Abstract: A process for minimizing evaporator scaling during the recovery of liquids and solids from the aqueous effluent discharged during a partial oxidation gasification, wherein the aqueous effluent contains ammonium chloride (NH4Cl). The aqueous effluent is evaporated to produce a distillate water and a brine having an NH4Cl concentration of about 10 to 60 weight percent. The brine can be further concentrated and ammonium chloride crystals are recovered. The distillate water is recycled to the gasification reaction. No effluent discharges to the environment.

Abstract: The present invention relates to a system and method for oil gasification. In particular, the present invention relates to a system and method for oil gasification while reducing wastewater and costly purification systems. In one aspect of the invention, a process configuration for use with an oil gasification system is provided. The processing apparatus comprises a flash gas condensing section configured to receive flash gas from the oil gasification system. There is a vacuum pump coupled to the flash gas condensing section that is configured to extract vapor from the flash gas condensing section. The vacuum pump has a water outlet coupled to the flash gas condensing section, and a dry flash gas outlet. There is a syngas washing section having a wash water inlet, a spent wash water outlet, a cold syngas inlet and a syngas outlet. There is a syngas cooling section configured to receive spent wash water from the syngas washing section and to receive seal and flush water from the flash gas condensing section. In another aspect of the present invention a method for performing oil gasification is disclosed. The method comprises providing feedstock and water to an oil gasification system; receiving flash gas from the oil gasification system at a flash gas condensing section; extracting vapor generated by the flash gas condensing section; returning water produced by the extracting step to the flash gas condensing section; outputting dry flash gas produced by the extracting step; receiving spent wash water at a syngas cooling section from a syngas washing section; and outputting washed syngas from the syngas washing section.

Abstract: The invention relates to a process for minimizing evaporator scaling during the recovery of liquids and solids from the aqueous effluent discharged duri ng a partial oxidation gasification from a gasifier (16), wherein the aqueous effluent contains ammonium chloride. The aqueous effluent is evaporated in a n 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 crystal s are recovered. The distillate is recycled to the gasification reaction. No effluent discharges to the environment.
