Abstract: A system includes a slurry inlet of the gasifier that receives a feedstock slurry and a gasification section of the gasifier that gasifies the feedstock slurry to produce syngas. The system includes a quench chamber to cool the syngas produced in the gasification section using a liquid feed to produce a quench blow down and quenched syngas. The quench blow down has solids produced as a by-product from gasification. The system includes a quench blowdown outlet which discharges the quench blow down and a slag sump liquid such that the solids concentration of the quench blowdown is reduced. The system includes a syngas outlet which discharges the syngas and a syngas scrubber fluidly coupled to the syngas outlet and to the quench chamber. The syngas scrubber includes a syngas inlet, a scrubbed syngas outlet, and a scrubber blow down outlet fluidly coupled to a fluid inlet of the gasifier.
