摘　　要：利用全生命周期方法,以环境排放数据库为工具,结合Aspenplus流程模拟,对我国正在准备建设的400MW级整体煤气化联合循环(IGCC)电站的二氧化碳排放进行了计算。计算按2个时间序列展开:首先是IGCC的建设期-运行期-退役期的时间序列,除计算此序列各阶段的CO2排放外,还分析和列出了各阶段涉及到的各种产品要素;其次是历史序列,对每个产品要素追溯了其由资源状态转变为最终被IGCC系统利用的产品形式之前,排放CO2的历史。对最主要的产品要素,采取了追溯三代历史的做法,从而尽可能全面和详尽地获得和展现了IGCC全生命过程的CO2排放情况。计算结果表明:IGCC运行过程排放是排放的主体;计算过程中一些次要过程的简化和忽略对最终结果影响不大。Using life cycle assessment method, it essay mainly calculates the CO_2 emission of a 400MW Integrated Gasification Combined Cycle system preparing to construct in China with the help of TEAM database and aspen plus process simulation. The whole calculation is considered from two time series, one is the series of construction period-operation period-decommission period. Excepting the CO_2 emission calculation of these three periods, the paper also lists and analyzes the products included in each of the three periods. So the other time series is the history series. It casts back the history emission of each product from the raw material extraction to the completion of the product. It essay casts back three-ply the history of the key products during the second line calculation in order to get the detailed emission result of the system. From the calculation result, it can be conclude that the operation emission is the main resource of the life cycle emission of the system, and the omission of the emission of some minor processes is feasible.
