    Abstract: The invention concerns a method which consists in: intake (through 16) of air in an inlet of the separation plant (14), supplying (through 16) at least a fraction of the intake air from the gas turbine (2), and extracting from the separation plant (16) two gas streams (through 20, 24, 32, 36) respectively nitrogen-enriched and oxygen-enriched; detecting (through 18) a substantial decrease in the flow rate of the air fraction from the gas turbine (2), then recycling (through 28, 42), to the inlet of the separation plant (14) at least part of one of the two gas streams, thereby avoiding any major fluctuation of the intake air flow rate of said separation plant.

    Abstract: with a Variable Proportion of Liquid Product 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: The present invention relates to a process for the liquefaction of a nitrogen stream produced by separating air components, by using the combination of cryogenic distillation with improved refrigeration. Very cold liquefied natural gas (LNG) is employed as refrigerant, with the LNG currently being revaporized for transportation.Multi-stage component compression is used, with the component feed to each compression stage being precooled using sequential refrigeration from the LNG. Expander means for the coldest air component product stream provides supplemental refrigeration at the cold end beyond that which is available from the refrigerant LNG.In a preferred embodiment, the feed nitrogen stream(s) are compressed to at least 300 psi in a multi-stage compressor with interstage cooling provided by heat exchange against vaporizing LNG; the resulting compressed stream is directed into first and second nitrogen substreams, followed by further cooling of the first substream by heat exchange against vaporizing LNG and then expanding the cooled first substream to produce an expanded nitrogen substream. Condensing of the second compressed substream against both vaporizing LNG and the expanded nitrogen substream is carried out. Reducing the pressure of the condensed second nitrogen substream produces a two phase nitrogen stream. Phase separation yields a recyclable nitrogen vapor stream and a liquid nitrogen stream as product.
