Abstract:
In a novel process for methanol production from low quality synthesis gas, in which relatively smaller adiabatic reactors can be operated more efficiently, some of the inherent disadvantages of adiabatic reactors for methanol production are avoided. This is done by controlling the outlet temperature in the pre-converter by rapid adjustment of the recycle gas, i.e. by manipulating the gas hourly space velocity in the pre-converter.

Claim (Index 1):
A process for methanol production from synthesis gas comprising the following steps:\n providing a fresh, pressurized methanol synthesis gas containing hydrogen, carbon monoxide and carbon dioxide, which is pre-heated and passed through a methanol pre-converter/guard reactor, in which the synthesis gas is partially converted to methanol over a heterogeneous methanol catalyst and poisonous impurities are removed from the feed gas, providing a recycle gas stream containing partly converted methanol synthesis gas and mixing a part of the recycle stream with the fresh synthesis gas if necessary, such as in case of part load, to a process gas stream, cooling the process gas stream from the pre-converter/guard reactor to a temperature, which is suitable for the main converter, and passing the cooled process gas stream to a conventional methanol synthesis loop, and separating raw methanol from the synthesis loop, wherein the outlet adiabatic temperature in the pre-converter/guard reactor is controlled by rapid adjustment of the recycle gas, i.e. by manipulation of the GHSV (gas hourly space velocity) in the pre-converter.
