    摘要： The invention relates to a method for producing acetylene and synthesis gas by partially oxidizing hydrocarbons by means of oxygen. In said method, a first input flow containing one or more hydrocarbons and a second input flow containing oxygen are preheated separately from each other, mixed at a ratio of the mass flow rate of the second input flow to the mass flow rate of the first input flow corresponding to an oxygen number λ less than or equal to 0.31, and fed via a burner block to a combustion chamber. The hydrocarbons are partially oxidized in the combustion chamber. A cracked gas is thereby obtained, which is quenched to 80 to 90 degrees Celsius downstream of the combustion chamber by injecting an aqueous quenching medium. A process water flow I
    liq and a product gas flow I
    g are obtained. The product gas flow is cooled down in a cooling column by means of direct heat exchange with cooling water in order to obtain a process water flow II
    liq as a bottom flow, a product gas flow II
    g as a top flow, and a side flow, which is depleted of soot in an electric filter. A process water flow III
    liq arises in the electric filter. The process water flows I
    liq , II
    liq , and III
    liq are merged and conducted via soot grooves having surface particle separators in order to obtain a merged process water flow IV
    liq . The method is characterized in that the merged process water flow IV
    liq is subjected to cleaning by means of partial evaporation in a single-stage flash tank, the merged process water flow IV
    liq being evaporated to a fraction of 0.01 wt% to 10 wt%, in relation to the total weight thereof, in order to obtain a cleaned process water flow V
    liq , which is recycled into the method.
