The metal ring rectangular saddle packing is developed by Norton company in the United States. Its shape is between ring and saddle, so it has both advantages. On the basis of saddle shape, the metal rectangular saddle ring packing adds ring rib, avoids overlapping, ensures certain strength and rigidity, punches out several small claws, increases gas-liquid agitation, strengthens mass transfer, and produces unique performance.

      The metal saddle shape is called as the interlax packing for short in China and enjoys a high reputation in the world. This new type of high efficiency packing is used to equip new packing tower. Its height is 35% lower than that of plate tower, its diameter is 30% smaller, or its efficiency is increased by 10-30%, and its pressure loss is reduced by 20-60%. The experimental study of dry distillation instead of wet distillation in China shows that the investment can be reduced by 20%. In a word, the adoption of new type of ring moment saddle can increase the yield, low energy consumption or cost, and improve the separation efficiency.

     

     The metal saddle ring is a kind of packing, which can be widely used in distillation, absorption and other reactions.

     ● the metal rectangular saddle ring can be used in both vacuum tower and high-pressure tower.

     The metal moment saddle ring can be applied to mass transfer towers with different diameters. It is often used in vacuum tower, in which low pressure drop is important. At the same time, it is often used in high-pressure tower, its capacity is much larger than the typical tray.
