Removal of low-boiling fractions from high temperature heat transfer systems |
摘要 |
Water and organic low-boiling constituents in a organic heat transfer fluids used to heat commercial processes are removed by counter current stripping the fluid with a gas such as nitrogen. The gas containing low-boiling constituents is sent to a rectification column and 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.
