  • Method and a device for the control of a distillation or condensation apparatus
    Patent number: 5976323
    Abstract: The invention concerns a method and device for controlling a distillation or condensation apparatus including a distillation vessel, heat source and condenser. A distillation or condensation apparatus consumes considerable quantities of cooling water which is discharged, through a length of hose connected to the condenser, directly into the drain. The aim of the invention is to propose a method and device for controlling a distillation or condensation apparatus to ensure a significant reduction in cooling-water consumption. The method proposed achieves this by virtue of the fact that the cooling water flowing through the condenser of the distillation or condensation apparatus is passed round in a closed loop, its temperature is measured in this loop and, when an upper temperature limit is reached, cooling water is replaced by feeding in cold water until a lower temperature limit is reached.
