ABSTRACT:
A method of removing low levels of ethylene oxide (1% by volume or less) from ethylene oxide contaminated gases is provided. The removal is effected by contacting the ethylene oxide with a solid, cationic ion exchange resin at conditions such that the quantity of water present in the reaction zone is at a level such that the reaction of the ethylene oxide with resin occurs at a gas-solid interface to form an ethylene oxide derivative polymer which is bound to said resin.
