FIELD: chemistry.
SUBSTANCE: invention relates to a device for producing acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen. Device includes: a reactor equipped with a burner block with a combustion chamber to obtain composition Z1 containing at least acetylene and substituted acetylene, a first scrubber configured to mix composition Z1 with a solvent to obtain composition Z2, a second scrubber configured to mix composition Z2 with a solvent to obtain composition Z3, a first stripper for stripping composition Z3 to obtain composition Z4, containing substituted acetylene, acetylene and solvent, as well as for the separation of acetylene, a first column for partial degassing of composition Z4 at pressure from 1.0 to 1.5 bar to obtain composition Z5, composition Z10 and first portion A1 of the solvent, a second stripper, in which composition Z5 can be fed for stripping composition Z9 to obtain second portion A2 of the solvent and composition Z6, a third stripper for stripping the solvent from the first scrubber to obtain composition Z9, wherein in order to supply the composition Z9 to the second stripper, the third stripper is connected to the second stripper. Between the first column and the second stripper, there is a device for mixing composition Z5 with a diluent gas, a second column for mixing composition Z6 with water to obtain composition Z7 containing third portion A3 of the solvent and water, and also to obtain composition of Z8 containing substituted acetylene, and a mixing condenser configured to mix composition Z8 with water to obtain composition Z11 containing substituted acetylene. Also described is a method for producing acetylene and synthesis gas by the partial oxidation of hydrocarbons with oxygen.
EFFECT: use of the present invention allows the process to be carried out under normal or slightly excess pressure without using a vacuum.
