    Abstract: An apparatus and method for decontaminating petroleum contaminated soil and the like, and which comprises a rotary drum dryer which is adapted to convey the soil therethrough, and which includes a burner at one end for generating a heated gas stream which passes through the dryer to heat the soil to a temperature sufficient to volatilize the contaminates. A fixed enclosure is mounted to surround the discharge end of the dryer and the enclosure receives the heated soil as it is discharged from the dryer. Any entrained dust particles which are withdrawn with the exhaust gas stream from the dryer, and which may remain contaminated, are separated from the gas stream and returned to the enclosure. In the enclosure, the returned dust is mixed with the heated soil so as to cause the dust to be heated and to release its volatile contaminates, without risk of the returned dust being again entrained in the gas stream flowing through the dryer. Also, the volatilized contaminates released from the dust will be drawn back into the gas stream passing through the dryer and a significant portion thereof will be oxidized by the burner flame.

    Abstract: In a method for the combined processing for disposal of industrial, problem waste, of problem free waste and of slush as resulting from sewage treatment, wherein the problem waste is pyrolytically carbonized on a continuous, revolving basis, and wherein the resulting coke is mixed with heated acidized slush, filtered and drained. The gas developed during carbonization is washed and used as heating agent; the mixture is then mixed with problem free waste to obtain a coke-slush waste mixture and the said latter mixture is burnt.
