摘要： 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.

摘要： A method for operating a plant for synthesizing methanol, wherein a synthesis gas flow having hydrogen and carbon oxides is supplied to a synthesis gas compressor of the plant to increase the pressure of the synthesis gas flow. The pressure-increased synthesis gas flow is supplied to a methanol reactor arrangement of the plant for partial conversion to methanol. The plant has a hydrogen recovery arrangement which obtains an H-recycling flow including hydrogen from a recovery flow supplied from the methanol reactor arrangement, which hydrogen is converted at least in part to methanol. Upon failure of the synthesis gas compressor, the synthesis gas flow continues to be supplied to the methanol reactor arrangement for partial conversion to methanol. Following failure of the synthesis gas compressor, a line arrangement of the plant is switched such that the H-recycling flow is adjusted to compensate for a pressure loss in the methanol reactor arrangement.

摘要： Method and system for the combined production of methanol and of ammonia, and method for producing a fuel using methanol, wherein a carbon-containing energy carrier flow and an oxygen flow from an oxygen-producing assembly are fed to a synthesis gas reactor assembly for obtaining a synthesis gas flow with hydrogen and carbon oxides, wherein the synthesis gas flow is fed to a methanol reactor assembly for the partial conversion into methanol, and wherein, from the methanol reactor assembly, a residual gas flow is obtained from which a hydrogen-containing flow is obtained, which is at least partially fed to an ammonia reactor assembly and at least partially converted into ammonia there. In an enrichment step, the molar fraction of hydrogen in the synthesis gas flow obtained from the synthesis gas reactor assembly is increased relative to the molar fraction of carbon oxides prior to the feeding to the methanol reactor assembly.

摘要： The invention relates to a method for producing ammonia (1), wherein a carbon-containing energy carrier flow (2) and an oxygen flow (3) from an oxygen-producing assembly (4) are fed to a synthesis gas reactor assembly (5) for obtaining a synthesis gas flow (6) with hydrogen and carbon oxides, wherein the synthesis gas flow (6) is fed to an adsorption device (7) for separating the synthesis gas flow (6) into a hydrogen flow (8), which comprises hydrogen, and a purge flow (9), and wherein the hydrogen flow (8) and a nitrogen flow (10) are fed to an ammonia reactor assembly (11) and converted into ammonia (1) there. The method is characterized in that the purge flow (9) is fed to a recovery device (12), which obtains a hydrogen-containing recovery flow (13) from the purge flow (9) and discharges a waste gas flow (14) therefrom, and that the hydrogen of the recovery flow (13) is at least partly fed to the ammonia reactor assembly (11) for conversion into ammonia (1). The invention also relates to a corresponding system for the production of ammonia (1).

摘要： A method for synthesizing methanol, wherein a fuel stream containing carbon is supplied to a synthesis gas reactor arrangement to obtain a synthesis gas stream including hydrogen and carbon oxides that is supplied to a first reactor stage of a methanol reactor arrangement for partial conversion into methanol, and is obtained with a generation pressure higher than the synthesis pressure with which the synthesis gas stream is partially converted into methanol. A residue gas stream is obtained from the methanol reactor arrangement, supplied to a recycle compressor and to the methanol reactor arrangement. Before being supplied to the first reactor stage, the synthesis gas stream is supplied to a heat recovery device to recover heat. A recovery stream is supplied to a hydrogen recovery arrangement to obtain an H-recycle stream. The pressure of the unreacted hydrogen is increased before it is supplied again to the first reactor stage.
