隔板塔虽然有显著的节能优势,但因在操作中无法控制和调节气相分割比这一重要参数,其工业应用受到了限制。为此Agrawal等提出了隔板塔的改进流程,通过增加塔段和冷凝器或者再沸器,有效避免了因气相分割比导致的局限性。Agrawal等仅用简捷法分析证明了几种新的结构和原隔板塔是等价的。用Aspen Plus软件,选用不同物系,对改进型隔板塔流程和原流程进行了严格模拟和比较,证实了改进流程和原流程的等效性。同时给出多种改进流程的塔径设计计算结果,对改进的隔板塔实际设计可行性进行了讨论。
Separator tower has significant energy saving advantages, but its industrial application is limited due to the inability to control and adjust the important parameter of gas phase partition ratio in operation. For this reason Agrawal et al. Proposed an improved process of the separator tower. By adding the tower section and the condenser or the reboiler, the limitation caused by the gas phase division ratio is effectively avoided. Agrawal et al. Used only simple analysis to prove that several new structures were equivalent to the original separator column. Using Aspen Plus software, different systems are selected to strictly simulate and compare the improved separator tower flow process and the original process, which proves the equivalence between the improved process and the original process. At the same time, a variety of calculation results of the tower diameter design process are given, and the feasibility of the actual design of the improved diaphragm tower is discussed.
