PLANT AND METHOD FOR PRODUCING ETHYLENE

A plant for producing ethylene having: a reactor to effect oxidative coupling of methane, a work-up unit connected to the reactor to separate a first material stream produced by the reactor into a C1− material stream and an ethylene product stream and a separation unit connected to the work-up unit...

More Information
Summary:A plant for producing ethylene having: a reactor to effect oxidative coupling of methane, a work-up unit connected to the reactor to separate a first material stream produced by the reactor into a C1− material stream and an ethylene product stream and a separation unit connected to the work-up unit to separate the C1− material stream at least into a hydrogen-rich product stream and a hydrogen-lean residual gas stream. The plant also includes a steam cracker to produce (5) for producing an olefin-containing and hydrogen-containing crude gas stream. The steam cracker is connected to the work-up unit that separates the crude gas stream along with the first material stream into the C1− material stream and the ethylene product stream. A portion of the residual gas stream is recycled to the reactor. A process for producing ethylene using the plant is also described.
