ABSTRACT:
In a gas turbine process in which hot moist gas produced by combusting natural gas and injecting steam to the combustion device, the relative moisture content of the gas is reduced after the turbine by adiabatic absorption by means of an absorbent liquid the only evaporating component of which is water. The condensation heat of the aqueous steam condensed in the absorption is to a large extent conveyed to the gas the temperature of which is thereby raised. The heat is recovered by known methods for use e.g. in district heating. The diluted absorbent liquid is regenerated for example by arranging it in the heat recovery stage before the absorption in indirect heat exchange contact with the gas.
