SE LLEVA A CABO UNA OPERACION DE DESREVESTIMIENTO EN UN REACTOR DE OXIDACION PARCIAL EN LA QUE UNA PRIMERA PARTE PREDETERMINADA DEL REACTOR ES SELECTIVAMENTE DESREVESTIDO MEDIANTE DERIVATIZACION LIMITANDO LAS CONDICIONES DE REVESTIMIENTO DERIVATIZANTES EN UNA SEGUNDA PARTE PREDETERMINADA DEL REACTOR. EL DESREVESTIMIENTO SELECTIVO PUEDE CONSEGUIRSE MEDIANTE CONDICIONES DE OXIDACION CONTROLADA EN EL REACTOR QUE VARIAN DE UNA PARTE PREDETERMINADA DEL REACTOR A OTRA. ASI, EL REVESTIMIENTO PRESENTE EN UNA PARTE PREDETERMINADA SE DERIVATIZA Y FLUIDIZA PARA SU EXTRACCION DESDE EL REACTOR A UN INDICE SUPERIOR QUE EL REVESTIMIENTO PRESENTE EN OTRA PARTE DEL REACTOR, QUE NO ES DERIVATIZADA O SOMETIDA A CONDICIONES DE REVESTIMIENTO DERIVATIZANTES MAS LIMITADAS. LOS REVESTIMIENTOS DERIVATIZADOS PUEDEN SER DIFERENCIADOS DE ESCORIA NO DERIVATIZADA QUE NO FLUYE O ESCORIA DERIVATIZADA MAS LIMITADA QUE TIENEN UN INDICE DE FLUJO DE MASA INFERIOR QUE LA ESCORIA DERIVATIZADA EN CONDICIONES DE OXIDACION CONTROLADAS. LA ESCORIA DERIVATIZADA PUEDE SER EXTRAIDA SELECTIVAMENTE POR QUE HA CONSEGUIDO UNA TEMPERATURA FLUIDIZANTE INFERIOR. A selective deslagging operation is conducted in a partial oxidation reactor wherein a first predetermined portion of the reactor is selectively deslagged by derivatization while limiting derivatizing slag conditions in a second predetermined portion of the reactor. Selective deslagging can be accomplished by controlled oxidation conditions in the reactor that vary from one predetermined portion of the reactor to another. Thus, the slag present in one predetermined portion is derivatized and fluidized for removal from the reactor at a faster rate than the slag present in another portion of the reactor, which is not derivatized or is subjected to more limited derivatizing slag conditions. Derivatized slag can be differentiated from non-derivatized slag that does not flow or more limited derivatized slag that has a lower mass flow rate then the derivatized slag at conditions of controlled oxidation. The derivatized slag can then be selectively removed because it has attained a lower fluidizing temperature.
