CIRCULATION OF PROCESS WATERS IN ENTRAINED-BED GASIFICATION UNDER PROCESS PRESSURE WITH A PRESSURE FILTRATION UNIT

摘要

An apparatus and a method for circulating process waters from plants of dust-pressure or entrained-flow gasification of solid and liquid fuels are provided, wherein process waters are separated from solids or reduced in their solids content by a pressure filtration unit under process pressure and returned to consumer loads, such as raw gas quenching processes and scrubbing processes.
