    摘要: A high pressure combustion turbine (109) is integrated with a double column cryogenic air separation system by cooling (111,113) and purifying (115) a portion (11) of the compressed air (6) from the combustion turbine compressor (105), work expanding (118) a first portion (17) of the resulting cooled air (15), and introducing the expanded air (19) into the lower pressure column (119). A second portion (21) of the resulting cooled air (15) is further cooled (117), throttled (121), and introduced (23) into the high pressure column. A nitrogen product stream (35) is returned to the turbine combustor (101), and a portion (41) of the nitrogen product stream optionally is cooled (143,117), throttled (133), and recycled (31) into the higher pressure column (123). Preferably the higher pressure column operates at an absolute pressure which is 20% to 85% of the absolute pressure of the compressed air from the combustion turbine air compressor. Optionally oxygen-rich liquid (33) or nitrogen-rich liquid (45) withdrawn from the higher pressure column (123) during a period of low nitrogen product demand is stored, and withdrawn from storage to supplement feed to the lower pressure column (119) during periods of high nitrogen product demand. Alternatively, high purity liquid oxygen (51) is withdrawn from the lower pressure column (119) during a period of low oxygen product, stored, and withdrawn from storage during periods of high oxygen product demand to supplement oxygen product withdrawn from the higher pressure column.

    摘要: A fluid mixture is separated by distillation in which the feed (101) is prefractionated in a first column (103) having at least one separation stage (105) above or below the feed (101). When the separation stage (105) is above the feed (101), the prefractionator bottoms (125) provides feed to a second distillation column (109) operating at a lower pressure.
    When the separation stage is below the feed (101), a portion of condensed prefractionator overhead is pressurized and provides feed to a second distillation column. In both cases, no temperature in the first column (103) is greater than the highest temperature or less than the lowest temperature in the second column (109).
    The two-column system is readily combined with a high pressure column in a three-column distillation system for separating air, which is particularly useful for integration with a gasification combined cycle combustion turbine system.
