    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： A process for the combined production of methanol and ammonia, wherein a reactant stream includes carbon monoxide is supplied to a recovery assembly to obtain first and second hydrogen-containing streams, each having an increased molar proportion of hydrogen compared to the reactant stream. The recovery assembly includes a shift conversion in which the carbon monoxide of at least one carbon monoxide-containing stream is at least partially converted into hydrogen and carbon dioxide by reaction with steam to obtain a converted stream having hydrogen and carbon dioxide at least partially recycled to a hydrogen recovery from which the first and second hydrogen-containing streams are obtained. A nitrogen stream and, at least partially, the first hydrogen-containing stream are supplied to an ammonia reactor assembly for at least partial conversion into ammonia and, at least partially, the second hydrogen-containing stream is supplied to a methanol reactor assembly for at least partial conversion into the methanol.
