RECTIFICATION PLANT Russian patent published in 2010 - IPC B01D3/14 B01D3/32 

FIELD: process engineering.

SUBSTANCE: invention relates to chemical, petrochemical, food and other industries, in particular to method of separating bi- and multi-component mixes by rectification. Rectification plant comprises rectification column representing tubular-case heat exchange apparatus with tube space making column bearing section with tubular annulus making column distillation section, heat exchanger communicated with top part of tubular annulus, compressor to compress vapors, distiller communicated with top part of column concentration section, line to feed vapor-fluid mix from column bottom via heat exchanger into top part of tubular annulus, and reducer valve arranged in aforesaid line and fitted on one shaft with compressor. Tubular annulus and space inside tube are filled with packing, grid or screen is arranged nearby tube bottom edge while tube walls are corrugated.

EFFECT: higher efficiency due to lower power consumption.
