Abstract:
A process for the production of dimethyl ether from a methanol reactor effluent is disclosed. The process may include: contacting an aqueous extractant comprising water and an effluent from a methanol synthesis reactor comprising methanol and one or more of methane, water, carbon monoxide, carbon dioxide, hydrogen, and nitrogen. At least a portion of the methanol partitions into the aqueous extractant; recovering an extract fraction comprising the aqueous extractant and methanol. The extract fraction is fed to a catalytic distillation reactor system for concurrently: contacting the methanol with catalyst in a reaction zone thereby catalytically reacting at least a portion of the methanol to form dimethyl ether and water; and fractionating the resulting dimethyl ether and the water to recover a first overheads fraction comprising dimethyl ether and a first bottoms fraction comprising water.
