ABSTRACT:
A method for treating an emulsion of hydrocarbons and solids such as sludge includes spraying the sludge into a preheater and pneumatically conveying it by primary air into an oxidation chamber. Secondary air is directed into the oxidation chamber through a plurality of perforations in the wall of the oxidation chamber to combine with and sustain the fluidized state of the solid-gas mixture. The primary air is preferably produced by passing the proceeds of an air blower through a preheater to produce hot air. The oxidizer is arranged at an incline so that the gas solid mixture of hot air and contaminated soil flows upwardly. The temperature of the fluidized bed is controlled by the temperature of the primary air so that lighter hydrocarbons spontaneously ignite in the oxidation chamber. The exothermic combustion causes the remaining organic material present in the contaminated solids to vaporize and burn. The product of this process, termed flash oxidation, is a mixture of treated solids, excess hot gas and gaseous and solid oxidation products. This mixture is separated such as by one or more cyclone separators to produce treated solids and process gas.
