Oxygen removal from an ethane ODH product stream using ethanol

Abstract

A method and a system for converting ethane to ethylene are provided. An exemplary method includes providing a feed stream including the ethane and oxygen to an oxidative dehydrogenation reactor and converting at least a portion of the ethane to ethylene in the oxidative dehydrogenation reactor to provide a reactor effluent stream including ethane, ethylene, and oxygen, acetylene, or both. The method includes cooling the reactor effluent stream to form a cooled effluent stream and providing the cooled effluent stream to an oxygen removal reactor including an ODH catalyst bed. A deoxygenation stream including water and an alcohol is provided to the oxygen removal reactor to form a deoxygenated effluent.
