Methanol Production System that Reuses Unreacted Gas for Efficient Methanol Production

Abstract

A methanol production system capable of improving methanol production efficiency is provided. The methanol production system includes a waste gas reformer configured to reform a waste gas comprising a hydrocarbon (CxHy) gas and carbon dioxide to generate synthesis gas containing hydrogen, carbon monoxide, and carbon dioxide; a methanol production reactor including a first reaction zone to which a portion of the synthesis gas is supplied to generate methanol in the presence of a first catalyst, and a second reaction zone to which a remaining portion of the synthesis gas is supplied to generate methanol in the presence of a second catalyst; a condenser configured to condense methanol and water from gas discharged from the methanol production reactor; and a gas separator configured to separate a recycle gas comprising hydrogen, or a mixture of hydrogen and carbon monoxide, from gas discharged from the condenser after methanol and water are condensed and separated.
