摘要： A method for obtaining an air product in an air separating system in which a liquid fraction is obtained from feed air and used to provide the air product and in which the liquid fraction is temporarily stored in a tank arrangement. A tank arrangement with at least two tanks is used, and the liquid fraction is fed to at least one of the tanks and/or is removed from at least one of the tanks in order to provide the air product. In the process, the liquid fraction is not fed to and removed from any one of the tanks at the same time, and the composition of the liquid fraction in a tank is ascertained prior to each removal of the liquid fraction from the tank. An air separating system is also described.

摘要： An air separation plant for obtaining product containing argon by low temperature separation of compressed, cooled feed air. The air separation plant comprises a high-pressure column, a multi-part low-pressure column having a base segment and a head segment and a multi-part crude argon column having a base segment and a head segment. An oxygen-enriched flow is obtained from part of the feed air in the high pressure column, an argon-enriched flow is obtained from part of the oxygen-enriched flow in the low-pressure column, and an argon-rich flow is obtained from part of the argon-enriched flow in the crude argon column. Liquid flow is transferred from a lower region of the head segment of the low-pressure column and from a lower region of the base segment of the crude argon column into an upper region of the base segment of the low-pressure column.

摘要： A method for obtaining an air product from an air separation plant having a distillation column system and a tank system. The tank system includes a first tank and a second tank. Cryogenic liquid is withdrawn from the distillation column system, stored in the tank system, and used as the air product. The cryogenic liquid is supplied to the first tank and withdrawn from the second tank during a first period, and is supplied to the second tank and withdrawn from the first tank during a second period. The tank system has a third tank to which cryogenic liquid withdrawn from the first tank and the second tank is transferred unheated. The air product is withdrawn from the third tank in liquid state, vaporized and discharged. Alternatively, the cryogenic liquid can be withdrawn from the third tank and stored in the liquid state in a fourth tank.

摘要： The plant is used for producing oxygen by cryogenic air separation. The plant has a high-pressure column, a low-pressure column and a main condenser. An argon-elimination column is in fluid connection with an intermediate point of the low-pressure column and is connected to an argon-elimination column head condenser. An auxiliary column has a sump region, into which gas is introduced from the argon-elimination column head condenser. The head of the auxiliary column is connected to a return flow liquid line, in order to introduce a liquid stream from the high-pressure column or the head condenser. The liquid stream has an oxygen content which is at least equal to that of air. At least one part of the crude liquid oxygen from the sump of the high-pressure column is fed to the auxiliary column at a first intermediate point.

摘要： A method and device to variably obtain argon by means of low-temperature separation. Feed air is cooled in a main heat exchanger and then conducted into a distillation column system with a high-pressure column and a low-pressure column. Argon is obtained using a crud argon column and a purified argon column. A purified liquid argon product flow is generated from an argon-enriched flow from the low-pressure column. In a first operating mode, a first quantity of purified argon product is discharged, and in a second operating mode, a reduced quantity of purified argon product is discharged. In the second operating mode, a gaseous argon return flow is drawn from the crude argon column or the purified argon column and heated in a separate passage of the main heat exchanger.

摘要： The invention relates to a transportable package for a low-temperature air separation plant which has a main heat exchanger (2a, 2b, 2c) for cooling feed air (1) and a double column (5) for separating the cooled feed air, wherein the double column (5) has a high-pressure column and a low-pressure column that are arranged above one another. The transportable package has a cold box (20, 400), in the interior of which accessories of the double column (5), in particular pipelines (7, 11, 12) and valves, are arranged, but not the double column and not the main heat exchanger, wherein the transportable package has connections for joining the pipelines to the double column and to the main heat exchanger. Moreover the invention relates to a low-temperature air separation plant and to a method for producing a low-temperature air separation plant using this transportable package.
