Abstract: 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.

Abstract: 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.
