OLOA 270 is a 75-80% active material dissolved in a highly refined lubricating oil solvent. It is blended with other lubricating oil additives into additive mixtures, called packages, via a computer controlled in-line blending system at Chevron Oronite's Oak Point LA plant. The in- line blender allows rapid blending in a 'just-in-time' delivery mode of the specific additive package that has been ordered. The components are pumped continuously from their storage tanks through computer controlled valves which meter the precise delivery of the additive components into a eight inch pipe approximately 40-45 feet long. The products are pumped through mixing baffles to ensure the package is properly blended. Distribution to Chevron Oronite's US customers is done primarily by tank trucks, rail cars and drums. The top of the rail car or tank truck loading platform is opened and the product is pumped into the rail car or tank truck from a storage tank or directly from the inline blender through hard piping. The area around and under the rail car is cement with an open drain that has a steel grate on top. After the rail car or tank truck is loaded, the hose is automatically pigged to the rail car or tank truck. Using ISO 9001 procedures, spills and leaks are less than 50 grams per loading (containing a maximum of 5 to 40g of the active OLOA 270). The hose end is kept on an oily drain when not in use. Any spills or leaks are sent to the storm water system. The product is sampled from the tank truck or railroad tank car before shipment and analyzed in the laboratory to ensure the product meets physical and chemical specifications. Laboratory workers wear appropriate PPE including a lab coat and eye protection.
