Abstract: A process for preparing methanol from carbon dioxide and hydrogen in a methanol synthesis unit and working up the reaction mixture obtained stepwise to isolate the methanol, wherein the carbon dioxide, carbon monoxide, dimethyl ether and methane components of value from the streams separated off in the isolation of the methanol from the methanol reaction stream are combusted with an oxygenous gas, and the carbon dioxide in the resultant flue gas is separated off in a carbon dioxide recovery unit and recycled to the methanol synthesis unit.

Abstract: An apparatus (10) for the preparation of acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen is proposed. The apparatus (10) comprises a reactor (12), wherein the reactor (12) comprises a burner block (14) with a furnace chamber for the preparation of a composition C1 comprising at least acetylene and substituted acetylene, a first scrubber (22) which is constructed for adding a solvent to the composition C1 to obtain a composition C2, a second scrubber (26) which is constructed for adding the solvent to the composition C2 to obtain a composition C3, a first stripper (36) which is constructed for stripping the composition C3 to obtain a composition C4 comprising the substituted acetylene, acetylene and the solvent and for separating off the acetylene, a first column (46) which is constructed for partial degassing of the composition C4 under a pressure of from 1.0 bar to 1.5 bar to obtain a composition C5 and a first amount A1 of the solvent, a second stripper (56) to which the composition C5 can be fed for stripping a composition C9 to obtain a second amount A2 of the solvent and a composition C6, a third stripper (68) which is constructed for stripping the solvent from the first scrubber (22) to obtain a composition C9, wherein the third striper (68) is connected to the second stripper (56) for feeding the composition C9 to the second stripper (56), an apparatus (72) for adding a diluting gas to the composition C5, which is arranged between the first column (46) and the second stripper (56), a second column (76) which is constructed for adding water to the composition C6 to obtain a composition C7 comprising a third amount A3 of the solvent and water and to obtain a composition C8 comprising the substituted acetylene, and a mixing condenser (82) which is constructed for adding water to the composition C8 to obtain a composition C11 comprising the substituted acetylene.A process for the preparation of acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen is further proposed.
