Air pollution controller - Import export

Dr. Frederick Cottrell developed the first wet electrostatic precipitator (WESP) in 1907 to control sulfuric acid mist from a copper smelting process in Pinole, California.Since that time WESP technology has become well-established in both industrial and utility applications around the world to remove sub-micron particulate, condensables, and acid mist as a final polishing device in an air pollution control system where an upstream dry ESP, fabric filter or wet scrubber cannot capture the sub-micron particulate due to its small size.

ExxonMobil’s Wet Gas Scrubbing (WGS) technology allows refiners to reliably meet tough FCC emission regulations with well-proven technology.In 2002 and 2003, ExxonMobil Research and Engineering Company (EMRE) and Hamon Research-Cottrell (HR-C), entered into licensing and sublicensing agreements to provide ExxonMobil’s Wet Gas Scrubbing technology to sublicensees of HR-C.Expect these advantages:Can avoid costly CO boiler upgrades with allowable scrubber pressure drops as low as zero inches of water, Takes advantage of HRC’s almost 100 years of experience and global leadership position in providing air pollution control equipment to a wide range of industries, including refineries.Maximizes cat cracker availability - scrubber run lengths match longest FCC up-time in the industry, Meets or exceeds toughest particulate and SOx emission regulations, Produces environmentally benign wastewater safe for direct discharge, Collected catalyst suitable for direct low cost disposal
