Abstract
Systems and methods for producing ethylene oxide (EO) are disclosed. Ethylene oxide is produced by direct oxidizing ethylene with oxygen in a reactor. The effluent from the reactor is processed to produce (a) a product stream comprising water and ethylene oxide, (b) a reabsorber overhead stream comprising ethylene, methane, argon, and carbon dioxide, and (c) a carbonate flash gas stream comprising carbon dioxide, ethylene, methane, and water. The reabsorber overhead stream and the carbonate flash gas stream are combined to form a reclaim gas stream. The reclaimed gas stream is separated in a membrane separation unit to remove carbon dioxide and argon, forming a recycle stream comprising primarily ethylene and methane, collectively.
