Abstract

A method of separating a high boiling component from a mixture containing organic and/or inorganic boiling components which method involves providing an induction heated screw conveyor having an auger and passing the mixture through the induction heated screw conveyor while inductively heating the auger so as to heat the mixture in the induction heated screw conveyor. The mixture is heated to a temperature that is sufficient to cause the boiling component(s) to separate from the mixture as a vapor and the boiling component is removed from the induction heated screw conveyor.

Claims (11)

1. A method of separating a boiling component from a mixture containing a high boiling component which method comprises:

providing an induction heated screw conveyor having an auger; passing the mixture through the induction heated screw conveyor while inductively heating the auger so as to heat the mixture in the induction heated screw conveyor primarily from the center of the induction heated screw conveyor;

allowing the boiling component to separate from the mixture as a vapor; and

removing the separated boiling component from the induction heated screw conveyor,

wherein at least one of the boiling component and the high boiling component has a boiling temperature of up to 750° F.

2. A method of separating a boiling component from a mixture containing a high boiling component according to claim 1 , wherein the high boiling compound comprises an organic.

3. A method of separating a boiling component from a mixture containing a high boiling component according to claim 1 , wherein the high boiling compound comprises an inorganic.

4. A method of separating a boiling component from a mixture containing a high boiling component according to claim 1 , wherein the mixture comprises a solid phase.

5. A method of separating a boiling component from a mixture containing a high boiling component according to claim 1 , wherein the mixture comprises a waste material.

6. A method of separating a boiling component from a mixture containing a high boiling component according to claim 5 , wherein the mixture comprises a refinery waste.

7. A method of separating a boiling component from a mixture containing a high boiling component according to claim 5 , wherein the mixture comprises a hazardous waste.
