摘　　要：廊坊IGCC热电联供项目主体方案分别对大同混煤采用干法粉煤气化技术(以Shell为代表)和湿法水煤浆气化技术(以GE为代表)进行了研究。技术方案研究重点对这2种气化技术的CCS系统配置进行研究,推荐了小规模试验时合适的抽气点。对Shell废锅流程合成气和GE废锅流程合成气所适用的变换工艺进行了分析,推荐了合适的变换工艺为低汽气比变换技术和NHD脱硫脱碳净化技术。最后对所设计的IGCC+CCS流程进行了建模分析,研究发现IGCC电厂采用CCS系统后对效率的影响是:脱碳后Shell方案比GE方案发电效率、供电效率的降低幅度大,但其发电效率和供电效率仍然高于GE方案,只是高的幅度要低于不脱碳时的数值。To determine the main scheme of Langfang IGCC heat-electricity coordinated supply,taking Datong coal as sample ,investigate the dry process pulverized coal gasification technology（represented by Shell） and wet process coal water slurry gasification technology （represented by GE）. The CCS system configurations of these two technology have been studied, also have determined the suitable extraction point in small-scale tests. Analyze the shift process applied to Shell and GE full heat recovery process syngas, recommend a suitable shift process for low vapor-gas ratio shift technology and NHD decarbonization and desulfurization purification technology. Finally, analyze the model of IGCC ＋ CCS process,the impact of CSS system on efficiency of IGCC power plant is analyzed,the power generation and power supply efficiency of Shell program decline more than that of GE program after decarbonization, but the former is still higher than the latter,just the scale of height is lower compared to no decarburization.
