Metal Structured Packing Packing Introduction
Yuanhai Metal Structured Packing is similar in construction to standard packing, except for a subtle modification in the geometry of the corrugation at the top and bottom of each packing layer. This relatively small change in geometry eliminates the abrupt change in flow direction of the liquid and vapor phases at the packing layer interface.
Conventional structured packing capacity is limited by flow interaction at the layer interface where the abrupt directional change limits the amount of counter-flowing liquid and vapor. As the liquid flow becomes restricted by the upward-flowing vapor, the liquid begins to build up at the layer interface which increases the pressure drop and may ultimately lead to flooding.
The geometry of Yuanhai structured packing relieves the liquid flow restriction. Because the premature build-up of liquid is eliminated, the low pressure drop characteristics of structured packing are better maintained throughout the efficient operating range of the packing. The benefits of Yuanhai structured packing are more significant for smaller corrugation crimp size, higher surface area packings. Depending on application and packing style, up to a 40% increase in capacity has been observed.

Metal Structured Packing Advantages
| Packed columns | Trayed columns |
| Lower pressure drop leads to significant power savings. (Greater than 5% reduction in power is possible.) | Higher pressure drop, but shorter columns. |
| High turndown capability. (Down to 40% of design capacity is possible.) | Limited turndown for efficient operation. (60-70% of design capacity is typical.) |
| Enables pure argon production by distillation, therefore eliminating need for a pure hydrogen source. | Can be used for high-pressure distillation. |
