Abstract: A process for preparing acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen, is disclosed. The process consists of separately preheating and then mixing a first input stream containing a hydrocarbon and a second input stream containing oxygen, supplying the first input stream and the second input stream via a burner block to a firing space, quenching a cracking gas obtained to produce a process water stream and a product gas stream, cooling the product gas stream in a cooling column by direct heat exchange with cooling water, depleting soot in an electrostatic filter, combining all process water streams and passing through soot channels, subjecting the combined process water stream to a cleaning operation by partial vaporization in a one-stage flash vessel to obtain a cleaned process water stream, and recycling the cleaned process water stream into the process.

Abstract: The invention relates to a continuous method for producing acetylenes and syngas by partially oxidizing hydrocarbons with oxygen. A first feed stream (1) containing one or more hydrocarbons and a second feed stream (2) containing oxygen are mixed in a ratio of the mass flows of the second feed stream (2) to the first feed stream (1) corresponding to an oxygen number of less than or equal to 0.31, said streams being heated separately from each other, and fed to a combustion chamber (FR) via a burner block (BR), the partial oxidation of the hydrocarbons being carried out in said combustion chamber, thereby obtaining a first cracked gas stream Ig. The invention is characterized in that the first cracked gas stream Ig is precooled to a temperature ranging from 100 to 1000° C. in a prequench region (H), thereby obtaining a second cracked gas stream IIg, 50 to 90% of the solids contained in the second cracked gas stream IIg are separated therefrom in a solid-gas separating device (A), thereby obtaining a solid stream If and a third cracked gas stream IIIg, the third cracked gas stream IIIg is cooled to 80 to 90 ° C. by injecting water in a total quench region (B), thereby obtaining a fourth cracked gas stream IVg and a first process water stream Iliq, the fourth cracked gas stream IVg undergoes a fine separation of solids in one or more scrubbing devices (C, D), thereby obtaining one or more process water streams IIliq, IIIliq and a product gas stream VIg, the process water streams Iliq, IIliq, IIIliq are merged into a combined process water stream IVliq, the combined process water stream IVliq is partly recirculated, as stream Vliq, into the total quench region (B) and otherwise undergoes a cleaning process, as stream VIliq, by means of a partial evaporation process, thereby obtaining a cleaned process water stream VIIliq, which is cooled by a recooling device (F), partially recycled, as stream VIIIliq, into the method, and otherwise discharged, as stream IXliq.
