SEPARATION PROCESSES USING COLUMNS WITH PARTITION WALLS Russian patent published in 2017 - IPC B01D3/14 B01D3/32 

FIELD: chemistry.

SUBSTANCE: distillation column contains a column having an upper section and a lower section. The upper section has a vertical partition wall that divides the upper section into the first side and the second side. The first condenser is in fluid communication with the first side of the column, the second condenser - with the second side of the column. The receiving tank of the head product is in fluid communication with the second condenser. The reflux pump is in fluid communication with the receiving tank and the second side of the column. The first side is a raw material supply side or a pre-fractionation side. The second side is a side of the product output. The first condenser is a partial condenser, and the second condenser is a full condenser.

EFFECT: increasing the output of components and reducing the energy consumption.
