The process has two major components: 1) removal of various trace components with a solvent (e.g., diethylene glycol or water) using a high-pressure scrubbing unit and 2) removal of H<sub>2</sub>S as sulfur via reaction with SO<sub>2</sub> (in the presence of a solvent mixed a small quantity of a homogeneous catalyst) at 120?C to 150?C and at any syngas pressure. During this research, data critical to developing and evaluating UCSRP-HP technology for multi-contaminant removal from syngas derived from Illinois #6 coal were obtained. In this paper, we have presented key economic evaluations of the UCSRP-HP process, including potential integrations with other technology options for CO<sub>2</sub> and hydrogen separations, for a nominal Illinois #6-coal-based 550-MW<sub>e</sub> Integrated Coal Gasification Combined Cycle (IGCC) facility with CO<sub>2</sub> capture and sequestration. GTI is exploring various options to demonstrate this technology in a pilot plant using actual syngas from a coal gasifier.</span><span></span>
