- High capacity and low-pressure drop.
- High coking and fouling resistance. Also, high corrosion and erosion resistance.
- Excellent mechanical strength
- Reduced installation and removal time.
It is an adaptation of the conventional structured packing which uses a smooth metal packing surface to eliminate areas on the packing where fouling can begin.
This kind of structured packings is developed for severe services susceptible to fouling, coking, erosion, and applications involving high solid content.
It can provide extended operation in fouling services. Both, corrugated sheet metal and stamped blades are considered grid packing types as they are highly durable with large open areas for highly fouling process streams.
Random packing uses a random distribution of small packing materials to assist in the separation process, while structured packing uses larger, fixed packing structures.
