ABSTRACT:
Water and organic low-boiling constituents in organic heat transfer fluids used to heat commercial processes are removed by introducing a gas such as nitrogen into a turbulent flow of the heat transfer fluid and separating gas which then contains low-boiling constituents from the heat transfer fluid of the heat transfer system. The gas containing low-boiling constituents may be sent to a condenser to return heat transfer fluid which also vaporizes into the gas, but to a lesser extent than the low-boilers, to the heat transfer system. The gas containing low-boiling constituents is then combusted.
