| 摘要 |
<p>The invention relates to a process for minimizing evaporator scaling during the recovery of liquids and solids from the aqueous effluent discharged during a partial oxidation gasification from a gasifier (16), wherein the aqueous effluent contains ammonium chloride. The aqueous effluent is evaporated in an evaporator (106) to produce a distillate water line (110) and a line containing brine (112) with a brine concentration of about 10 to 60 weight percent. The brine can be further concentrated and ammonium chloride crystals are recovered. The distillate is recycled to the gasification reaction. No effluent discharges to the environment.</p> |
