  • Water Boiling Temperature vs Pressure in Vacuum

    Water Boiling Temperature vs Pressure in Vacuum Table Chart. The boiling point of water is the temperature at which the vapor pressure of the liquid water equals the pressure surrounding the water and the water changes into a vapor. Water at high pressure has a higher boiling point than when that water is at atmospheric pressure.

    With vacuum degassing, water can also be degassed below 100°C by boiling. Creating a corresponding negative pressure (partial vacuum) in the degassing unit enables the boiling point to be reached as early as in the 30-80 °C range. This degassing process is suitable when no hot steam is available for operating thermal pressure degassing.
