ABSTRACT:
A heat-sensitive liquid is dried and purified, by the degassing of sorbed gases, by means of a permeable electric heater, through which the liquid is passed, the liquid flowing first through a permeable liner presenting a flow impedance such that the degassing of the water vapour and gaseous impurities becomes significant only after the liquid has entered the body of the heater element.
