Abstract
A process and reaction system for preparation of methanol. A fresh methanol synthesis gas stream is introduced in a first methanol reaction unit in the presence of a methanol catalyst, resulting in a first effluent stream containing methanol and unconverted synthesis gas. A recycle gas stream containing the unconverted methanol synthesis gas contained in the first effluent stream and unconverted methanol synthesis gas from a second methanol reaction unit is introduced and reacted in the second methanol reaction unit in the presence of a methanol catalyst. The first effluent stream and a part of a second effluent stream containing methanol and the unconverted methanol synthesis gas from the second methanol reaction unit are combined, cooled, and separated into a methanol-containing liquid stream and the recycle stream. The remaining part of the second effluent stream is withdrawn as a purge gas stream prior to combining the first and second effluent streams.
