“MERCURY MEASUREMENT AND CONTROL”

PART 3

PAUL BARILLA and JOHN DARROW - W. L. GORE

BIO: Paul Barilla is an Applications Engineer with W. L. Gore & Associates, Inc. on the GORE Mercury Team. Paul previously worked for General Electric and PPL Generation on emission control projects.  He has a BS in Mechanical Engineering from Penn State and is a registered Professional Engineer in Pennsylvania.

BIO: John Darrow is a member of the GORE Mercury Team, part of the Industrial Product Division of W. L. Gore & Associates, Inc. (Elkton, MD). He has worked in air pollution control for more than 35 years. Over his career he has been involved in power plant design, air pollution modeling, specifying and purchasing electrostatic precipitators, and sales of air pollution equipment. John’s current commitment is market development for new GORE Mercury Control System for power plants and other industrial applications.

Prior to joining Gore he worked for Sargent & Lundy Engineers, the Buell Division of Envirotech, Wheelabrator-Frye and Niro Atomizer. John has a B.S in Civil Engineering from Drexel University. He has written and co-authored several papers on fabric filtration for industrial and power generation boilers and municipal solid waste and incinerators.

ABSTRACT: W.L. Gore & Associates has developed a unique approach to mercury control based on a sorbent polymer composite material (SPC) contained within a fixed-structure located in the gas stream. SPC has a high affinity for absorption and retention of mercury in both elemental and oxidized states and requires no sorbent or chemical addition, thus avoiding potential adverse effects on fly ash salability and balance-of-plant equipment. The GMCS is ideally located in a wet FGD absorber vessel, downstream of the mist eliminators, where it also serves as a barrier to scrubber re-emissions. Removal of SO₂ is a co-benefit of the GORE Mercury Control System.

JOE STUART – TDC, LLC (Division of Genesis Energy Limited)

BIO:  Mr. Stuart is a graduate of Louisiana State University with over thirty years of industrial experience in the chemical, petrochemical, and petroleum refining industries.  Having directed the development and detailed design of several large scale chemical facilities, he brings to the power industry a unique approach to challenging assumptions and resetting expectations for achieving co-absorption of mercury in existing wet flue gas desulfurizers.

ABSTRACT: Achieving Maximum Mercury Emission Reduction from Your Wet Flue Gas Desulfurizer 

Your wet flue gas desulfurizer is likely an underappreciated piece of an overall cost-effective mercury-emission reduction strategy.  Having been misdirected by the concept of “mercury re-emission”, the industry has missed the opportunity to maximize co-absorption of mercury in wet FGDs.  Applying basic engineering concepts to the mercury issue, an operating point can be found which reliably avoids stripping of elemental mercury (previously known as “re-emission”), maximizes the ability to absorb elemental mercury up to the mass-transfer limit of your system, and avoids the costs and side-effects of excess oxidation of mercury in the inlet gas.  Results from commercial scale trials will be presented.'

MARK SANKEY – BECHTEL POWER

 BIO: Mr. Sankey has more than 35 years experience in design, proposal preparation, engineering, and project execution on a variety of air pollution control projects. He has understanding of SCR, SNCR, dry and wet ESP, fabric filter, and acid gas removal technologies, including wet and dry FGD, and sorbent injection systems.  Mr. Sankey has authored several technical papers and contributed to ICAC’s Electrostatic Precipitator Division.

ABSTRACT: Mercury Control for Coal-fired Power Plants – Interaction of Other Technologies

This presentation will review the effectiveness of existing control equipment and capabilities of new equipment and technologies as they relate to control of mercury emissions.  The concepts of multi-pollutant control, co-benefits, and the interrelationships of various technologies and pollutants will be addressed.  This will include discussion of undesirable effects that occur due to interactions between various pollutants and technologies.
