A method of processing an impure effluent fluid provided in two gaseous and liquid phases, respectively, for regenerating same to a pure re-usable substance, consisting in converting the gaseous phase into a liquid phase; subjecting each liquid phase separately to an independent fractional distillation for extracting said pure substance therefrom in the vapor state as an overhead product; condensing said pure substance into liquid condition, separately collecting the condensate from each fractional distillation by gathering same to form a separate storage and taking at least one part therefrom which will be cooled through heat exchange with a refrigerating fluid and jointly recovered. |
