摘要：

The technical and commercial feasibility of carbon dioxide (CO2) capture with sequestration (CCS) in a geologic formation adjacent to PacifiCorp's Hunter Plant was evaluated. This includes the development of expected performance, and capital and operating costs associated with implementing CCS on Unit 3 at the Hunter Plant that burns low-sulfur, sub-bituminous coal. This study effort also includes the evaluation of multiple capture levels using a commercially available amine-based system as the basis for the capture technology. The system design and costs were developed based on the Mitsubishi Heavy Industries' (MHI) KM-CR Process (R) with KS-1(TM) solvent. Due to economies of scale, the overall cost of capture ($/ton of CO2 removed) is less at larger capture rates. The cost of capture ranges from $50, $61, $74/ton CO2 removed for 90%, 65% and 1000 lbs/MWh,g of CO2 capture from Hunter 3 with the CO2 purity greater than 95%.
