【 摘 要 】

The United States wishes to decrease foreign energy dependence by utilizing the country???s significant coal reserves, while stemming the effects of global warming from greenhouse gases. In response to these needs, Air Products has developed a patented process for the compression and purification of the CO2 stream from oxyfuel combustion of pulverized coal. The purpose of this project was the development and performance of a comprehensive experimental and engineering evaluation to determine the feasibility of purifying CO2 derived from the flue gas generated in a tangentially fired coal combustion unit operated in the oxy-combustion mode. Following the design and construction of a 15 bar reactor system, Air Products conducted two test campaigns using the slip stream from the tangentially fired oxy-coal combustion unit. During the first test campaign, Air Products evaluated the reactor performance based on both the liquid and gaseous reactor effluents. The data obtained from the test run has enabled Air Products to determine the reaction and mass transfer rates, as well as the effectiveness of the reactor system. During the second test campaign, Air Products evaluated reactor performance based on effluents for different reactor pressures, as well as water recycle rates. Analysis of the reaction equations indicates that both pressure and water flow rate affect the process reaction rates, as well as the overall reactor performance.
