The invention relates to a device (10) for producing acetylene and synthesis gas by partially oxidizing hydrocarbons by means of oxygen. The device (10) comprises a reactor (12), wherein the reactor (12) has a burner block (14) having a combustion chamber for producing a composition Z1 containing at least acetylene and substituted acetylene, a first scrubber (22), which is designed to mix the composition Z1 with a solvent, a composition Z2 thus being obtained, a second scrubber (26), which is designed to mix the composition Z2 with the solvent, a composition Z3 thus being obtained, a first stripper (36), which is designed to strip the composition Z3, a composition Z4 containing the substituted acetylene, acetylene, and the solvent thus being obtained, and to separate the acetylene, a first column (46), which is designed to partially degas the composition Z4 at a pressure of 1.0 bar to 1.5, a composition Z5 and a first portion A1 of the solvent thus being obtained, a second stripper (56), to which the composition Z5 can be fed for stripping a composition Z9, a second portion A2 of the solvent and a composition Z6 thus being obtained, a third stripper (68), which is designed to strip the solvent from the first scrubber (22), a composition Z9 thus being obtained, a third stripper (68), which is designed to strip the solvent from the first scrubber (22), a composition Z9 thus being obtained, wherein the third stripper (68) is connected to the second stripper (56) in order to feed the composition Z9 to the second stripper (56), a device (72) for mixing the composition Z5 with a thinning gas, which device is arranged between the first column (46) and the second stripper (56), a second column (76), which is designed to mix the composition Z6 with water, a composition Z7 containing a third portion A3 of the solvent and water thus being obtained and a composition Z8 containing the substituted acetylene thus being obtained, and a direct-contact condenser (82), which is designed to mix the composition Z8 with water, a composition Z11 containing the substituted acetylene thus being obtained. The invention further relates to a method for producing acetylene and synthesis gas by partially oxidizing hydrocarbons by means of oxygen. |
