Abstract:
A method for reclaiming oil by pyrolysis from waste plastic comprising:performing a dechlorination process;performing a Pyrolysis process after the dechlorination process, said pyrolysis process comprising directly heating dechlorinated waste plastic by mixing with heated sand and optionally an additive agent, and maintaining said dechlorinated waste plastic at a temperature of 350-500.degree. C., resulting in pyrolyzed products, said pyrolysis process being carried out in a plurality of mechanical agitation devices arranged in sequence so as to pyrolyze said dechlorinated waste plastic continuously; andconducting gaseous products obtained in said plurality of mechanical agitation devices in parallel to a gas/liquid separation process which follows said pyrolysis process.
