Abstract: A process and apparatus for treating any fluidizable solid material having a polychlorinated biphenyl contaminant absorbed or adsorbed thereon. The method and apparatus includes heating the fluidizable solids, using hot turbulent gas at a temperature in the range of 850.degree. to 2,500.degree. F. to vaporize and thereby separate the polychlorinated biphenyls from the fluidizable solids and to fluidize at least a portion of the solids. The polychlorinated biphenyl vapors are then further treated to dispose of the polychlorinated biphenyls, such as by condensing the liquid and filtering or decanting them from the condensed water.

Abstract: A process and apparatus for treating any fluidizable solid material having an organic contaminant or recoverable material absorbed or adsorbed thereon, particularly a sludge contaminated with polychlorinated biphenyl or other toxic chemicals having a boiling point of at least 110.degree. C. The method and apparatus includes heating the fluidizable solids to a temperature of at least 250.degree. F., using hot turbulent gas at a temperature, for example, in the range of 850.degree. to 2,500.degree. F. to vaporize and thereby separate the organic material, for example, the toxic chemicals from the fluidizable solids and to fluidize at least a portion of the solids. The recoverable or contaminant liquid, for example, the toxic chemicals, are then further treated to recover or dispose of the separated liquid, such as by condensing the liquid and filtering or decanting them from the condensed water.

Abstract: A process and apparatus for treating any fluidizable solid material having a dioxin contaminant absorbed or adsorbed thereon. The method and apparatus includes heating the fluidizable solids, using hot turbulent gas at a temperature in the range of 850.degree. to 2,500.degree. F. to vaporize and thereby separate the dioxin from the fluidizable solids and to fluidize at least a portion of the solids. The dioxin are then further treated to dispose of the dioxins, such as by condensing the liquid and filtering or decanting them from the condensed water.

Abstract: A method and apparatus for treating polychlorinated biphenyl contaminated sludge involves heating the sludge, using hot turbulent gas at a temperature in the range of 850.degree. to 2,500.degree. F. with a sludge residence time of about 0.5 to 2 seconds, to separate the polychlorinated biphenyls from the sludge. The particulates are subsequently removed from a PCB entraining gas stream and the PCB's are then burned in a multifuel burner. Pressurized air, fluidized PCB's, and a gaseous fuel are injected into the burning chamber at spaced points along the length of the flame in a direction generally transverse to the direction of the flame to very completely consume the fuel and PCB's.
