引言对现有生产装置的工艺操作条件进行最佳选择,固然可以达到改进生产的目的,但是,如果现有生产装置的工艺流程本身是不合理的,那末这种固有的技术缺陷是不能通过单纯地改变操作参数完全加以克服的。例如正丁烯的纯化系统这样一个简单的分离过程,系采用蒸镏(α)和萃取蒸镏(β)两种分离 Introduction The optimal choice of process conditions for existing production facilities can certainly achieve the goal of improving production. However, if the process flow of the existing production facility itself is unreasonable, then this inherent technical defect cannot be achieved through simple To completely change the operating parameters to overcome. For example, a simple separation process for the purification system of n-butene is based on the separation of distilled water (α) and extracted steamed bismuth (β).
