摘要： The invention relates to a method for liquefying a feed gas or cooling a feed gas at supercritical pressure, in which the feed gas mixed with a cycle gas is condensed or cooled in order to form a supercritical gas or liquid at the first pressure, the liquid at the first pressure is cooled in a first heat exchanger (E2), the cooled liquid is removed from the first exchanger and expanded up to a second pressure that is lower than the first pressure in order to form an expanded flow, at least one portion of the expanded flow is cooled in a second heat exchanger, the expanded flow is removed from the second heat exchanger (E2), said flow is split into at least two portions, including a first portion and a second portion, the first portion of the expanded flow constituting the liquefied product, the second portion and preferably a third portion being vaporized in the second heat exchanger and the thus-formed at least one cycle gas is then mixed with the feed gas and compressed in a compressor, before or after being mixed with the feed gas.

摘要： A method of separating off an N2-rich fraction from a liquefied hydrocarbon-rich fraction is described, in particular from liquefied natural gas, wherein the liquefied hydrocarbon-rich fraction, after its liquefaction and subcooling, is fed to a stripping column which serves for separating off the N2-rich fraction.According to the invention, a first substream of the liquefied hydrocarbon-rich fraction (2, 2′) is applied to the stripping column (S) as reflux, whereas a second substream of the liquefied hydrocarbon-rich fraction (3, 3′) is fed to the bottom of the stripping column (S), wherein the second substream of the liquefied hydrocarbon-rich fraction (3, 3′) has a higher temperature than the first substream of the liquefied hydrocarbon-rich fraction (2, 2′).

摘要： A cryogenic air separation process is set forth wherein, in order to provide the refrigeration necessary when at least a portion of the oxygen product is desired as liquid oxygen, LNG-derived refrigeration is used to liquefy a nitrogen stream in the process. A key to the present invention is that, instead of feeding the liquefied nitrogen to the distillation column, the liquefied nitrogen is heat exchanged against the air feed to the distillation column system.

摘要： Substantially all the nitrogen is removed from natural gas during the production of LNG, without producing mixed nitrogen/methane streams needing recycle and further processing, or requiring compression for burning as fuel, by operating both the high pressure and the low pressure multistage distillation towers of a two column cryogenic nitrogen rejection unit to produce acceptable liquefied natural gas as tower bottom products, while the low pressure tower is further operated to produce as an overhead a gas steam containing no more than about 1% methane for safe venting to the atmosphere.

摘要： with a Variable Proportion of Liquid Product In a single column distillation system for obtaining gaseous and liquid nitrogen with a variable proportions of liquid product by low-temperature separation from air, a first portion (12, 13) of nitrogen-rich fraction (5, 7, 8) is fed downstream of circulation compressor (9) to the liquefaction chamber of a condenser-evaporator (14) associated with the single column and condensed under a pressure higher than the operating pressure of the single column (4). A liquid oxygen-enriched fraction (228, 231) from the distillation column system is at least partially evaporated in the evaporation chamber of condenser-evaporator (14). A portion (18) of nitrogen-rich liquid (15, 16) from condenser-evaporator (14) is drawn off at least at times as liquid product. A second oxygen-enriched gas (221, 521) is removed from one of columns (546) of the distillation system and/or from the evaporation chamber of condenser-evaporator (14), machine expanded(23), and heated in main heat exchanger (2).
