The refinery resides on 4. Used motor oil UMO is brought into the facility by semi-truck, railcar, or by barge and is re-refined through three successive distillation steps, which stripe and convert roughly 4, barrels per day of collected UMO into vacuum gas oil, asphalt extender and fuel condensate.
The final vacuum gas oil is sold into the marine diesel market, as cutter stock, and for energy recovery. The asphalt extender is utilized in roofing products, road paving applications.
The fuel condensate is burned in industrial furnaces. Distillation Process From the feed tanks, the used motor oil temperature is raised through a series of preheat exchangers and re-boilers before reaching an atmospheric flash drum where the water and light hydrocarbons are evaporated.
The vapors from the flash drum travel overhead through a condenser and are further split into water and fuel oil downstream in an oil-water phase separator. The uncondensed vapors from the flash drum are sent and oxidized in the process heater in the refinery. Refinery Reference Desk Return to the homepage.
