    摘要： The process and the device are used to produce a pressurized gaseous product by low-temperature separation of air in a distillation system, which has at least one high-pressure column (7) and one low-pressure column (8). A process air stream is compressed in a main air compressor. At least a part of the compressed process air stream (1) is introduced (6) into the high-pressure column (7). A first air stream (10, 13, 14, 17, 18), which is formed at least by a part of the process air stream (1), is compressed to a high air pressure (11, 15), which is at least 1 bar above the operating pressure of the high-pressure column (7). A liquid product stream (21, 47) is removed from the distillation system, brought (48, 51) to an elevated pressure in the liquid state, and evaporated or pseudo-evaporated with the first air stream (17) under this elevated pressure by indirect heat exchange (4), and finally drawn off as a gaseous product stream (50, 53). The first air stream (17) is condensed or pseudo-condensed in the indirect heat exchange (4). The first air stream (18) is evaporated downstream from the indirect heat exchange (4) with the product stream (49, 52), which is pressurized in the liquid state, in indirect heat exchange (20) with a gaseous stream (41) from the upper section of the high-pressure column (7). The evaporated first air stream (22) is recycled (23, 26) into the process air stream (1, 2). The evaporated first air stream (23) is compressed in a recompressor (24) upstream from where it is recycled into the process air stream.

    摘要： 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).

    摘要： For obtaining gaseous nitrogen by low-temperature separation from air, a distillation column system has a single column (4). Compressed air (1) is cooled in a main heat exchanger (2) and fed (3) to single column (4). A nitrogen-rich fraction (5, 7, 8) is drawn off from the distillation column system and compressed at least in part in a circulation compressor (9, 1063). A first part (12, 13) of nitrogen-rich fraction (5, 7, 8) is fed downstream from circulation compressor (9) to the liquefaction chamber of a condenser-evaporator (14) and is condensed under a pressure higher than the operating pressure of single column (4), so to form nitrogen-rich liquid (15, 16). A liquid oxygen-enriched fraction (231) from the distillation column system is at least partially evaporated in the evaporation chamber of condenser-evaporator (14). A first oxygen-enriched gas (234, 533) formed in the evaporation chamber of condenser-evaporator (14), is introduced into single column (4). A second portion (19, 20, 1064) of the nitrogen-rich fraction (5, 7, 8) is drawn off at least at times as gaseous nitrogen product. A second oxygen-enriched gas (221, 521) is removed from the evaporation chamber of condenser-evaporator (14), work expanded (23), and heated in main heat exchanger (2).

    摘要： For producing ultrapure nitrogen by low-temperature fractionation of air in a rectification system having at least one rectification column, compressed and purified feed air is conducted into a high pressure column, an oxygen-free pressurized nitrogen fraction is produced from the high pressure column, conducted into a low-pressure column and in the low-pressure column carbon-monoxide-free low-pressure nitrogen is produced as overhead gas. The oxygen-free pressurized nitrogen fraction (1) is either taken off in the liquid state from an upper region of the high pressure column or is provided from a liquid tank (22) containing stored oxygen-free nitrogen and the oxygen-free pressurized nitrogen fraction (1) is expanded into the bottom-heated low-pressure column (2). Ascending vapour in the lowpressure column (2) by mass transfer with and an ultrapure nitrogen reflux applied at the top of the low-pressure column (2) and is freed from carbon monoxide using ultrapure nitrogen, withdrawn as carbon-monoxide-free overhead gas (5) at the top of the low-pressure column (2). After a pressure increase the overhead (5), is partially liquefied, and the liquefied part (17, 18) is expanded into a bottom-heated He—Ne—H2 column (4) from which the ultrapure nitrogen (19) is withdrawn in the liquid state.

    摘要： Apparatus for a video navigation plotter with electronic charting, specifically such a plotter designed for marine use, and various methods for processing navigational data therein and displaying resulting navigational data thereon are disclosed herein. Specifically, this plotter stores coastline data only for those cells which contain coastline data within a given geographic region of a pre-defined chart. The data for each of these cells is stored in a unique data structure that stores data for a plurality of line segments that, when drawn, collectively depicts the geographic data stored within that cell. Each segment is stored in terms of coordinate locations for a starting point followed by coordinate offset values for each successive point in that cell. Only those cells and their constituent segments are drawn for coastline data that exists within a specific region to be displayed. Once a coastline chart is displayed, the inventive plotter permits navigational data to be overlaid thereon and through this capability provides several useful features as set forth herein.
