Abstract:
1. A process for preparing acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen, in which a first input stream ( 1 ) comprising one or more hydrocarbons and a second input stream ( 2 ) comprising oxygen are separately preheated; mixing in a ratio of the mass flow rates, the second input stream ( supplying the mixture via a burner block (B) to a combustion chamber (F) in which the partial oxidation of the hydrocarbons takes place, to obtain a cracking gas; quenching the cracking gas to 200° C. to 250° C. downstream of the combustion chamber by injection of a quench oil, to obtain a product gas stream I cooling the product gas stream with further quench oil in a burner column (BK), by drawing off liquid from one or more suitable stages in the burner column (BK), cooling it by indirect heat exchange with water to raise steam, and supplying it again to the burner column (BK) above the stage from which it was drawn off to obtain a product gas stream II passing the product gas stream II subjecting the process water stream I
