An apparatus () for the preparation of acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen is proposed. The apparatus () comprises a reactor (), wherein the reactor () comprises a burner block () with a furnace chamber for the preparation of a composition C1 comprising at least acetylene and substituted acetylene, a first scrubber () which is constructed for adding a solvent to the composition C1 to obtain a composition C2, a second scrubber () which is constructed for adding the solvent to the composition C2 to obtain a composition C3, a first stripper () 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 () 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 () 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 () which is constructed for stripping the solvent from the first scrubber () to obtain a composition C9, wherein the third striper () is connected to the second stripper () for feeding the composition C9 to the second stripper (), an apparatus () for adding a diluting gas to the composition C5, which is arranged between the first column () and the second stripper (), a second column () 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 () 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.
