METHOD OF OPERATION OF GAS-VAPOR POWER TECHNOLOGICAL PLANT Russian patent published in 2002 - IPC

FIELD: power engineering. SUBSTANCE: method comes to compression of hydrocarbon gaseous material in compressor, thermochemical oxidizing transformation of material into intermediate product of partial oxidation or vapor or/and carbon dioxide conversion and expansion of intermediate product of conversion in gas-vapor turbine. In process of compression of hydrocarbon gaseous material in compressor, part of material is taken off from intermediate compression stage. The remaining part of material, after compression, is subjected to thermochemical; oxidizing conversion in form of partial oxidizing with liberation of heat. Taken off part of hydrocarbon material is also subjected, either together with partial oxidation product or without said product, to thermochemical oxidizing conversion in form of vapor or (and) carbon dioxide conversion with absorption of heat using part of heat of partial oxidation of hydrocarbon material. Hydrocarbon material partial oxidation product is first expanded in gas-vapor turbine and after intermediate expansions stage, summary intermediate product of partial oxidation and vapor or/and carbon dioxide conversion of hydrocarbon material is also subjected to expansion. EFFECT: increased economy and power output of plant. 3 cl, 1 dwg
