Degasification involves the removal of dissolved gases from water or aqueous solutions. This process is most commonly used for removing oxygen, carbon dioxide, and nitrogen from water. It involves pumping water through a degasification tower, which is configured with trays or packing to maximize surface area exposure. The pressure of the water flow is reduced for better gas removal.
