Abstract
Taught herein are methods of integrated material processing, especially integrated processing of waste materials. According to the methods, waste materials are exposed simultaneously to two or more unit operations, and the physical phenomena associated with each of the unit operations act in concert to achieve a desired processing objective.
Claims20
A method of integrated waste material processing comprising:
- (a) mixing of a waste material with burnt lime, wherein said mixing results in an intermediate comprising from about 5% to about 50% by weight of lime hydrate, from about 2% to about 20% by weight of calcium oxide, from about 5% to about 60% by weight of solid matters, and from at most about 5% to at most about 90% by weight of water;
- and (b) milling said intermediate in a mill;
- wherein during said milling the temperature of said intermediate rises and an evaporation of water contained in said intermediate occurs.
A method of integrated waste material processing comprising:
- (a) mixing of a waste material with a reactant able to undergo an exothermic hydration reaction with said waste material, wherein said mixing results in an intermediate comprising from about 5% to about 50% by weight of hydrated reactant, from about 2% to about 20% by weight of unreacted reactant, from about 5% to about 60% by weight of solid matters, and from at most about 5% to at most about 90% by weight of water;
- and (b) milling said intermediate in a mill;
- wherein during said milling the temperature of said intermediate rises and an evaporation of water contained in said intermediate occurs.
