Deoxygenization from ethane ODH product streams using ethanol

Processes and systems for converting ethane to ethylene are provided. An exemplary process includes providing a feed stream comprising 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 comprising ethane, ethylene and oxygen, acetylene, or both. The method includes cooling a 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 deoxygenated stream comprising water and alcohol is provided to a deoxygenated reactor to form a deoxygenated effluent. 提供了用于将乙烷转化为乙烯的方法和系统。示例性方法包括向氧化脱氢反应器提供包含乙烷和氧气的进料料流，并在氧化脱氢反应器中将至少一部分乙烷转化为乙烯，以提供包含乙烷、乙烯以及氧气、乙炔，或两者的反应器流出物料流。该方法包括冷却反应器流出物料流以形成经冷却的流出物料流并将经冷却的流出物料流提供至包括ODH催化剂床层的除氧反应器。将包含水和醇的除氧料流提供至除氧反应器以形成脱氧流出物。
