Abstract
Abstract
Compared with a pulverized coal power plant, the integrated gasification combined Cycle (IGCC) has several advantages, such as better environmental performance, less solid waste, lower water consumption, and capability of phased construction, to render a less expensive CO2 sequestration process. Because of these advantages, IGCC is considered as an enabling technology for clean coal processes for future power generation and transportation fuel - as well as for CO2 mitigation. By analyzing the traditional CO2 removal processes, in this study, we proposed a new generic hot/warm CO2 removal process for IGCC power plant. Our analyzed results on the newly proposed process demonstrate that, even though, higher the temperature of the hot/warm CO2 removal process is, the larger the required heat of adsorption will be. However, if the whole adsorption/desorption cycle takes place at temperature higher than the highest steam temperature in steam cycle, our analysis indicates that the process may lead to minimal electricity loss.
