    摘要： An integrated air separation process produces an O2-enriched gas stream and an N2-enriched gas stream in an air separation unit. The N2-enriched gas stream is heated in a first heat exchanger associated with a first boiler and then power is generated from the heated gas stream. The O2-enriched gas stream is introduced with fuel to a combustor associated with the first boiler, producing flue gas. At least a portion of the flue gas exiting the first boiler is used to generate power. In a preferred embodiment, another portion of the flue gas exiting the first boiler is recycled to the first boiler, as a temperature controlling fluid.

    摘要： A method for separating air by cryogenic distillation. A first compressor compresses air to a first pressure, and sends part of that air to a second compressor which compresses that part to a second pressure. Part of the air at the second pressure is cooled in a heat exchanger and sent to a third compressor where part of it is compressed to a third pressure. Part of the air at the third pressure is liquefied and sent a column system. Around half of the total liquefied air sent to the column system will have originally been compressed by the third compressor. Part of the air at the first pressure is cooled in a heat exchanger and part of the cooled air at the first pressure is then expanded to the pressure of the column system. The expanded air is sent to the column system.

    摘要： Air is separated in a triple column comprising a high pressure column, an intermediate pressure column and a low pressure column, the intermediate pressure column being fed by oxygen enriched liquid from the high pressure column. The low pressure column feeds an argon column with argon enriched liquid and operates at a higher pressure than the argon column. Heat is supplied to the bottom of the argon column by sending gas to a bottom reboiler. This gas is preferably rich in nitrogen and may come from the top of the low pressure column.

    摘要： A method of and apparatus for separating C.sub.4 hydrocarbons from a feed comprising a gaseous mixture. The feed is cooled and partially condensed in a plurality of successive stages of condensation and phase separation. A gaseous overhead from each separation stage is further cooled and supplied to the next separation stage and the liquid separated from each stage is used to cool the gas. Further refrigeration is supplied to the gas to effect the condensations by indirect heat exchange with a closed cycle refrigerant subjected to a compression/expansion cycle. The feed undergoes no compression and no abrupt expansion during the separation, so that the feed undergoes a pressure decrease due only to friction of the passage of the feed through the apparatus. The pressure loss is no more than about 20 psi. The temperature of the feed is maintained below 150.degree. F. at all times, to prevent polymerization of 1,3-butadiene. A mixed refrigerant passes through the closed refrigeration cycle and contains, in decreasing order of plentitude, propane, ethylene, isopentane and nitrogen. The mixed refrigerant is subjected to a single compression followed by cooling and phase separation. The phases of the mixed refrigerant thus separated are separately cooled and expanded and the material thus produced by expansion is used to cool the feed.
