| 摘 要： | 降低CO2排放量、缓解温室效应,已成为国际社会的广泛共识。碳酸二甲酯(DMC)是国际公认的绿色溶剂,低温下对CO2具有良好的吸收性能,具有规模化应用的潜力。该文针对整体煤气化联合循环(IGCC)电厂燃烧前CO2的捕集过程,建立了DMC捕集CO2的工艺流程,对此流程进行了模拟计算并开展了技术经济分析。计算结果显示:在96%的捕集率下每吨CO2捕集能耗约在1.3～1.7GJ的范围内,DMC捕集每吨CO2工艺成本约为200元;在考虑关键变量不确定性的情况下,其成本变化范围约180～230元/t,具有经济可行性;由于具有环境友好的特点,DMC作为燃烧前CO2捕集技术的新型吸收剂具有一定的竞争力。

| Abstract: | To reduce CO2 emissions and ease the greenhouse effect has become widespread international consensus.Due to the great solubility of CO2 at low temperatures,dimethyl carbonate(DMC) is considered as a green reagent and has the potential for large-scale applications.The CO2capture process of an integrated gasification combined cycle(IGCC) system was simulated using DMC as the physical absorbent.The techno-economic model was then developed to analyze the CO2 capture cost.The results show that the energy require... |
