Abstract

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 This is achieved by pressurizing the solids-laden quench water withdrawn from the quench chamber and admitting it to a high-pressure solids separator at a temperature substantially equal to the quench chamber temperature.
