Abstract

The invention relates to a process for purifying hydrocarbon vapor consisting of at least one aromatic or one olefinic or one paraffinic compound or of a mixture thereof, this hydrocarbon vapor entraining impurities of acid or alkaline nature which consist of at least one water-soluble organic and/or inorganic substance and it also relates to a facility for performing such a process. The product obtained by the process according to the invention is characterized by an extremely high purity as regards impurities in the form of organic and inorganic compounds of the elements sulfur, nitrogen, oxygen and chlorine. To this end, an aqueous solution 7 is dispersed into the hydrocarbon vapor in a mixing zone 5 resulting in a two-phase vapor 8 laden with a mist of droplets, which is directly transferred to a condensation zone 6 in which both phases precipitate simultaneously. The condensate emulsion 9 thus formed is sent to a separation zone 10 in which the one partial liquid phase 12 of the emulsion mainly consisting of purified hydrocarbon is separated from the other partial liquid phase 15 of the emulsion mainly consisting of solution water with impurities dissolved therein.
