Operating pressure for COW is in which range?

Operating pressure for COW is in which range?

• A. 50-80 psi
• B. 110-150 psi
• C. 80-100 psi
• D. 150-200 psi

Answer: (B)

Operating pressure for Crude Oil Washing is in the 110–150 psi range. This pressure provides enough energy to atomize and propel crude oil through the spray nozzles so it reaches tank surfaces and corners, effectively dislodging stubborn residues. If the pressure is too low, the spray becomes weak and cleaning efficiency drops, leaving residues behind. If it’s too high, components like hoses and nozzles can wear faster or fail, and spray patterns can become hard to control, increasing safety risks. The 110–150 psi range strikes a balance between cleaning effectiveness and equipment safety, which is why it’s the preferred operating range.
