    摘要: A power plant and method of operation is provided. The power plant comprises at least one main air compressor (12), an oxidizer unit (62) configured to deliver a compressed oxygen-rich gas flow (24) to at least one gas turbine assembly. Each assembly comprises a turbine combustor (32) for mixing the compressed oxygen-rich gas flow (24) with a recirculated gas flow (50) and a fuel stream (28) to burn a combustible mixture and form the recirculated gas flow (50). A recirculation loop (52) recirculates the recirculated gas flow (50) from a turbine (34) to a turbine compressor (30). A recirculated gas flow extraction path (63) extracts a portion of the recirculated gas flow (50) and delivers this to a gas separation system (65). The gas separation system (65) separates the second portion of the recirculated gas flow (50) into a nitrogen portion and a carbon dioxide portion.

    摘要: The invention relates to a gas- and steam turbine unit (1) comprising a steam generator (30) which uses waste heat and is mounted downstream from the gas turbine (2) on the flue gas side. The heating surfaces of the generator are mounted in the water-steam circuit (24) of said steam turbine (20). A gasification device (132) is mounted downstream from the gas turbine (2) through a fuel duct (130) for integrated gasification of a fossil fuel (B). A saturator (150) is mounted in the fuel duct (130). Reliable operation of said saturator (150) is required for such a gas- and steam turbine unit (1) irrespective of the operation mode of said gasification device (132). In addition, a steam water-heat exchanger (184), mounted on the secondary side of said saturator circuit (132), is fed on its primary side with feeding water (S) drawn from the water-steam circuit (24) of the steam turbine (20). The feed water (S) which is cooled in the water-heat exchanger of the saturator (184) can be heated by means of a partial stream (T) of compressed air, whereby said partial stream (T) of compressed air can transferred to an air separation facility (138) mounted upstream from said gasification device.

    摘要: An integrated gas turbine/air separation system is operated at or below full system load by feeding the air separation unit (39) with air from a dedicated air feed compressor (43) and optionally with extracted air (37) from the gas turbine air compressor (3). When the gas turbine air compressor discharge (5) drops below a selected pressure at part load conditions, the flow of extracted air (37) to the air separation unit (39) is discontinued and the air separation unit (39) operates at constant pressure supplied only by the air feed compressor (43). This mode of operation is particularly useful in an integrated gasification combined cycle (IGCC) power generation system and allows the design of the oxygen and nitrogen product compressors (51,61,67) such that the compressors operate at high efficiency during full load IGCC operation.

The improvement comprises: (a) heat exchanging (148) a portion (162) of the liquid oxygen bottoms of the lower pressure column (116) against a nitrogen vapor stream (146) removed from the higher or lower pressure columns (110,116) or derived from the gaseous nitrogen product (152), wherein prior to such heat exchange the pressure of the liquid oxygen bottoms portion or the nitrogen vapor stream or both the pressure of the liquid oxygen bottoms portion and the nitrogen vapor stream is adjusted by an effective amount so that an appropriate temperature difference exists between the liquid oxygen bottoms and the nitrogen vapor stream so that upon heat exchange the nitrogen vapor is totally condensed and the liquid oxygen bottoms portion is at least partially vaporized; (b) utilizing the condensed nitrogen as reflux in at least one of the two distillation columns; and (c) warming the vaporized oxygen to recover refrigeration.

    摘要: The invention relates to a method and to a device that serve for producing compressed nitrogen by low-temperature decomposition of air in a distillation column system which has a high-pressure column (202), a low-pressure column (203), a high-pressure column head condenser (204) and a low-pressure column head condenser (205). A main air compressor (9) constitutes the only gas compressor powered by external energy. In the main air compressor (9) the feed air is compressed to a total air pressure which is at least 5 bars above the operating pressure of the high-pressure column (202). A first part-stream (56) of the high-pressure total air stream (11, 811) from the main air compressor (9) is expanded to perform work as operating pressure of the high-pressure column or a higher pressure (57) and is introduced into the distillation column system (201). A second part-stream (52, 55) of the high-pressure total air stream (11, 811) is cooled in a main heat exchanger (51) and is introduced at least partially in liquid form into the distillation column system (206, 210). An internally compressed nitrogen stream is formed by a part-stream (319) of the liquid nitrogen stream (215) from the high-pressure column head condenser (204) and/or a part-stream (234, 334) of the liquid nitrogen stream (232) from the low-pressure column head condenser (205); the internally compressed nitrogen stream is brought in the liquid state to a product pressure (235, 335a, 335b) which is between 15 and 100 bars; then the internally compressed nitrogen stream is heated in the main heat exchanger (51) and then extracted as a gaseous compressed nitrogen product (60) below the product pressure.
