DISTILLATION DEVICE COMPRISING COLUMN WITH THREE OR MORE COMPARTMENTS CONFIGURED TO SEQUENTIALLY FLOW LIQUIDS THERETHROUGH, AND DISTILLATION OR EXTRACTIVE DISTILLATION METHOD USING DISTILLATION APPARATUS Russian patent published in 2020 - IPC B01D3/32 

Abstract RU 2720775 C2

FIELD: physics.

SUBSTANCE: invention relates to distillation device. Distillation device includes column (K) for separation of feed stream (1) into flow of head product (2), flow of still product (3) and optionally one or more side discharge streams, equipped with three or more compartments (I, II, III) , made with possibility of successive flow of liquid through them, wherein, at least, first compartment is built in column of column (K) for multistage heating and partial evaporation of liquid flowing through said sections, except fluid from last compartment, in appropriate evaporator unit.

EFFECT: technical result: simplicity of design, saving of energy costs.
