METHOD OF CONTROL OF RECTIFICATION PROCESS OF THREE-COLUMN WASH RECTIFICATION INSTALLATION OF INDIRECT ACTION

摘要

A method of control of rectification process of a three-column wash rectification installation of indirect action includes observance of pressure of top and bottom of the epuration column of three-column wash rectification installation and the level of epurate. Pressure and level are maintained according to a proportional-integral-differential (PID) algorithm, fully by the specified installation simultaneously and continuously, which improves quality of dynamic processes.
