(10:50 am – 11:10 am PDT)
B2.3 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.

B4.3 Emissions Monitoring with Multi-Gas FTIR in Carbon Capture and Storage Processes
This presentation reviews FTIR principles, sampling solutions, and available configurations for online gas analysis at carbon capture 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.
Emissions monitoring with multi-gas FTIR in carbon capture and storage processes Carbon capture plants deploy amines which degrade into ammonia, formamide, aldehydes, organic acids, nitrosamines and other toxic gaseous species. They pose challenges for sampling and gas 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 asymmetric compounds absorb infrared light, allowing to simultaneously measure more than 25 gases. FTIR analytes include standard criteria pollutants such as CH 4 , CO 2 , NOx, SO 2 , acid gases, NH 3 , aldehydes, and other VOCs, and extend to amines and amine by products observed in CO 2 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 gas emissions monitoring and online analysis at carbon capture and storage plants. It highlights industrial and laboratory scale case studies using semi portable and continuous emissions monitoring systems, and advantages as related to analytical performance, component flexibility, and maintenance requirements.

B2.5 Digitizing Visual Emission Observations — Bringing Opacity into the Digital Age
(11:50 am – 12:10 pm PDT)
B1.3 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
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?

B2.6 Indoor Air Quality Modeling and Health Impacts
(12:10 pm – 12:30 pm PDT)
B4.2 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.

B3.1 What is a Digital Transformation and How Do I Get Started?
(1:00 pm – 1:20 pm PDT)
B3.2 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.

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?
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
(1:40 pm – 2 pm PDT)
B3.4 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
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 Continuous Remote Environmental Monitoring
(2 pm – 2:20 pm PDT)
B6.2 Continuous Remote Environmental Monitoring
Environmental concerns and the perception of negative impacts from industry operations are ever present from the public and are bringing increased regulatory oversight. Technology now allows for numerous options when monitoring and collecting environmental data, including recent improvements in the use of telemetry and remote sensors with 24/7 data gathering. Systems include real time alerts when “Parameters of Concern” are reached, so an unlimited number of company personnel can be made aware of impending issues before they become serious situations. This presentation covers various types of remote access monitoring options such as blasting or construction vibrations, rain gauges, weather stations and high accuracy lightning detection & tracking. Surface and/or groundwater related monitoring includes parameters such as water levels, flow rates, pH, turbidity, conductivity, temperature, ORP, etc. Remote dust monitoring of PM 2.5, PM 10 and TSP is also available. These new systems can be self maintained, or operated via use of 3rd party turnkey companies where all installation, maintenance, calibrations, sensor tracking / replacements, etc. are covered, and your only concern is tracking the parameters and data and downloading time/date specific reports when necessary. Case studies of ongoing remote monitoring situations will be reviewed.

B3.5 Considerations for Certifying Photometric PM 2.5 & PM 10 Monitors
(2:20 pm – 2:40 pm PDT)
B4.5 Considerations for Certifying Photometric PM 2.5 & PM 10 Monitors
Many countries have established particulate mass (PM2.5 and PM10) reference methods for measuring ambient aerosols in the outdoor environment. Continuous real-time photometric systems to measure ambient aerosols are available for use as indicative and near-reference systems to monitor fugitive emissions from facilities, remediation sites and construction activities. These indicative systems can be used in addition to or in lieu of reference method monitoring systems. These near-reference units are simple to use, configurable, designed for purpose, require less effort and support to setup and run, and cost much less than their reference method counterparts. While they may not have a federal reference certification they do have localized certifications and can be very useful in monitoring many fence-line real-time applications.
This presentation will outline fence-line and remediation outdoor fugitive monitoring and the advantages of deploying lower cost PM instruments. These instruments can be effectively deployed for continuous, real-time, direct reading indicative instruments for source apportionment ambient aerosol measurements.
B3.6 Using Unmanned Aerial Systems for Compliance and Process Monitoring
(2:40 pm – 3 pm PDT)
B6.3 Using Unmanned Aerial Systems for Compliance and Process Monitoring
Until now, Regulatory Compliance monitoring and RATA testing has traditionally been performed from the ground using expensive Continuous Emissions Monitoring Systems (CEMS) and stack testing teams armed with trailers full of expensive analyzers, sample conditioning equipment and exorbitant overhead. With our latest AeroCEMS platform, CEMS Experts has lifted the industry to new heights using Unmanned Aerial Vehicle (UAV) technology coupled with state-of-the-art measurement equipment and proprietary sampling solutions which enable accurate, reliable process and compliance monitoring from fixed and ambient sources at a fraction of the cost of traditional methods. Now the sky is no longer the limit!
B4.1 Air Quality Modeling Options for Capped and Horizontal Stacks
(3:30 pm – 3:50 pm PDT)
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.

C2.5 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.
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?
(4:10 pm – 4:30 pm PDT)
B4.4 NO2 to NO Converter Selection and Maintenance
(4:30 pm – 4:50 pm PDT)
B4.6 NO2 to NO Converter Selection and Maintenance
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

B1.1 EPA Signs New Rule Affecting Stationary
In 2019, the DC Circuit dealt a major setback to EPA’s efforts to resolve and close-out interstate air quality issues under the 2008 ozone standard without further NOx reductions from power plants. In doing so, the court may have breathed new life into state petitions to EPA demanding more stringent NOx limits for plants in numerous states. This presentation will review these recent decisions, the state petitions seeking NOx reductions in downwind states, and discuss the potential implications for industry.
