    Purifying Used Oil Patents and Patent Applications (Class 208/179

    Abstract: A process and apparatus for re-refining used lubricating oil (ULO) having ULO is mixed with a superheated distillate which may be a recycle stream, The system adds an amount of additional liquid hydrocarbon to separate the pumping waste toward a distillation vessel; mixing waste with heated waste, and

    Pyrolysis of Waste Engine Oil in the Presence of Wood Ash

    Possible acceptable processes are distillation, cracking, and pyrolysis. The aims of waste engine oil processing are upgrading via recycling and re-refining for providing heat energy to the reactor, namely auto-thermal heating system, heated by either jacketed electric heaters [22], autoclaves, or molten salt baths [ 23].
