Frequently Asked Questions (FAQ)
Q
What is metal mesh corrugated structured packing used for?
Metal mesh corrugated structured packing is widely used in distillation, absorption, and stripping columns across the chemical, petrochemical, and pharmaceutical industries. It is especially effective for separating corrosive mixtures, rectifying organic halides, and purifying air in chemical plants.
Q
What are the main advantages of mesh corrugated packing over random packing?
Compared to random packing, mesh corrugated structured packing offers a significantly larger specific surface area, resulting in higher separation efficiency. It also provides lower pressure drop, higher capacity, greater operational flexibility, and superior resistance to acid and alkali corrosion, including H₂S, naphthenic acid, and Cl⁻.
Q
Which model is suitable for high-capacity applications?
For high-capacity applications with larger corrugation pitch and wave height, models such as 100Y and 125Y are recommended. They feature higher void volumes (up to 87.5%) and higher F-factors, allowing greater gas throughput. For higher separation efficiency in tighter spaces, models like 350Y or 450Y are more appropriate.
Q
Can this packing be used under vacuum conditions?
Yes. Metal mesh corrugated structured packing is suitable for operation under vacuum conditions, including at absolute pressures as low as 100 Pa at the column bottom. Its low pressure drop characteristics make it particularly well-suited for vacuum distillation processes.
Q
Is this packing compatible with all tower diameters?
Yes. One of the key advantages of metal mesh corrugated structured packing is its compatibility with all tower diameters. It is suitable for both new tower designs — where it can help reduce the required tower diameter — and for retrofitting existing towers to significantly increase their throughput capacity.
Q
What materials are available for metal mesh corrugated structured packing?
Metal mesh corrugated structured packing is typically manufactured from stainless steel (304, 316L), carbon steel, titanium, and other alloys depending on the specific corrosion resistance requirements of the application. The choice of material is especially important when handling highly corrosive media such as H₂S, naphthenic acids, or chloride-containing streams.
