集成氧离子传输膜的CO_2零排放IGCC系统研究
|
摘要
为进一步降低从整体煤气化联合循环(IGCC)系统中捕集CO2的能耗,研究了一个集成氧离子传输膜(oxygen ion transport membrane,OTM)的富氧燃烧法低能耗捕集CO2的IGCC系统。利用Aspen Plus软件对系统进行了模拟,并对新系统与采用深冷空分的富氧燃烧法捕集CO2的IGCC系统及不回收CO2的IGCC系统进行了比较研究,并分析了OTM原料侧压力、渗透侧压力以及OTM运行温度对新系统性能的影响。研究结果表明:与采用深冷空分的富氧燃烧法捕集CO2的IGCC基准系统相比,集成OTM的新系统效率高出1.88个百分点,比传统不回收CO2的IGCC系统效率下降了6.67个百分点。
To further reduce the energy consumption of CO2 capture in IGCC system, based on the oxy-fuel combustion method, a zero CO2 emission integrated gasification combined cycle(IGCC) system with low energy consumption integrated with the oxygen transport membrane(OTM) was studied. By utilizing the Aspen Plus software, this paper compared the performances of the new system, the IGCC system with CO2 capture based on the oxy-fuel combustion method using cryogenic air separation and the traditional IGCC system without CO2 capture. The effects of the feed side pressure, permeate side pressure of OTM and the OTM operating temperature on the new system performance were investigated. The results show that the net efficiency of IGCC system with CO2 capture integrated with OTM is 1.88 percentage points higher than that of the IGCC system integrated with the cryogenic air separation, and is 6.67 percentage lower than that of the traditional IGCC system without CO2 capture.
