Abstract
This Hazardous Waste Reclamation process pyrolyzes hazardous waste such as PCB (polychloro-biphenyl) in a closed system in a molten alloy, containing some aluminum, at a minimum of 800 degrees C. to form activated carbon that is recovered from the circulating exit gas stream and an impure alloy ingot containing unreacted metals and metal salts that are saleable to a metal processor as a high grade ore. The composition of the alloy may be varied to assure maximum reaction to nontoxic alloy salts that remain in the ingot.
Claims19
A hazardous waste reclamation process comprising:
- (a) charging a reactor means with an alloy metal means;
- (b) heating said alloy metal means in said reactor means to a minimum of 800 degrees C to from a molten alloy bed;
- (c) introducing at a controlled rate liquid and slurries thru a feed coil means into said molten alloy bed with outlet openings of said feed coil means near a bottom portion of said molten alloy bed and an inlet end of said feed coil means exterior of said molten alloy bed;
- (d) circulating an exit gas from said reactor means at essentially atmospheric pressure thru a separator means and back to a surface of said molten alloy bed.
A hazardous waste reclamation process comprising:
- (a) feeding a liquid waste stream underneath a surface of a molten alloy means in a reactor means, said reactor means being heated to maintain said molten alloy means at a minimum of approximately 800 degrees C.;
- (b) circulating in a closed system an exit gas from said reactor means through a separator means and back to a surface of said molten alloy means;
- (c) separating from said separator means an activated carbon formed from reactions in said molten alloy means.
A hazardous waste reclamation process comprising:
- (a) feeding solid waste material through a feed chute means to a surface of a molten alloy means in a reactor means, said reactor means being heated to maintain said molten alloy means a minimum of approximately 800 degrees C.;
- (b) circulating in a closed system an exit gas from said reactor means through an aqueous spray at an inlet of a separator and back to a surface of said molten alloy means;
- (c) drawing off from said separator an activated carbon formed from reactions in said molten alloy means.
A hazardous waste reclamation process comprising:
- (a) pyrolyzing a hazardous waste material in contact with a molten alloy means in a heated reactor said molten alloy means comprising individual metals chosen to form low energy level salts and free carbon from said hazardous waste material;
- (b) separating said free carbon from an exit gas stream from said reactor.
