摘要
在精细化工领域,通过精馏过程进行产品分离、提纯或溶剂回收时,系统经常处于非稳态过程。进料流量波动或其中轻组分含量变化,以及热源温度或压力波动,都会影响精馏塔内的物料平衡和热量平衡,因此制定合适的控制方案,对于实现系统的自动化控制至关重要。
In fine chemical industry,when distillation is applied to products separation, purification, or solvent recovery, the process is usually unstable. Fluctuation of feeding flowrate, light component composition, as well as temperature or pressure of heating source, will affect the mass balance and heat balance of the distillation column. Therefore, it is very important to establish a suitable control plan, to satisfy automatic control of the system.
