DEVICE FOR AUTOMATIC CONTROL OF THE RECTIFICATION PROCESS WITH FULL SEPARATION OF THE COMPONENTS OF THE NUTRIENT MIXTURE Russian patent published in 2017 - IPC B01D3/42 

FIELD: machine engineering.

SUBSTANCE: device contains a rectification column, a boiler, a reflux condenser, a condensate capacity, a raw material flow sensor, a raw material sensor, a level gauge in the bottom of the column, a condensate level sensor, and a distillate flow sensor. The device contains a material balance block, whose inputs are associated with flow sensors and raw material composition. One output is connected to the input regulator of the distillate flow regulator, which stabilizes the flow of the distillate taken through the valve, and the other output is connected to the input of the function block that calculates the value of the heating steam pressure in the boiler jacket, which provides the required capacity of the boiler. The device also includes a bottom liquid level controller that generates a control action on the bottoms liquid flow valve, a column pressure sensor that transmits information to a pressure regulator that stabilizes the pressure by changing the supply of the coolant through a reflux condenser, a level regulator in a condensate tank connected to a flow valve phlegm.

EFFECT: improving the quality of control of the distillate and column bottom product to the maximum possible separation of the initial mixture with significant disturbances in the consumption and composition of the raw materials.
