摘要： A method of separating and reusing unconverted ammonia from cracked ammonia gas provided by an ammonia cracking unit is provided. The method includes introducing a cracked ammonia gas stream into a water wash column, thereby producing a clean gas stream and a water-containing effluent stream and introducing the water-containing effluent stream into a stripping column, thereby producing a cleaned wash water stream and a recovered ammonia stream. Wherein the cracked ammonia gas stream has an ammonia concentration of between 0.003 mol % and 10 mol %. Wherein the clean gas stream has an ammonia concentration of between 1 10 ppm and 2500 ppm. And wherein at least a portion of the recovered ammonia stream is used as fuel within the ammonia cracking unit.

摘要： The invention relates to a process for separating carbon dioxide from a raw hydrogen product stream to produce a hydrogen product stream and a carbon dioxide product stream. The process includes the absorption of carbon dioxide in an absorption stage in an absorption medium and subsequent desorption of the carbon dioxide from the laden absorption medium in a plurality of decompression stages. According to the invention carbon dioxide substreams withdrawn from the decompression stages are combined into a carbon dioxide total stream and compressed in a plurality of serially arranged compression stages. Each compression stage having a suction pressure value is assigned at least one decompression stage with a corresponding desorption pressure value and the number of decompression stages corresponds at least to the number of compression stages.

摘要： The invention relates to a partial oxidation reactor (POX reactor) for producing a raw synthesis gas stream by partial oxidation of a carbon-containing input stream in gaseous form, in liquid form or in solid, particulate form dispersed in a carrier liquid or a carrier gas in the presence of an oxygen-containing oxidant stream and optionally a moderator stream containing steam and/or carbon dioxide. The invention further relates to a process for producing a raw synthesis gas stream. The partial oxidation reactor according to the invention provides for introducing a cylindrical or frustoconical inlet region having a constant diameter or a diameter that is smaller on the entrance side. The inlet region is arranged upstream of a cylindrical main reactor portion and represents a bottleneck-like section since the largest diameter of the inlet region is smaller than the diameter of the cylindrical main reactor portion.

摘要： The invention relates to a process for removal of unwanted, in particular acidic gas constituents, for example carbon dioxide and hydrogen sulfide, from a crude synthesis gas by gas scrubbing with a scrubbing medium. According to the invention the flash gases obtained during the decompression of the laden scrubbing medium are supplied to a recompressor in order to recycle these to the crude synthesis gas and thus utilize them materially after the recompression. Alternatively or in addition the flash gases may also be supplied to a decompression turbine to recover refrigeration and mechanical work. If the recompressor and/or the decompression turbine are/is designed to have multiple stages, the flash gases obtained at different pressure levels are preferably supplied to a corresponding pressure level of the recompressor and/or of the decompression turbine.

摘要： A method of producing hydrogen from a hydrocarbon feedstock is provided. Wherein, at least a portion of a fuel stream comprises a superheated ammonia stream. And, at least: a first portion of a hydrogen-rich stream is combined with a shifted syngas stream prior to introduction into a pressure swing adsorber, a second portion of the hydrogen-rich stream is combined with the fuel stream prior to introduction into a steam methane reformer, and/or a third portion of the hydrogen-rich stream is combined with a hydrocarbon containing feedstock stream and a steam stream prior to introduction into a feed pre-heater. Heat integration between the ammonia vaporization and superheating steps is employed to cool process streams to minimize and even eliminate a dedicated cryogenic refrigeration system.
