Abstract

Sorbent thermodn. modeling study and a process simulations study for an integrated gasification combined cycle (IGCC) plant with a sorption-enhanced water-gas-shift (SEWGS)-based CO2 capture unit are presented. Seven sorbents, including two metal oxides (Mg, Ca), three zirconates (Li, Ca, Ba), one silicate (Ba), and one titanate (Ba), were identified to be thermodynamically suitable for the SEWGS application. Process simulation studies revealed that net thermal efficiency of an IGCC-SEWGS was between 0.5 and 2.4% higher than an IGCC plant equipped with a conventional Selexol process for CO2 capture. on SciFinder(R)]
