FIELD: processes or apparatus for separating.
SUBSTANCE: method comprises compressing air in the first compressor and separating the air into first and second portions. The first portion of the compressed air is supplied to the plant consuming the air enriched with oxygen. The second portion is cleaned in the cleaning apparatus and is supplied to the plant for air separation. The plant generates at least one flow enriched by nitrogen. At least a portion of the flow enriched with oxygen flows from the air separation plant to the apparatus that consumes the air enriched with oxygen. The air compressed in the compressor of the gas turbine is separated into the first and second fractions. The first fraction flows to the combustion chamber of the gas turbine, and the second fraction is compressed up to a higher pressure, is cleaned in the cleaning device, and flows to the plant for air separation.
EFFECT: reduced cost of air separation.
