Abstract
Proposed is a process for producing methanol from synthesis gas by means of multi-stage, for example 2-stage, heterogeneously catalyzed methanol synthesis, wherein the methanol product formed in every synthesis stage is removed by condensation and the remaining residual gas is applied to the downstream synthesis stage or after removal of a purge stream recycled to the first synthesis stage as a recycle stream. According to the invention a substream is removed from the synthesis gas fresh gas and introduced into the second methanol synthesis reactor as a bypass stream.
