摘要： Disclosed herein are processes for producing and separating ethane and ethylene. In some embodiments, an oxidative coupling of methane (OCM) product gas comprising ethane and ethylene is introduced to a separation unit comprising two separators. Within the separation unit, the OCM product gas is separated to provide a C2-rich effluent, a methane-rich effluent, and a nitrogen-rich effluent. Advantageously, in some embodiments the separation is achieved with little or no external refrigeration requirement.

摘要： The present disclosure provides methods and systems for producing an olefin, such as ethylene and propylene. A method for producing an olefin can comprise injecting an oxidizing agent and methane into an oxidative coupling of methane (OCM) reactor to generate ethylene. The methane and/or additional feedstocks for the OCM reactor can be derived from a thermal cracking or fluidized catalytic cracking (FCC) process. The ethylene generated in the OCM reactor can be converted to propylene through a dimerization unit and metathesis unit.
