  • Method for controlling and cooling a distillation column
    Patent number: 8419903
    Abstract: The invention relates to a method for controlling, manually or automatically, the composition or quality of one or more products removed from the head, the sump or a lateral removal point of the distillation column having a built-in heat-exchanger. The method is characterized in that, by changing the pressure in the column, in the region of the product removal, the new boiling temperature of the product is determined from the vapor pressure curve of the product at said pressure and the temperature of the distillation removal is adjusted to said new boiling temperature by means of the modified coolant flowing through the heat-exchanger, preferably in the counter direction.
