aspen中的萃取模块和萃取精馏模块的区别？ 萃取精馏是向精馏塔连续加入高沸点添加剂，改变料液中被分离组分间的相对挥发度，使普通精馏难以分离的液体 ... @longkui1990 看了遍化工原理，搞明白了，但是aspen中的萃取模块规定第一第二液相的关键组分时，看了帮助，大体意思是根据浓度区别关键组分， 不知道我理解的对不对？？ 下面是我从帮助里看到的 use this sheet to specify the key components used to identify the first and second liquid phases. you must identify the key components in each phase to help the phase-splitting algorithm deal with the wide range of compositions in extractors, which may include only first liquid in the top feed and only second liquid in the bottom feed. it is the concentrations of these key components, not density, that identifies the phases. 查看更多
