Background The major benefit of Sour PSA discovered in the techno-economic studies conducted to date is the reduction in capital cost of the acid gas removal system. Estimates from studies on H2 production for refinery applications and clean power indicate a projected savings of >14% in capital cost for purifying the syngas and producing CO2 and sulfur products. This leads to a significant reduction in the cost of CO2 capture. Based on CO2 capture case studies conducted to date, Sour PSA technology and Rectisol® and SelexolTM technologies are about the same on an operating cost basis. When producing power from a high-sulfur fuel, up to an estimated 4.5% of additional net power is produced from the plant.ii,ii The results are sensitive to the feedstocks and gasification technology employed. Recent experimental validation of the models used to predict the benefits of a large-scale, commercial plant was key to increasing confidence in the results of the studies. A long-term study of Sour PSA performance on gasified low- rank coal is essential to provide a more robust assessment of the system’s long-term performance and economic benefits when applied to syngas plants. A comparison of state-of-the-art acid gas removal technologies and the Sour PSA system is presented in Table 1.PDF Image | Air Products Pressure Swing Adsorption at the National Carbon Capture Center
