Let's see the process of water degassing: A good video to show all process.
Water Vacuum Degassing is an industrial process that removes dissolved gases (primarily oxygen, CO₂, nitrogen) from water by exposing it to a sub-atmospheric pressure environment. Unlike thermal degassing (boiling), it operates at lower temperatures, making it ideal for heat-sensitive applications.
⚙️ How It Works
Vacuum Chamber: Water enters a sealed tank where pressure is rapidly reduced (e.g., 1–25 inHg).
Gas Liberation: Under low pressure, dissolved gases exceed solubility limits → form bubbles.
Gas Evacuation: Bubbles rise and are extracted by a vacuum pump.
Purified Water Output: Degassed water exits, now chemically stable and non-corrosive.
(Physics Principle: Henry’s Law – gas solubility decreases as pressure drops)
