Abstract (en)

[origin: EP0354731A1] A method and apparatus for pyrolytically decomposing waste material characterized by injecting a mixture of waste and water into a plasma torch having an operating temperature of in excess of 5000 DEG C to form a mixture of product gases and solid particulate; separating the gases and particulate in a first cyclone separator into separate phases; transferring the particulate to a second cyclone separator and subjecting the particulate to a partial vacuum to separate any carryover gases from the particulate; subjecting the combined reaction chamber and carryover gases in a scrubber to a spray consisting of a caustic solution and water to eliminate any carryover particulate from the gases and to neutralize any HCl in the gases; and removing the gases from the scrubber.
