摘要
利用新提出的塔板差分方程(Stage difference equation,SDE),分别对简单精馏塔和有侧线出料的精馏塔进行了SDE数学模型的建立和理论塔板数的设计计算。并将塔板差分方程的计算结果与ASPEN的模拟结果进行了比较,充分证明了塔板差分方程在精馏塔设计上的简便性和有效性。
Based on the stage difference equation proposed, the mathematical models and theoretical plate number for simple distillation column and distillation column with sidestream were set up and calculated respectively. The calculation results by stage difference equation ware compared with the results of ASPEN simulation. It was showed that stage difference equation was a convenient and effective method in design of distillation column.
