APPARATUS FOR DRYING AND CLEANING HYDROCARBON FRACTION FROM METHANOL Russian patent published in 2012 - IPC C07C7/06 C10G7/08 B01J8/00 

FIELD: chemistry.

SUBSTANCE: apparatus has a line for feeding the starting mixture, a phase separator, a line for feeding water, a separation column having a stream inlet and outlet, a condensed vapour cooler and an output for the ready product. The apparatus is also characterised by that it is fitted with a mixer connected to the line for feeding water and the phase separator, having an outlet for the water-methanol mixture and an outlet for the separated hydrocarbon liquid phase. The line for feeding the starting mixture is connected to the mixer or the outlet for the separated hydrocarbon liquid phase from the phase separator which is connected to the separation column whose bottom part is fitted with an evaporator, wherein the column or the evaporator has an outlet for the ready hydrocarbon fraction, and the vapour outlet of the separation column is connected to an additional compressor whose outlet is connected in series to the evaporator, the cooler and the mixer.

EFFECT: use of the present apparatus enables to reduce specific power consumption of the drying and purification processes.
