FIELD: technological processes.
SUBSTANCE: invention relates to fractional distillation of fluids and can be used in oil refining, pharmacy, production of desalinated water, alcohols. Distillatory contains metal evaporator electrically insulated pipeline with disk electrode and side holes at the lower end, which are coated with fine-pored disperser of upward steam flow. On the cover of the evaporator is installed distillation column with a top gas-cooled reflux condenser and the bottom hydros-trap of severe reflux. Trap through the valve is connected to the tank condenser communicated via drain valve with evaporator. Condenser partially filled with cold mixture of the same fractions and submerged into it coil, connected to a sealed collector of the distillate, connected via gas pipeline with free atmospheric space of condenser and circulation gas pump. Pump is connected through buffer receiver cooling of cover of the dephlegmator and catalytic re-combiner to joint chemical and insulated pipeline. Latter through the switch is connected with electric current source and a metal housing of the evaporator.
EFFECT: division of fractions with high purity and energy efficiency, preventing increase of concentration of heavy fractions.
