Abstract
The invention proposes a method for producing acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen, wherein a first feedstock (), containing one or more hydrocarbons, and a second feedstock (), containing oxygen, —are preheated separately from one another, —are fed via a burner block (B) to a combustion chamber (F), in which the partial oxidation of the hydrocarbons takes place, —obtaining a cracked gas, which is quenched by injecting a quench oil downstream of the furnace body at 200° C. to 250° C., wherein —a flow of product gas Ig is obtained, which —is cooled in a burner column (BK) with further quench oil, obtaining —a flow of product gas IIg cooled to 60° C. to 90° C., which —is guided into a final cooler (SK), in which a flow of product gas IIIg, cooled to 20° C. to 50° C., is obtained by direct thermal exchange with water, as well as a flow of process water I liq —which is characterized in that the flow of process water I liq is subjected to purification by partial evaporation in a single-stage expansion chamber, wherein the flow of process water I liq is vaporized to a proportion of 0.01 percent by weight to 10 percent by weight, relative to the total weight of same, obtaining a purified flow of process water II liq which is removed in the waste water.
