Abstract: For producing methanol from a synthesis gas containing hydrogen and carbon oxides the synthesis gas is passed through a first, water-cooled reactor in which a part of the carbon oxides is catalytically converted to methanol. The resulting mixture containing synthesis gas and methanol vapor is supplied to a second, gas-cooled reactor in which a further part of the carbon oxides is converted to methanol. Subsequently, methanol is separated from the synthesis gas, and synthesis gas is recirculated to the first reactor. The cooling gas flows through the second reactor cocurrent to the mixture withdrawn from the first reactor.

Abstract: For producing methanol from a synthesis gas containing hydrogen and carbon oxides the synthesis gas is passed through a first, preferably water-cooled reactor in which a part of the carbon oxides is catalytically converted to methanol, and the resulting mixture containing synthesis gas and methanol vapor is supplied to a second, preferably gas-cooled reactor in which a further part of the carbon oxides is converted to methanol. The mixture withdrawn from the first reactor is guided through a gas/gas heat exchanger in which the mixture is cooled to a temperature below its dew point. Subsequently, methanol is separated from the gas stream in a methanol separator and withdrawn, while the remaining gas stream is supplied to the second reactor.

Abstract: In the production of methanol from a synthesis gas containing hydrogen and carbon oxides, the synthesis gas is passed through a first, preferably water-cooled reactor, in which a part of the carbon oxides is catalytically converted to methanol. The obtained mixture containing synthesis gas and methanol vapor is supplied to a second, preferably gas-cooled reactor, in which a further part of the carbon oxides is converted to methanol. Subsequently, methanol is separated from the synthesis gas, and the synthesis gas is recirculated to the first reactor. To achieve a maximum methanol yield even with an aged catalyst, a partial stream of the synthesis gas is guided past the first reactor and introduced directly into the second reactor.
