二氧化碳约占所有温室气体（GHG）的80%，因此成为全球变暖的主要来源，全球变暖被认为是世界面临的最大环境挑战。控制温室气体排放的努力包括从烟气中回收二氧化碳。在这项工作中，通过与工艺模拟程序 (AspenHysys) 接口的内部膜程序进行了可行性分析，以研究工艺参数对能源需求和烟气处理成本的影响。一种具有促进传输机制的新型二氧化碳选择性膜已被用来从烟气混合物中捕获二氧化碳。结果表明，即使在烟气中二氧化碳浓度较低（10%）的情况下，使用促进传输膜的膜工艺在能量需求方面与胺吸收相比也是可行的，并且可以实现超过 90% 的 CO2 回收率，并且渗透物的 CO2 纯度高于 90%。不同的工艺配置显示了工艺条件对能源需求和气体加工成本的影响，以获得 90% 的回收率和 90% 的纯度。 (C) 2009 Elsevier B.V. 保留所有权利。
Carbon dioxide accounts for about 80% of all greenhouse gases (GHG) and thus becomes the major source responsible for global warming which is considered as the greatest environmental challenge the world is facing. The efforts to control the GHG emissions include the recovery of CO2 from flue gas. In this work, a feasibility analysis has been carried out with an in-house membrane program interfaced within process simulation program (AspenHysys) to investigate the influence of process parameters on the energy demand and flue gas processing cost. A novel CO2-selective membrane with the facilitated transport mechanism has been employed to capture CO2 from the flue gas mixtures. The results show that a membrane process using the facilitated transport membrane is feasible, even for low CO2 concentration (10%) in flue gas, compared to amine absorption in terms of energy requirement and it is possible to achieve more than 90% CO2 recovery and with a purity in the permeate above 90% CO2. Different process configurations are presented showing the effect of process conditions on the energy demand and gas processing cost to obtain 90% recovery and 90% purity. (C) 2009 Elsevier B.V.
