Abstract: The invention relates to a method for storing and recovering energy, according to which a condensed air product (LAIR) is formed in an energy storage period, and in an energy recovery period, a pressure flow is formed and is expanded to produce energy using at least part of the condensed air product (LAIR) without a supply of heat from an external heat source. The method comprises inter alia, for the formation of the condensed air product (LAIR): the compression of air (AIR) in an air conditioning unit (10), at least by means of an adiabatically operated compressor device (12); the formation of a first and a second sub-flow downstream of the adiabatically driven compressor device (12), said flows being formed from the air (AIR) that has been compressed in said device and the guiding of the first and second sub-flows in parallel through a first thermal store (131) and through a second thermal store (132), in which stores heat produced during the compression of the air (AIR) is at least partially stored. For the formation of the pressure flow, a vaporized product (HPAIR) is produced inter alia from at least one part of the condensed air product (LAIR). During the energy-producing expansion process, the pressure flow is guided through a first expansion device (61) and a second expansion device (62) and is thus expanded in each device. Heat stored in the first heat store device (131) is transferred to the pressure flow upstream of the first expansion device (61) and heat stored in the second heat store device (132) is transferred to the pressure flow upstream of the second expansion device (62). The invention also relates to an installation (100).

Abstract: The invention relates to a method and device for obtaining pressurized nitrogen and pressurized oxygen by low-temperature separation of air. Compressed and purified feed air is cooled down in a main heat exchanger and introduced into a distillation column system comprising at least one high-pressure column and one low-pressure column. The distillation column system for nitrogen-oxygen separation in addition contains a residual gas column operating at a pressure which is lower than the operating pressure of the low-pressure column. A liquid crude oxygen fraction from the high-pressure column (50) is expanded and passed to the residual gas column at a first intermediate point. A gaseous impure nitrogen stream from the low-pressure column is introduced into a bottoms evaporator of the residual gas column and there is at least partly liquefied. The at least partly liquefied impure nitrogen stream is expanded and introduced into the upper region of the residual gas column.
