Scrubbers - Import export

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

The air from the Granulators and the Coolers contains urea dust that is entrapped in Hamon’s scrubbers. In these industrially proven impact type scrubbers, efficiencies are very high and dust concentrations lower than 20 mg/Nm3 can be achieved at the stack outlet. The total amount of urea collected by these scrubbers is recycled, for reconcentration, to the process.The same process is used to capture NH3 from the gases at the outlet of the Fertilizer Industry.
