    Abstract: A process for producing acetylene and syngas by partial oxidation of hydrocarbons with oxygen, involving: separately preheating a hydrocarbon and a oxygen-comprising input stream; mixing in a mass flow ratio of the oxygen-comprising to hydrocarbon stream at an oxygen number no more than 0.31; feeding the streams via a burner block to a combustion chamber and therein partially oxidizing the hydrocarbon(s) to a cracking gas; quenching the cracking gas to 80 to 90° C. downstream by injecting an aqueous quench medium to obtain a process water stream-1 and a product gas stream-2; cooling the product gas stream-2 in a cooling column by direct heat exchange with cooling water to obtain a process water stream-2 as bottoms, a product gas stream-2 as uppers, and a sidestream; and depleting the sidestream of soot in an electrofilter to generate therein a process water stream-3 combined with water streams-1/2 to afford the process water stream-4.
