PROCESS FOR THE VACUUM DISTILLATION OF A LIQUID PRODUCT, PREFERABLY CRUDE PETROLEUM, AND A FACILITY FOR CARRYING OUT THE PROCESS

摘要

The proposed vacuum distillation process involves dividing the liquid product fed into a vessel under a vacuum into a steam/gas phase and at least one liquid fraction, removal of the steam/gas phase from the vessel using a vacuum-producing device, and subsequent division of the steam/gas phase into a gas and a liquid phase by condensation directly in the vacuum-producing device. A portion of the liquid phase is used as a liquid working medium for the vacuum-producing device. The proposed vacuum distillation facility comprises a vacuum vessel with pipes and a vacuum-producing device which includes a jet blower, separator and pump, these elements being interconnected by pipes.
