METHOD FOR DISTILLATION OF MULTI-COMPONENT LIQUIDS Russian patent published in 2011 - IPC C02F1/16 

FIELD: chemistry.

SUBSTANCE: invention relates to methods for distillation of multi-component liquids and can be used in distilling oil into components (benzene, kerosene, naphtha etc), while obtaining pure alcohol (ethyl or methyl alcohol) from washing on hydrolysis plants, as well as in chemical industry for separating liquids with different boiling points and in food industry. The liquid is heated in a vapour generator by bubbling water vapour coming from outside through a layer of rotating liquid with condensation of water vapour and increase in temperature of the liquid to temperature higher than the boiling point, with reduction of pressure and formation of secondary vapour from the liquid and condensation of that vapour. The formed secondary vapour is fed into a distillation column with multiple shelves with bubble cap or sieve trays.

EFFECT: simple technique of evaporating liquid with improvement of the quality of the end product, low power consumption, high efficiency, low labour input in operating and repairing the equipment.
