Processes and systems for removing an alkyl iodide impurity from a recycle gas stream in the production of ethylene oxide

摘要

Processes for reducing the amount of a gaseous iodide-containing impurity present in a recycle gas stream used in the production of ethylene oxide, in particular an alkyl iodide impurity, are provided. Processes for producing ethylene oxide, ethylene carbonate and/or ethylene glycol, and associated reaction systems are similarly provided.
