The distillate which is contained in the prescrubbed vapors from the fatty acid fractionation or deodorization of oils and fats is obtained by mixture condensation in a cooling fluid fed into a principal flow of said vapors. A side flow enriched in distillate is drawn from the cooling fluid flow, liberated from the distillate and subsequently partially evaporated. The vapor formed thereby is advantageously used as a working vapor for drawing off and compressing the noncondensable gases contained in the prescrubbed vapors. The unevaporated residual fluid is cooled and used as the cooling fluid fed to the prescrubbed vapors. When an electrolyte solution is used as the cooling fluid, electrolyte loses are avoided and the dilution of the electrolyte solution caused by the mixture condensation is continuously compensated.
In a process for separating a water insoluble distillate from an aqueous vapor comprising condensing the condensable components of said vapor by mixture condensation in a cooling fluid, separating said cooling fluid mixed with said vapor into a distillate poor principal flow and a side flow enriched with distillate and cooling and recirculating said principal flow, the improvement comprising partially evaporating said cooling fluid forming said side flow after separation of said distillate to form a process vapor and feeding a cooled residue of said side flow not evaporated into a circulation path of said cooling fluid, whereby said process vapor made from said side flow is used as a working vapor for drawing off and compressing noncondensable gases contained in said aqueous vapor.
