500X Metal Structured Packing Round Shape

500X Metal Structured Packing Round Shape 650 - 100mm Tower Packing Layer

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.

Applications of metal structured packing:

1. In ethylbenzene/styrene separation, after a sieve tray column was revamped with corrugated orifice packing. Under the same overhead operating pressure, the pressure of the reactor decreased from 32000 Pa (320 mbar) to 13500 Pa (135 mbar), and the pressure drop decreased from 24700 Pa (247 mbar) to 6200 Pa (62 mbar), the temperature of the reactor decreased from 104 to 83 degrees, and the reflux ratio decreased from 9 to 6.5. The treatment capacity increased from 16500 kg/h to 28300 kg/h (increased by 70%), the degree of polymerization decreased from 0.5% to 0.1%, and the steam required per ton of product decreased by 25%. The remarkable effect of increasing production and saving energy was achieved.
2. A 6500 t/a atmospheric distillation unit was revamped with orifice corrugated packing for propylene oxide separation.
3. Revamping of Lubricating Oil Vacuum Fractionation Tower, Replacing Tower Plate with Orifice Plate Corrugated Packing and Cascade Mini Ring.
4. Gas oil vacuum distillation column uses corrugated orifice plate structured packing instead of random packing.
5. Replacing original plate tray with corrugated packing of orifice plate in ethylene water quenching tower.
6. Ethylene/ethane high pressure distillation column was reformed with corrugated packing of orifice plate.
7. Cyclohexanone / Cyclohexanol Separation Column with Regular Packing with Corrugated Pore Plate
8. DMT Separation Tower, uses Corrugated Plate structured packing instead of Random Packing

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.
