Abstract
An improved process is disclosed for producing ethylene oxide; the process utilizing suitable semipermeable membrane units to selectively remove desired amounts of both carbon dioxide and argon diluents from the reaction recycle gas. The utilization of such a process makes possible to utilize a much cheaper low purity oxygen source without concern for feed purge losses.
