摘要： A product cryogenic liquid mixture comprising oxygen and nitrogen having a chosen mole fraction of oxygen is produced by expanding, typically through a valve 16, a pressurised stream of a precursor fluid mixture, which may be liquid air, having a mole fraction of oxygen greater than said chosen mole fraction, and thereby forming a vapour phase depleted of oxygen and a liquid phase enriched in oxygen. The vapour phase is disengaged from the liquid phase in a phase separator 18. A stream of the vapour phase is condensed in a condenser 22. The condensate is collected in a storage vessel 26 as the product cryogenic liquid mixture.

摘要： A stream of compressed air is purified in a unit 4 by removal of carbon dioxide and water vapour. The air is cooled by passage through a heat exchanger 6 to a temperature suitable for its rectification. The air is separated in a higher pressure rectifier 12 into oxygen-enriched liquid and nitrogen vapour. A stream of the oxygen-enriched liquid is reduced in pressure and introduced into a phase separator 42 provided with a reboiler 22 with the result that further separation takes place and a liquid further enriched in oxygen and an intermediate vapour are formed. A stream of the further-enriched liquid is separated into oxygen and nitrogen in a lower pressure rectifier 34. A stream of the intermediate vapour is condensed in a condenser 46 and is introduced into the lower pressure rectifier 34. A part of the liquid nitrogen reflux for the rectifiers 12 and 34 is formed by condensing nitrogen vapour separated in the rectifier 12 by indirect heat exchange with liquid from an intermediate mass transfer region of the rectifier 34. Another part of the liquid nitrogen reflux is formed by vaporising impure oxygen product of the rectifier 34 in a condenser-reboiler 72 by indirect heat exchange with nitrogen vapour taken from the rectifier 34.
摘要翻译：压缩空气流通过除去二氧化碳和水蒸气在单元4中净化。通过热交换器6将空气冷却至适合其精馏的温度。空气在高压精馏器12中分离成富氧液体和氮蒸气。将富氧液体流减压并引入设置有再沸器22的相分离器42中，结果发生进一步分离并形成进一步富含氧气和中间蒸气的液体。进一步浓缩的液体流在低压精馏器34中被分离成氧气和氮气。中间蒸气流在冷凝器46中冷凝并被引入低压精馏器34中。部分液氮回流整流器12和34是通过冷凝在精馏器12中分离的氮蒸气与来自精馏器34的中间质量传递区域的液体进行间接热交换而形成的。液氮回流的另一部分是通过蒸发不纯的通过与来自整流器34的氮蒸气进行间接热交换而在冷凝器 - 再沸器72中进行精馏。
