SS316L Structured Packing Corrugated Metal Sheet Corrugation Surface Treatment

SS316L Structured Packing Corrugated Metal Sheet Corrugation Surface Treatment

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.

Hualai structured packing uses the industry standard corrugated perforated and embossed sheet metal design to provide efficient vapour-liquid contact. The style of the embossed surface has been optimised to provide maximum wetability and numerous perforations enhance cross mixing of the process fluids. Type Y has a crimp angle of 45° and type X 30°. Suitable liquid irrigation range from below 0.5 up to 200 m3/m2.hr.

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.
