Expert Witness #260698

This expert leads the technical staff of an internationally renowned consulting firm that serves major power generation technology developers and sells commercial software packages worldwide. This expert is also recognized throughout the world as the author of over 240 technical papers on air pollutant formation and control.

This expert and consultancy performed sponsored research to develop and validate detailed chemical reaction mechanisms to predict the partitioning of mercury (Hg) along coal-fired utility gas cleaning systems. These mechanisms accurately describe the fate of Hg as flue gas moves through economizers, SCR units, air preheaters, ESPs and fabric filters, and FGD scrubbers in utility power plants. They also accurately predict Hg capture efficiencies for bromine and chlorine additives, activated carbon injection, and the full domain of gas cleaning conditions. The predictions have been validated with measured Hg speciation from over 200 field tests at commercial power plants.

This expert's firm's reaction mechanism for bromine/chlorine/Hg chemistry is regarded worldwide as the best-in-class. Collectively, this expert's publications on Hg control have been cited more than 800 times and research also spawned three patent applications. The work also spawned two software packages.

This expert has served as an expert witness on two cases of patent infringement involving Hg control with bromine and activated carbon at coal-fired power stations.
