ABSTRACT:
The fumes from gas turbine TG are cooled by heat exchangers E1, E2, E01, E02and E03and compressed by compressors C1and C2. The cold and high-pressure fumes are depleted in carbon dioxide in treating plant10. The carbon dioxide can be injected into an underground reservoir. The fumes depleted in carbon dioxide are heated by heat exchangers E1and E2, and expanded by turbines T2, then T1. In particular, after expansion in turbine T2and before expansion in turbine T1, the fumes are heated using the heat of the fumes from compressor C2.
