#CMT# #/CMT# The method involves determining the new boiling temperature of the product in the region of the product removal, from the vapor pressure curve of the product by changing the pressure in the column (1). The pressure and the temperature of the distillation removal are adjusted to the new boiling temperature by the modified coolant flowing through the heat-exchanger (2,17,18) in the counter direction. The distillation requires non-azeotropes mixtures, an alcohol mixture, of propanediol or industrial water or sea water. #CMT#USE : #/CMT# Method for manual or automatic control of the composition or quality of one of more products removed from the head, the sump or a lateral removal point of the distillation column and cooling of distillation column. #CMT#ADVANTAGE : #/CMT# The pressure and the temperature of the distillation removal are adjusted to the new boiling temperature by the modified coolant flowing through the heat-exchanger in the counter direction, and hence ensure good quality of the head product. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of the system. 1 : Column 2,17,18 : Heat-exchanger 4 : Vacuum unit 5 : Cooling medium inlet 6 : Cooling medium outlet. |
