integrated air separation and power generation and installation for putting into practice a method of this type procedure.

摘要

Integrated air separation produces an oxygen-enriched fluid and possibly a nitrogen-enriched fluid in a plant comprising at least two apparatus for separating air (1, 101), each comprising at least two distillation columns procedure, a first air compressor (13), a first combustion chamber (17) and a first expansion turbine (19), wherein the compressed air is supplied to the first separation unit air (1) by at least first air compressor which also provides compressed air to the first combustion chamber, at least one auxiliary compressor (21, 121) provides compressed air to the second separation unit air (101), receiving the second separation unit air air treated with at least one compressor (13, 15) which also feeds a combustion chamber, there is a smaller percentage of the total air treated in the second apparatus from the compressor (13, 15) that aliment a combustion chamber, the percentage of treated air in the first device that comes from the first air compressor, or coming from both the first air compressor and a second air compressor (15) which also feeds a second combustion chamber (23), and a nitrogen-enriched (3) gas is sent from the first separation unit upstream air by at least one expansion turbine (19, 25) fed with combustion gases from at least one of the chambers combustion (17, 23).
