整体煤气化联合循环发电系统可采取燃烧前捕集CO2的方法,处理的合成气量少,能耗低,且能够实现CO2的近零排放,在CO2脱除方面具有很大的优势。文中基于AspenPlus对CO2/H2S联合脱除和分别脱除流程建立了模型,对2流程的能耗、CO2及H2S的脱除效率以及Selexol溶液的再生性能进行了分
利用Aspen plus模拟共沸精馏,利用灵敏度分析工具考察了塔板数,回流比,进料位置,进料温度等对产品的影响,结果显示:随着塔板数量的增加,乙酸乙酯的浓度逐渐增加的同时再沸器热负荷在降低,综合考虑投资成本和运行成本等问题,最终确定塔板数为13.(2)进料位置越靠近塔釜越不利于产品纯度的提高.(3)增大回流比可以有效...
A promising alternative technology to the liquid-phase sorption is to use solid sorbents for capturing CO2 by means of the pressure or temperature swing adsorption system, offering possible energy savings and stable performance. There are different classifications of sorbents; chemical sorbents that ...
