Abstract
A method of treating a hydrocarbon fluid that includes contacting the hydrocarbon fluid with an effective amount of ozone. A method for separating contaminants from a contaminated material includes supplying the contaminated material to a processing chamber, moving the contaminated material through the processing chamber, heating the contaminated material by externally heating the processing chamber so as to volatilize the contaminants in the contaminated material, removing vapor resulting from the heating, wherein the vapor comprises the volatilized contaminants, collecting, condensing, and recovering the volatilized contaminants, and contacting the volatilized contaminants with an effective amount of ozone.
