Description:

The hydrocarbon recovery rate and temperature of the recovered product have shown that heating is a very small contributor to the actual mechanism of recovery. Microwave energy dissipates as a sphere around the antenna within the contaminated geologic zone. At a distance from the antenna, when the energy meets a hydrocarbon molecule at the correct energy level to be absorbed several mechanisms take place. The molecule will gain internal energy and increase its internal motion. And the energy will breaks the bonds between the hydrocarbon molecule and any contaminants; an example would be a benzene ring. These changes give the molecule energy to move. Eventually these molecules will migrate into the radius of influence at a recovery well to be produced to the surface. Past performance has proven that the volatile constituents are the first products recovered rendering the hydrocarbon less toxic to humans and the environment. In an ERI case history at a gasoline site, the BTEX constituents were removed first followed by the "pure" gasoline.
