中文摘要:
      针对乙醇胺溶液(MEA)化学吸收法在实际应用中能耗高的问题,在分析传统MEA法CO2捕集工艺基础上,提出由菲涅尔式太阳能热泵和燃煤机组烟气余热共同提供再生热量的CO2捕集技术。利用Aspen Plus软件对新型MEA法CO2捕集技术模拟分析,获得具有代表性的预测结果。结果表明新型MEA法CO2捕集工艺可节约63.80%的热能,新型CO2捕集系统再生塔内的温度分布曲线更为平滑,更有利于CO2快速分离。
英文摘要:
      The technology of monoethanolamine(MEA) chemical absorption has high energy consumption in practical applications. Based on the analysis of the traditional MEA CO2 capture technology, this paper proposes a novel MEA CO2 capture technology that heat is provided by Fresneltype solar heat pump and coal fired unit gas heat recovery system. Based on the Aspen Plus software, the new MEA CO2 capture process is simulated and the representative prediction results are obtained. The results show that the new MEA CO2 capture process can save energy by 63.80%; the temperature distribution curve in tower of the new CO2 capture system is smoother, which is more conducive to the rapid separation of CO2.
