Why Raschig Rings used as Degasser Tower Media?
Raschig rings are a type of random packing material used in various applications, including degasser towers. Degasser towers are typically used to remove dissolved gases, such as oxygen and carbon dioxide, from a liquid stream, usually water. The Raschig rings provide a large surface area for efficient mass transfer between the liquid and gas phases, promoting the removal of gases from the liquid. When Raschig rings are used in a degasser tower, they are packed in the tower column. The rings are typically made of ceramic, metal, or plastic materials and have a cylindrical shape with a diameter equal to their height. The packing arrangement creates a tortuous path for the liquid and gas to flow through, maximizing the contact between the two phases. As the liquid flows downward through the tower, the dissolved gases come into contact with the large surface area provided by the Raschig rings. This contact facilitates the transfer of the gases from the liquid phase to the gas phase. The
