Abstract:
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.
Abstract:
The invention relates to a device (10) for producing acetylene and synthesis gas by partially oxidizing hydrocarbons by means of oxygen, which device comprises a mixing unit (12), a mixing section, and a mixing diffuser (16). The mixing unit (12) has a feed opening (18) for feeding a hydrocarbon-containing flow, a feed opening (20) for feeding an oxygen-containing flow, a swirl register, and a distributor plate (24). The distributor plate (24) is arranged between the mixing section (14) and the feed opening (18) for feeding a hydrocarbon-containing flow. The distributor plate (24) has openings (28). The swirl register (22) is arranged between the feed opening (20) for feeding an oxygen-containing flow and the mixing section (14). The mixing diffuser (16) is connected to the mixing section (14). The invention further relates to a method for producing acetylene and synthesis gas by partially oxidizing hydrocarbons by means of oxygen.
Abstract:
The invention relates to a process for the parallel preparation of hydrogen, carbon monoxide and a carbon-comprising product, wherein one or more hydrocarbons are thermally decomposed and at least part of the pyrolysis gas formed is taken off from the reaction zone of the decomposition reactor at a temperature of from 800 to 1400°C and reacted with carbon dioxide to form a gas mixture comprising carbon monoxide and hydrogen (synthesis gas).
Abstract:
The invention relates to a method for the parallel production of hydrogen and of one or more carbon-containing products. In the method, hydrocarbons are introduced into a reaction chamber (R) and are thermally decomposed into carbon and hydrogen in the presence of a carbon-rich granulated material (W). The invention is characterised in that at least a portion of the thermal energy necessary for the decomposition of the hydrocarbon is introduced into the reaction chamber (R) via a gaseous heat transfer medium.
