The multi-pollutant control ReACT™ technology is a completely dry scrubbing system based on adsorption of SO2, SO3, and Hg and reduction of NOx to N2 on activated coke in a moving bed, with regeneration of the coke for return to the adsorber, and production of saleable byproduct, such as sulfuric acid, from desorbed sulfur rich gases.

For about 50 years, polychlorinated biphenyls (PCBs) were commonly used in industrial
materials including, caulking, cutting oils, inks, paints and as dielectric fluids in electrical
equipment such as transformers and capacitors. Concerns over health effects led to a North
American ban of manufacturing PCBs in 1977. By the mid-1980s, an initiative was started to
clean up contaminated areas and to phase out PCB-containing equipment and products that
were still in use. This cleanup effort continues today.

Groundwater at an industrial site in Texas is impacted with Chlorinated Volatile Organic Carbon’s
(CVOCs), primarily PCE and TCE, from historical waste disposal. The topography at the site slopes
steeply towards a small channel where the groundwater discharges. Depth to groundwater ranges from
approximately 20 ft bgs at the source area to 1 ft bgs close to the channel.
