Besides a synthesis gas, a metallurgical raw material is to be produced from an oil containing heavy metals. To do this, the oil is partially oxidized and the heavy metal-containing soot is separated and burnt and the heavy metals thus occurring as ash can be taken to further processing, e.g. washing from the synthesis gas produced, using an aqueous washing solution.

Process for producing a metallurgical raw material from oil containing heavy metals

Referring to a process for the reconditioning of quench water or scrubbing water obtained as effluent from plants for the pressure gasification of solid or liquid fuels it is intended to provide for a method which eliminates the need of cooling and expanding large volumes of quench water for the purpose of solids separation. This is achieved by pressurizing the solids-laden quench water withdrawn from the quench chamber and admitting it to a high-pressure solids separator at a temperature substantially equal to the quench chamber temperature.
