The principle of Vacuum Deaerator is based on the Henry's Law that is at a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid. The partial pressure of steam add, at the same time the partial pressure in the water reduce when the water is boiling. Water is full of steam and no longer has the dissolved gases dissolved gasses precipitates from the water. We can know it from the saturation of the water, the low temperature water can boiler in the vacuum. The Ordinary Temperature Vacuum deaerator is designed by using this characteristic to remove the gas( including oxygen). The Ordinary Temperature Vacuum deaerator is apply remove oxygen from injection water and removed carbon dioxide after water treatment.
