  • Deaerator - Refining, Hydrocarbons, Oil, and Gas

    -A deaerator expels dissolved oxygen from boiler feed water, taking advantage of decreasing O2 solubility in it as temperature becomes higher. Usual operating pressure of deaerator is in the range 0.1 - 1.0 Barg (operating temperature 102-120 oC), heating is implemented by bare steam. Practically all injected steam is used for heating, a

  • What is the main function of Deaerator tank? -

    A deaerator is a device that is widely used for the removal of oxygen and other dissolved gases from the feedwater to steam-generating boiler. In particular, dissolved oxygen in boiler feedwaters will cause serious corrosion damage in steam systems by attaching to the walls of metal piping and other metallic equipment and forming oxides (rust).
