Exxon Chemical Company Resins Finishing Plant, Baton Rouge, La., produces large volumes of hydrocarbon resins, which are used as adhesives ingredients. High-pressure pumps at a site 6 miles away deliver a liquid containing 50 to 62 percent resin mixed with a diluent to the plant. The liquid flows through a 6-inch pipeline to the plant's holding tanks. The plant uses pressure, vacuum, heat, and steam to vaporize the diluent, which is moved to a holding tank and reused later.
