The shape of metal packed saddle ring is between ring and saddle, so it has the advantages of both. The structure of the metal saddle ring filler in the saddle shape on the basis of the increase of ring reinforcement, to avoid overlapping, ensure a certain strength and rigidity, out of a few small claw, increase the gas-liquid agitation, strengthen the mass transfer, so as to produce a unique performance.

The metal moment saddle ring is also referred to as interlock packing in China. This new type of packing is used to equip a new packed tower. Its height is 35% higher than plate tower, its diameter is 30% lower, and its pressure loss is 20-60% lower. Domestic dry distillation instead of wet distillation experimental study shows that the investment can be reduced by 20%. In conclusion, the new ring torque saddle can increase the yield, reduce energy consumption or cost, and improve the separation efficiency.
