摘要： Vacuum distillation process comprising introducing a feed which contains vapour and liquid into a distillation column (1) operating at a subatmospheric pressure, allowing vapour to rise inside the distillation column (1), allowing liquid to drop to the bottom part (2) of the distillation column (1) and passing liquid from the bottom part (2) of the distillation column (1) through a transfer conduit (5) to an external collecting vessel (9) from which a liquid stream is withdrawn, cooling the of the liquid stream and introducing part of the cooled liquid stream through conduit (17) into the liquid passing through the transfer conduit (5).
