Chemical company finds simple solution to sticky problem
Electronic controller retrofits for bag packers reduce maintenance and labor while improving a chemical company's fill-weight accuracy.
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. The resin goes to a heated storage tank and is either pelletized [and packed in 50-pound bags and 1,000-pound bulk containers] or bulk loaded into drums, tank trucks, or tank railcars.
