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 (NH.sub.4 Cl). The aqueous effluent is evaporated to produce a distillate water and a brine having an NH.sub.4 Cl 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 nickel content of a waste water stream, such as a stream of grey water that is separated in the decanting operation of a partial oxidation process or blow-down water from a gas quench cooling and/or scrubbing operation is reduced to below 1 mg/l to produce an environmentally upgraded water stream. In the process, the dilute waste water stream containing nickel impurities at a temperature in the range of about 60.degree. to 220.degree. F. is mixed with a water soluble material selected from the group consisting of formaldehyde, ionizable polysulfide salt, and hydrogen peroxide; and with dimethyl glyoxime. The pH is adjusted to a value in the range of over 7 to 11 by the addition of a base material and a water insoluble nickel precipitate forms. The precipitate and other insoluble matter are separated from the water by means of at least one conventional solids-liquid separator, and a stream of upgraded water is produced. At least a portion of the upgraded water stream may be recycled to the gas quench cooling and/or scrubbing operation. The nickel content of the upgraded water stream has been reduced to conform with environmental regulations. Further, build-up of nickel in the recycle circulating water system and the formation of troublesome nickel carbonyl are prevented.

Abstract: A method for processing wastewater is provided. The method includes pretreating a flow of the wastewater using at least one of a softening/clarification system, a sludge handling system, a filtration system, and an ammonia stripping system, evaporating the pretreated flow to produce at least a distillate and an evaporator brine; separating the evaporator brine to produce a liquid recycle stream and salt crystal mixture; and channeling the liquid recycle stream to a feed stream. The method eliminates the salt drying process that significantly reduces the costs of construction and operation of the standard zero process water discharge process.

Abstract: A gasifier for partially combusting a carbonaceous fuel mixture in the combustion chamber of the gasifier. The latter includes a water bath into which the hot effluent or products of combustion are immersed, including a synthetic gas. The products of combustion are directed into the bath by way of a constricted throat section. To avoid excessive erosion action and/or thermal shock to the throat section as a result of exposure to the effluent's high temperatures, the throat section is structured with an internal framework of pipes. The framework is communicated with a pressurized source of a cooling fluid, preferably water, whereby to cool the throat section sufficiently to counteract the ill effects of exposure to contact with the high temperature effluent.

Abstract: A hydrogen blistering corrosivity meter includes a cavity filled with a monitoring liquid. A liquid to be tested is separated from the monitoring liquid by a steel membrane. A device, which allows the volume of the measuring liquid to be monitored, is connected to the cavity. Dissolved hydrogen atoms, if any, formed by the test liquid diffuse through the steel membrane and enter the cavity, forming molecular hydrogen and causing an increase in volume in the measuring liquid which corresponds to the rate of corrosion activity.
