In this animation, we take a closer look inside a Sour Water Stripper (SWS) and explain how it removes contaminants such as hydrogen sulfide (H₂S) and ammonia (NH₃) from refinery sour water.

The animation demonstrates the main operating principles of the stripper, including:

• Sour water feed and distribution
• Counter-current stripping with steam
• Removal of H₂S and ammonia from the water
• Gas-liquid contact inside the tower
• Treated water leaving the bottom
• Sour off-gas leaving the top
• How operating pressure can affect stripping performance

The Sour Water Stripper plays an important role in refinery and gas-processing facilities by treating contaminated water before it is sent for further treatment, reuse, or safe disposal.

🎥 This 3D animation is designed to provide a clear visual explanation of the equipment, internal flow, and stripping process.
