This photo shows three of the piping systems used at the emulsion plant. Fill piping delivers finished emulsion product to any of six emulsion storage tanks. Supply piping delivers product from the tanks to the loading rack. Return/transfer piping receives product that may be returned from tanker trucks to storage tanks and can also transfer the product from one tank to another tank.
Valves in the piping are motorized and are controlled by a PLC. The valves and piping are heat traced. Heating is also controlled by a PLC.
A similar piping system is used for the three asphalt storage tanks.
