Abstract: The invention relates to a process for the production of ethylene oxide, comprising the steps of: producing ethylene resulting in a stream comprising ethylene and ethane; separating the stream comprising ethylene and ethane into a stream comprising ethylene and ethane in which stream the amount of ethylene is greater than the amount of ethane and a stream comprising ethane and ethylene in which stream the amount of ethane is greater than the amount of ethylene; producing ethylene oxide by subjecting ethylene and ethane from the stream comprising ethylene and ethane, in which stream the amount of ethylene is greater than the amount of ethane, to oxidation conditions resulting in a stream comprising ethylene oxide, unconverted ethylene and ethane; and recovering ethylene oxide from the stream comprising ethylene oxide, unconverted ethylene and ethane

Abstract: A process for recovering an ethylene oxide (EO) enriched product stream from fat absorbent (FA) comprising water, EO, and acetaldehyde. The process comprises passing a feed of FA from a loopgas EO absorber to a multi-stage countercurrent distillation zone, the feed of FA having a concentration of EO in the range of from about 1 to about 15 wt % upon entering the distillation zone; and obtaining from the distillation zone an acetaldehyde enriched stream, a lean absorbent (LA) stream, a vapor stream enriched in light ends, a glycol enriched bottoms stream and an EO enriched product stream. Suitable apparatus is also disclosed.
