Abstract: A method for operating an exhaust burner with a secondary air system downstream of a combustion engine of a motor vehicle. The method includes: activating an ignition device as a function of a release condition, the ignition device being heated up to a specifiable target temperature; metering fuel at a first time point into a combustion chamber of the exhaust burner at a first injection frequency using an injection valve, and the combustion chamber not being actively supplied with air; setting a first target air-mass flow using a secondary air system at a further, second time point, wherein the air-mass flow is increased strictly monotonically; controlling the air-fuel ratio to a first target air-fuel ratio as a function of a lambda sensor starting from the second time point, and metering fuel at a second injection frequency; setting a second target air-mass flow at a further, third time point.

Abstract: The invention relates to a method for a low-temperature air separation in which an air separation unit is used comprising a first rectification column and a second rectification column. The first rectification column is operated at a first pressure level, and the second rectification column is operated at a second pressure level below the first pressure level.

At least one fraction of the fluid which has been drawn from the first rectification column in the form of the one or more first material flows is heated in a heat exchanger; a fraction of the fluid which has been heated in the heat exchanger is compressed using a compressor and is returned to the first rectification column.

Abstract: 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).

A fluid (3) that contains oxygen and argon is introduced into first subsection (6). A stream (13) that contains oxygen and argon with an argon concentration of between 15% and 50% is removed in second subsection (7).

A liquid (38, 39, 40, 41) from the lower or middle region of the mixing column is introduced into the distillation column system.

Abstract: The process and device are used to obtain a compressed product by low temperature separation of air in a rectification system which has a pressure column and a low pressure column. A first flow of compressed and purified feedstock air is cooled in a main heat exchanger system and is fed into the pressure column.

A gaseous top product is removed from the upper area of the mixing column. A product fraction is removed from the rectification system, liquid-pressurized, vaporized in indirect heat exchange with the gaseous top product of the mixing column and is withdrawn as the compressed product.

Abstract: 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).

Abstract: 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).

Abstract: The process and the apparatus are used for the low-temperature fractionation of air in a three-column system which has a high-pressure column (5), a low-pressure column (7) and a medial column (6). Charge air (1, 2, 4) is introduced into the high-pressure column (5), where it is separated into a first oxygen-enriched liquid and a first nitrogen fraction (16). At least a part (19) of the first nitrogen fraction (16) is condensed in a first condenser/evaporator (8) to form a first liquid nitrogen fraction (20). A first oxygen-enriched fraction (22) from the high-pressure column (5) is introduced into the medial column (6), where it is separated into a second oxygen-enriched liquid and a second nitrogen fraction (24). At least a part of the second nitrogen fraction (24) is condensed in a second condenser/evaporator (25) to form a second liquid nitrogen fraction (26) and is added as reflux to one of the columns of the three-column system and/or is obtained as liquid product (64).
