Presentation #1 – GPS Denied UAS Inspections for Scrubbers by Matthew Wilson (TVA) and James Manni II (TVA)

Large equipment has always presented access difficulties for internal inspections. In this presentation, TVA reviews the technology and equipment utilized to execute Global Positioning System (GPS) denied Unmanned Aircraft System (UAS) inspections. TVA’s drone use enables a better definition of work scope and risks, for both coal unit’s wet and dry flue gas desulfurization (WFGD & DFGD) systems; all without scaffolding costs, while fitting within short outage durations. Examples of findings, access benefits, and actual video and still images discussed.

Presentation #2 – Sorbent Injection Performance Improvement by using Chemistry-Based CFD Simulations by Guisu Liu (Reaction Analytic Solutions) and Sean Dooley (Nol-Tec Systems, Inc.)

This presentation discusses about an advanced CFD tool to cost-effectively assist in identifying optimizing solutions Dry Sorbent Injection (DSI) systems, using proprietary chemical kinetic submodels for reactions between sorbent particles (Ca or Na-based) and acid gas species (SO2, SO3, HCl, Hg). Unlike conventional flow-only CFD model, the chemistry-based advanced CFD model allows for predicting gas species distributions and reduction level under specified operating conditions, therefore can be used to evaluate DSI injection system design or mixing device, as well as sorbent properties. Several recent case studies will be presented to demonstrate how this advanced tool has helped in finding the detailed DSI engineering solutions.

CONFERENCE NEWS

2021 In Person Conference: DSUA Participating in the EnviroSummit (September 14-17, 2021 in Charlotte, NC)

DSUA is excited to announce that we will be participating at the 2021 Global EnviroSummit in person conference. Here is what you need to know:

What is the EnviroSummit?

The EnviroSummit is a 3-day global conference with international presentations in the morning on the main stage, and breakout sessions for Remediation, Vapor Intrusion, Air Quality and Waste Water in the afternoon. The mission is to accelerate trends and advance technologies in our industry. If you’d like to learn more please visit their website http://www.envirosummit.com/.

How is DSUA involved with EnviroSummit?

DSUA is promoting and endorsing this 2021 event as a means for those interested in Air Quality (specifically around dry scrubbing applications) can congregate in person to learn and network. In addition, DSUA will be specifically allotted slots during the break-out sessions to present content. Anyone interested in learning more about the use of Spray Dryer Absorbers, Circulating Dry Scrubbers and Dry Sorbent Injection (as well as use of the ancillary particulate control device) to control acid gas emissions should attend the DSUA break-out sessions at EnviroSummit.

When and where is the 2021 EnviroSummit?

The event will be held from September 14-17, 2021 in Charlotte, NC at the Sheraton Charlotte Hotel.

How do I register?

You can register at the following link: Get Tickets. As a participant from DSUA you can use the discount code of “DSUA25” to receive 25% off your registration fee.

How do I present during the DSUA break-out session at the EnviroSummit?
