  • Process for the removal of ethylene oxide from air
    Patent number: 6837917
    Abstract: A process for removal of ethylene oxide (EO) from ambient air laden with EO is passed through a zeolite-based removal media, which preferrably consists of the acid form of zeolite ZSM-5, herein referred to as “H-ZSM-5.” The process described herein may be applied to many forms, configurations and uses, such as, for example, gas masks, fume hood ventilation filters, cartridge filters, etc. Preferably, the H-ZSM-5 is configured within an apparatus in such a manner that the stream containing EO is brought into sufficient contact with the zeolite to remove the EO from the airstream.
