Economic Analysis of a Semi-closed Gas Turbine/Combined Cycle (SCGT/CC) with CO_2 removal by amines absorption

摘要

The Semi-Closed Gas Turbine Concept was introduced by several authors [Facchini et al., 1996 a&b] with the aim of facilitating the removal of CO_2 from the products of combustion within a gas-turbine based power plant. In fact, traditional, open-cycle gas turbines operate with large dilution of combustion products, and for large power station applications they use natural gas as a fuel: this results in a CO_2 mass fraction in the exhaust typically ranging between 4 and 6
