摘要： An improved cryogenic separation process is provided for forming a substantially CO-free and lower hydro-carbon- free hydrogen-rich gas 13, suitable for use in producing an ammonia synthesis gas 14, from a hydrogen-containing gas stream 10 also containing carbon monoxide and lower hydrocarbon impurities, wherein the hydrogen containing gas 10 is subject to a two-stage autorefrigerated cryogenic flash treatment (60 and 80) to remove concentrated methane-containing and carbon monoxide-containing streams (11 and 12), and the thus-purified hydrogen gas 18 is passed to a nitrogen wash tower 100 in counter-current contact with liquid nitrogen 109 to form the desired hydrogen-rich product stream as an overheads 102 from the wash tower 100.

摘要： The invention concerns a method of treating a pyrogas before gas separation. The proposed method ensures highly economical operation owing to the low energy requirements for compressing the pyrogas and low consumption of cooling water. This results from the relatively low pyrogas temperature and low pressure losses during the multistage compression, which in turn results from the organisation of the processes of cooling, by contact heat exchange between the pyrogas, flushing water and an operating fluid, cooling these components with an external medium in refrigeration units and with a cold carrier in the evaporators of absorption machines, and by preliminary cooling of the flushing water in the generators of these machines. The proposed method of obtaining industrial low temperatures in a vapour compression refrigeration machine is characterised by a high refrigeration coefficient and low consumption of cooling water. This is made possible by the transfer of the heat of condensation of the refrigerant to the atmospheric air and by supercooling the liquid refrigerant before the expansion processes using an absorption refrigeration machine and exploiting the heat carried away from the pyrogas by the flushing water in the column.
摘要翻译：本发明涉及在气体分离之前处理焦糖的方法。所提出的方法由于用于压缩焦化的低能量需求和低的冷却水消耗而确保了高度经济的操作。这是由于在多级压缩期间相对较低的焦糖温度和低压力损失，这又是由于冷凝过程的组织，通过焦rog子，冲洗水和工作流体之间的接触热交换而产生的，制冷装置中的外部介质，以及吸收机蒸发器中的冷载体，以及这些机器的发生器中的冲洗水的预冷。所提出的在蒸气压缩式制冷机中获得工业低温的方法的特征在于制冷系数高，冷却水消耗低。这可以通过将制冷剂的冷凝热转移到大气中，并且通过使用吸收式制冷机在膨胀过程之前使液体制冷剂过冷，并利用柱中的冲洗水来利用从焦heat带来的热量。

摘要： A process for distillation of two materials of differing boiling points particularly propane, ethane or carbon dioxide from natural gas is described in which the conventional distillation tower is divided into a first tower (102) at higher pressure than a conventional tower and a second tower (104) at rower pressure. Liquid drawn from the first is expanded to the lower pressure through two or more stages (111,112) with cool extracted (65,62) at each stage and used to cool (65,62) gas (51) withdrawn from the top of the first tower to keep the top tray at a required temperature. Gas (19) withdrawn from the second tower (104) is compressed and cooled for return to the first tower as a reflux. The use of the cool from the expanded liquid and the use of the two towers provides an improved thermo-dynamic efficiency and avoids the use of costly turbo-expanders.

摘要： A method for removing gaseous pollutants from a polluted flue gas stream of an oil or coal-fired combustion furnace. A source of liquified combustible gas and a combustible gas-fired furnace are provided. The polluted flue gas stream is passed through a dust removal apparatus and removes flue dust from the flue gas stream so as to provide a de-dusted flue gas stream. Heat is recovered from the flue gas to generate power therefrom. The de-dusted flue gas is compressed to a pressure of at least 10 psi gauge using the generated power to at least in part compress the de-dusted flue gas. The compressed flue gas and the combustible gas are passed through at least one multi-sided heat exchanger, where the compressed flue gas is first passed through one side thereof and the liquified combustible gas in an at least partially vaporized state is passed through another side thereof. The compressed flue gas is cooled sufficiently by the combustible gas that water and at least one gaseous pollutant of NO2, SO2 and CO2 are condensed and separated from the compressed flue gas to provide reduced pollutant flue gas. Fully vaporized combustible gas is passed to the combustible gas-fired furnace and combusted to a further flue gas and the further flue gas is passed into the polluted flue gas stream.

摘要： A process for the cryogenic purification of industrial by-product hydrogen streams to recover a high yield of a high purity hydrogen product in which two or more of such by-product streams, one (27) containing detrimental amounts of non-readily condensible impurities having boiling points below that of methane, the other (19) containing by-product hydrogen gas streams which are substantially free of non-readily condensible impurities involves passing the feed streams separately through successive cooling (44, 46) and separation stages (54, 62). At each separation stage, a liquid bottom fraction containing readily condensible hydrocarbons is separated from the overhead of each of the two feed streams. Successive separations are carried out until the overhead from the stream which is substantially free of non-readily condensible impurities (but which contains a significant amount of readily condensible impurities, including methane) attains the desired degree of purity. At this point, the bottom fraction of this stream is predominantly liquid methane, and this bottom fraction (56) is used to scrub the overheads of the stream containing significant amounts of the non-readily condensible impurities.
