Control of the rectification column to ensure the required quality of the top product

Abstract Based on the solution of mathematical description static mode operation in distillation column, concentration and temperature profiles along height column were obtained, positions control plates determined by calculating their gradients. The sequence solving material balance equations is under assumption ideal mixing liquid plate dynamic method piecewise linear approximation. A reflux consuming scheme has been developed according to condition minimum deviation time current value (x t ) at each interval from its set value. This turn makes it possible anticipate changes for a transport disturbance “control plate-top column” provide required quality top product.
