ABSTRACT:
There is disclosed a method and apparatus for recovering sticky tar or oil from a fluid medium, such as water or sand. The tar is first separated from the fluid medium, e.g. by an open mesh conveyor, and the separated tar is subjected to intense heating, e.g. from live flame tubes or heat exchangers using very high temperature circulating medium. This heating liquefies the tar rapidly, and the liquid tar is directed into a suitable collection tank, which may itself be provided with a heater to maintain the tar in its liquid state.
