CR Clean Air - Ethylene Oxide and Propylene Oxide Scrubber
Ethylene Oxide (EO or Eto) and Propylene Oxide (PO) are commonly used as a sterilant in the medical and food industries and in the manufacturing of chemical products like surfactants. While both compounds can be dissolved easily in water and hydrolyzed to form ethylene and propylene glycol, their removal can be complex.
Both EO and PO are characterized by relatively high vapor pressures in aqueous solution. Consequently, unless the EO and PO are transformed into other substances in solution, the scrubbing liquid stream cannot practically be recirculated within the scrubbing system and still result in effective removal. The alternative, using once-through water for scrubbing, is not generally practical due to the cost of the water and its treatment. However EO and PO can be transformed to their respective glycols when hydrolyzed but the hydrolysis reaction is very slow.
The Clean Air Group, LLC EO and PO scrubbing systems have been designed to provide efficiencies of removal of in excess of 99.999% when needed. These systems can be supplied in the form of the major components only all the way to a completely skid mounted, instrumented, and automatically controlled package.
