摘要
乙醇精馏装置是将纯度为95%的乙醇经三重精馏生成无水乙醇的生产工艺。该工艺属于间歇反应,控制系统若采用PLC多回路串级调节,可以提高系统的控制精度和自动化水平。实践结果表明,由于PLC组态控制灵活、接口功能丰富、参数设置方便,操作界面直观,将在精馏装置中得到广泛应用。
The ethanol rectification device is the plant in which 95% ethanol is thrice rectified to make it anhyorous etnanol.The process is a batch reaction, the control system uses PLC multi--loop of the series--wound adjustment, to improve the precision of control and the automation. The advantages such as flexible control of PLC, multiple functions, the convenient key technical parameters setting and the open-- and--shut interface of the operating system etc. Will finally make it applied extensively in the ethanol rectification device.
