Abstract
A method for the synthesis of methanol, wherein a carbonaceous energy source flow is supplied to a synthesis gas reactor arrangement for obtaining a synthesis gas flow having hydrogen and carbon oxides, wherein the synthesis gas flow is supplied to a thermal recovery apparatus for recovering heat from the synthesis gas flow and then to a synthesis gas compressor for pressure increase. The synthesis gas flow is supplied at least in part to a first reactor stage of a methanol reactor arrangement for partial conversion to methanol, a residual gas flow having unreacted carbon oxides being obtained from the methanol reactor arrangement, which residual gas flow is supplied to a recycling compressor for increasing its pressure, the pressure-increased gas flow being supplied to the methanol reactor arrangement for partial conversion to methanol, a recovery flow from an unreacted residual gas being supplied to the first reactor stage of a hydrogen recovery arrangement to obtain a H-recycling flow.
