<p>A system for separating hydrocarbons from a material which includes a process chamber (103), a process pan (102) operatively connected to the process chamber and removable therefrom, a blower operatively connected to the process chamber and to a heat source (112), the blower adapted to force heated air into the process chamber through the material disposed on the process pan (102), the forced heated air adapted to vaporize hydrocarbons and other contaminants disposed on the material, and at least one condenser (110) operatively connected to the process chamber (103) and adapted to condense the vaporised hydrocarbons and other contaminants is disclosed. Further, a method for separating hydrocarbons from a material which includes passing a stream of heated air over the material to volatilize the hydrocarbons, passing the stream of heated air containing the hydrocarbons through at least one condenser (110) to form liquid hydrocarbons, collecting the liquid hydrocarbons, and recirculating the heated air is disclosed.</p> |
