Abstract:
A method for vacuum distillation includes separation of a liquid product delivered to a reservoir under vacuum into a vapour-gaseous phase and at least one liquid fraction, withdrawal of the vapour-gaseous phase from the reservoir using a vacuum-creating device, and subsequent separation of the vapour-gaseous phase into gas and a liquid phase by condensing performed directly in the vacumm-creating device. A portion of the liquid phase is used as a fluid working medium in the vacuum-creating device. An equipment for vacuum distillation includes a reservoir under vacuum conditions equipped with mains and a vacuum-creating device, which comprises an ejector, a separator and a pump, interconnected by mains.
