Materials of Construction
The most common material used for Hualai structured column packing
is SS 304L and SS 316L. However Hualai manufactures this solely based on our customers’
requirements and can also be made from other materials based on
special requests.
Uniform Liquid Distribution
In order to achieve even liquid distribution over the packing it is
a must to have a good liquid distributor to maximize the
interaction of the liquid and vapor. However if the packing height
exceeds 3 meters we recommend using an intermediate liquid
re-distributor as well for even flow.
Fixing and Installation
It is a very basic and simple procedure. Once we have optimized the
dimensions of the packing we must ensure that the inside of the
column is clean and has no weld joints or bulges to obstruct the
installation. The supporting structure can be made of two cross
bars at 90 degrees to each other and in larger columns the same
construction must be repeated at a pitch of 150mm.
Once the support is in place, successive modules of Hualai
structured packing must be inserted from the top – down. Normally a
wooden disc (having a slightly small diameter than the packing) is
mounted on a pole and used to push each segment down to their
position due to the very narrow diameter of the column.
Surface Treatments of Sheet Metal Structured Packing
It is important to achieve good contact between the liquid and
vapor phases. A packing that spreads the liquid evenly in a thin
film will exhibit beter performance. Mixing the film creates
turbulence that enhances the mass transfer.
Modifications to the texturing of the packing surface improve the
liquid spreading which, in turn, leads to enhanced packing
efficiency.
All types of Hualai structured packings are available in a variety
of corrugation sizes. This provides the versatility needed to
optimize a packing configuration to best meet the efficiency,
capacity, and pressure drop requirements for a particular
application.
Compare: Packed columns offer multiple benefits
| 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.
