    摘要: A process is described for purifying synthesis gas by means of a pressure swing adsorption unit which is desorbed by a vacuum produced by a so-called ejector, which is driven by steam generated by a heat exchanger which uses the heat in the flue gas duct or in the useful-gas duct for the generation of steam. The pressure swing adsorption unit is operated advantageously in cyclic turns of adsorption under excess pressure, depressurization desorption and vacuum desorption and the gas desorbed by the ejector being cooled in a cooler so that the contained steam can be condensed and discharged or is advantageously returned to the feed gas for the synthesis gas production. The foreign gas desorbed by the pressure swing adsorption unit, which contains at least partly not yet consumed fuel gas, is recycled to the fuel gas. In an advantageous embodiment, the vacuum from the ejector is stored in an intermediate tank and applied to the pressure swing adsorption unit according to the vacuum desorption cycle. Also disclosed is a device for running this process.

    摘要: Process and plant for the production of synthesis gas, hydrogen and/or reducing gas by means of a primary reformer heated on the shell side, used in conjunction with a pressure swing adsorption unit for purifying the product gas, the purpose of which is to find a solution to the problem of utilising the work potential of the fuel gas from the pressure swing adsorption unit, which is used to fire the primary gas reformer. This is achieved by supplying the waste desorption gas from the pressure swing adsorption unit to the inlet side of an ejector, which is driven by a part stream of the fuel gas for the primary reformer, the waste desorption gas being admixed to a main fuel gas stream and/or a regulating gas stream, depending on the particular mode of operation.

    摘要: The invention relates to a process for the absorptive separation of NH3 and CH4 from a gas under high pressure, which at least contains NH3, H2, N2 and CH4, using a high-boiling, physically acting and regenerable solvent which contains homologues of alkylene glycol-alkyl-ether and which also may contain water, the absorbed components NH3, H2, N2 and CH4 being separated from the laden solvent in at least two further process steps at different pressure rates, thereby withdrawing at least one NH3-rich and at least one CH4-rich gas fraction from the solvent. This process is particularly suitable to be incorporated as unit in an ammonia production plant.
