摘要： The efficiency of producing liquid products from a cryogenic air separation process using a distillation column system having at least a high pressure distillation column (902) and a low pressure distillation column (904) in thermal communication with each other and in which system the low pressure column (904) operates at a pressure of 60 to 520 kPag (9 to 75 psig) and at least 50% of the feed air is removed as a nitrogen product (130) from the low pressure column (904), said product having a nitrogen concentration of at least 95% and is a pressure of at least 60 kPag (9 psig), is improved by partially warming the nitrogen product by heat exchange (918), isentropically expanding the warmed product (920,922) and use of the inherent refrigeration of the expanded nitrogen. The refrigeration can be recovered by heat exchange (916) against a liquid stream (5) from the high pressure column (902) and/or by heat exchange (900) against the feed air (101).

摘要： A method and apparatus for argon recovery in which an impure argon stream is separated from air within a cryogenic air separation unit having an argon rejection column and a reflux type argon condenser disposed internally within the lower pressure column. An impure argon stream is subsequently recovered from the argon rejection column and purified within an integrated adsorbent based argon refining and purification subsystem to produce product grade argon. The waste stream from the adsorbent based argon refining and purification subsystem is recycled back to the argon rejection column so as to improve the argon recovery.

摘要： A process for producing a substantially oxygen-free inert gas product such as argon containing not more than one ppm by volume of oxygen and not more than 1 volume per million of water vapour comprises introducing hydrogen into a compressed crude argon gas stream which contains oxygen.
The hydrogen is added at a rate at least sufficient to meet the stoichiometric requirement for reaction with the oxygen impurity to form water vapour. The argon stream passes through a first catalytic reactor 5, in which the oxygen impurity reacts at elevated temperature with hydrogen to form water vapour. The resulting gas stream contains less than 500 vpm of oxygen. It is cooled in a heat exchanger 8 and flows into one of vessels 30 and 32. It first encounters a first layer of adsorbent 34 or 36 effective to remove water vapour therefrom, then a layer of oxidation catalyst 38 or 40 which enables residual oxygen in the argon to react with residual hydrogen to form water vapour, and finally a second layer of adsorbent 42 or 44 effective to remove the water vapour formed in the layer 38 or 40.

摘要： A method of purifying a gas stream (12) by removing oxygen from the gas stream in which the gas stream (12) is introduced into a series of electrically driven oxygen separation zones (16, 18, 20) that separate the oxygen from the gas stream (12) . Each of the electrically driven oxygen separation zones (16, 18, 20) has an electrolyte (34) that conducts oxygen ions upon the application of the voltage (38, 39, 40) to electrodes (22, 24; 26, 28; 30, 32) sandwiching the electrolyte (34) . The voltage (38, 39, 40) applied to each of the electrodes (22, 24; 26, 28; 30, 32) of the separation zones (16, 18, 20) is selected such that an ionic current induced in the electrolyte (34) within a particular zone (16, 18, 20) that is no greater than a limiting current. When voltage (38, 39, 40) is applied in such manner, the electrical power that is consumed is reduced over the power that would otherwise be consumed had a constant voltage been applied to all zones (16, 18, 20) . The gas stream (12) can be a crude argon stream (60) obtained from a crude argon column or a crude nitrogen stream (90) obtained from a pressure swing adsorption unit or a polymeric membrane unit .
