Abstract: ESTA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA MINIMIZAR LA CORROSION PROVOCADA POR EL HALURO DE HIDROGENO EN UN GASIFICADOR DE EXTINCION DURANTE LA REACCION DE OXIDACION PARCIAL NO CATALITICA DE UNA CARGA HIDROCARBONADA QUE CONTIENE UN HALOGENO, PARA OBTENER UN GAS DE SINTESIS QUE CONTIENE HALURO DE HIDROGENO, PARTICULAS SOLIDAS FINAMENTE DIVIDIDAS Y ESCORIAS NO TOXICAS. ESTE GAS DE SINTESIS QUE CONTIENE HALURO DE HIDROGENO SE PONE EN CONTACTO CON AGUA EN LA ZONA DE EXTINCION (14) DEL GASIFICADOR (10). EL AGUA DE EXTINCION CONTIENE UN AGENTE NEUTRALIZADOR, EN CANTIDAD EXCESIVA CON RELACION A LA QUE ES NECESARIA PARA NEUTRALIZAR LOS ACIDOS DE HALURO DE HIDROGENO PRESENTES EN EL GAS, DE MANERA QUE SE OBTENGAN SALES DE HALURO. EL AGUA EXENTA DE SALES NO ES PRACTICAMENTE TOXICA PARA EL MEDIO AMBIENTE Y SE PUEDE RECICLAR MEDIANTE EL PROCEDIMIENTO O DESCARTAR DE ACUERDO CON LA REGLAMENTACION DEL MEDIO AMBIENTE.

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: Fluoride-containing scale can be removed from metal surfaces such as titanium, titanium alloys, nickel alloys, and stainless steel by contacting the metal surfaces with an aqueous salt solution of an inorganic acid, including its hydrates. The cationic portion of the salt can be aluminum, iron and mixtures thereof. The anionic portion of the salt can be a chloride, a nitrate, a sulfate, and mixtures thereof. The contracting occurs in the absence of the addition of an acid, such as hydrochloric, nitric, or sulfuric acid. The presence of the aqueous salt solution with the dissolved fluoride scale does not accelerate or increase the normal rate of metal corrosion that can occur in the absence of the aqueous salt solution or any acidic cleaning agent.
