1. A process for producing methanol, comprising:
a) providing and compressing a make-up gas stream, wherein the make-up gas stream comprises at least one carbon oxide and hydrogen;
b) reacting a synthesis gas stream in a synthesis stage over a solid methanol synthesis catalyst, wherein raw methanol and a residual gas stream are obtained and wherein the raw methanol after cooling and condensation as liquid reaction product and the residual gas stream are discharged from the synthesis stage;
c) combining the residual gas stream with the make-up gas stream to obtain the synthesis gas stream,
wherein the residual gas stream and the make-up gas stream are combined using a jet pump, wherein the compressed make-up gas stream is supplied to the jet pump as motive medium via its motive media connection at a pressure p1 and the residual gas stream is supplied to the jet pump as suction medium via its suction port at a pressure p3 and wherein the synthesis gas stream is discharged from the jet pump via its pressure port at a pressure p2 and subsequently supplied to the synthesis stage and wherein p1>p2>p3.
