ABSTRACT:
Impurities or unwanted by-products are distilled off from an oily liquid by means of an ancillary stripping agent. The vaporization temperatures of the impurities and of the ancillary stripping agent lie below that of the oily liquid. Spontaneous distillation takes place in a decompressor to which the materials to be treated are supplied from a mixer or contactor. The decompressor comprises two nozzles arranged in series. In the decompressor the materials to be treated are subjected to a pressure considerably below the mixer pressure and somewhat below the separator pressure. Decomposition of the oil stream occurs in the decompressor into a non-volatile liquid phase and a vapor phase containing the ancillary stripping agent and the impurities originally in the oil feed. The mixed vapor/liquid stream enters the separator which is at a pressure which lies considerably below the pressure obtaining in the mixer.
