METHOD OF PRODUCING ACETYLENE Russian patent published in 2011 - IPC C07C11/24 C07C2/78 C07C2/80 C07C2/82 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing acetylene through partial oxidation, splitting in an electric arc or pyrolysis of hydrocarbons. The reaction stream containing the obtained acetylene and soot is directed into a compressor, characterised by that the compressor used is a screw compressor, where liquid which absorbs a large amount of soot contained in the reaction stream is injected into the compressor. If water is injected, content of soot in the water coming out of the compressor is between 0.05 and 5 wt % and if other liquids are injected, the viscosity of the suspension must be comparable with the viscosity of the soot suspension in water.

EFFECT: use of the method enables to use the screw compressor for long periods without preliminary separation of soot.
