METHOD OF AUTOMATIC CONTROL OF ALCOHOL DISTILLATION PROCESS IN A DISTILLATION COLUMN

摘要

A method of automatic control of alcohol distillation process in a distillation column includes pressure regulation of the column top, pressure regulation of the column bottom and concentration of alcohol at outlet. To compensate for the effects on the pressure of the column bottom a corrective link is introduced that is implemented by a transfer function:where- transfer function OU on the channel «u2-Pt"; - transfer function OU on the channel «u2-Pb";- transfer function of the controller 7.
