Abstract: A piping module is described which comprises at least two fluid connections or ports for connection to at least one main heat exchanger of an air fractionation plant, whereby the main heat exchanger becomes linked to at least two fluid lines in a warm part of the air fractionation plant. The piping module comprises at least two ports on the main compressor side, couplable to at least two fluid lines in the warm part of the air fractionation plant, and at least two ports on the main heat exchanger side, couplable to at least two fluid ports of the at least one main heat exchanger, and at least two fluid lines connecting the ports on the main compressor side to the ports on the main heat exchanger side. A corresponding air fractionation plant and a method for erecting such an air fractionation plant (100) are likewise described.

Abstract: The invention relates to an apparatus for the low-temperature separation of air and comprises a main heat exchanger (6) having at least two heat-exchanger blocks, a distillation column system for nitrogen-oxygen separation (5) having at least one high-pressure column, a subcooling-counterflow heat exchanger (2), means for introducing feed air via the main heat exchanger (6) into the high-pressure column, means for introducing a liquid stream from the distillation column system into the subcooling-counterflow heat exchanger (2), and means for introducing a gas stream (16) from the distillation column system into the subcooling-counterflow heat exchanger (2). The main heat exchanger (6) and the subcooling-counterflow heat exchanger (2) are arranged in a first cold box (12), and the subcooling-counterflow heat exchanger (2) is suspended from the main heat exchanger (6).

Abstract: 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.

Abstract: An apparatus and process for producing gaseous oxygen under elevated pressure utilize a distillation column system which has a high-pressure column (106), a low-pressure column (107) located above the high-pressure column (106), and a side condenser (102), which has a liquefaction space and a vaporization space, used to vaporize a liquid oxygen fraction from the low-pressure column (107). The side condenser (102) is located below the high-pressure column (106).
