精馏操作型问题的讨论

Discussion on an Operation Problem of Distillation

本文针对精馏学习的难点-精馏操作型问题,提出可视性强的相图分析法和逻辑性强的数学证明法,把精馏过程从不同角度立体化地展现在学生面前,帮助学生充分理解精馏操作型问题的实质内涵,提高学生的工程观念和实践能力,激发学生的创新性思维。

Operation of distillation is difficult for college students. In this paper two approaches, analysis of phase diagram and prove of mathematics are introduced. They prove to be useful in helping the students master the nature of operation problems and upgrade the student＇s engineering concept.
