Because of the environmental concerns these emissions evoke, several carbon capture technologies have been proposed and integrated into these coal power plants with the goal to reduce the CO2 emissions by at least 90%. The main process utilized for carbon separation and capture employs absorption with amine-type solvents, whereby CO2 is separated through the use of a Dual-Stage Selexol unit4.
In this work, the design of an Integrated Gasification Combined Cycle (IGCC) plant featuring membrane and adsorptive reactors is first developed and then analyzed from an economic viewpoint. The design features membrane and adsorptive reactors that have over 90% carbon capture capability without the use of a Dual-Stage Selexol unit. The resultant intensified design is able to produce power more efficiently than traditional IGCC plants with Carbon-Capture Storage (CCS) technology. The UNISIM software (Honeywell trademark) is used to create an intensified flowsheet for the proposed power production plant design, and heat integration studies are presented. A technical economic analysis (TEA) is carried out on the proposed flowsheet to determine economic feasibility of the novel design. The economics of the intensified designs will be compared to a traditional IGCC plant with CCS to identify the extent of process intensification over the baseline design.
