Patent

CA 2458639

The present invention provides a process treating the cycle gas from an ethylene oxide reactor to avoid heat losses in a carbonate scrubbing system as well as glycol formation in the carbonate scrubbing and catalyst contamination upon cycle gas recycle. The Figure (1/1) is a schemmatic representation of the claimed process.

L'invention concerne un procédé destiné à traiter un gaz de recyclage provenant d'un réacteur à l'oxyde d'éthylène afin d'éviter des pertes de chaleur dans un système d'épuration du carbonate. L'invention concerne également la formation du glycol au cours de l'épuration du carbonate et la contamination du catalyseur au cours du recyclage du gaz de recyclage. La figure (1/1) est une représentation schématique du procédé dont la protection est demandée.
