Grid structured packing combines high surface area of traditional structured packing and rugged construction of the common grid configuration. It can provide high heat transfer efficiency, high mechanical strength and antifouling characteristics in severe services that are prone to plugging, coking, erosion and containing solids. The smooth surface provides low liquid hold up, reduces the residence time and the possibility of coke formation.
There are two pieces mellagrid structured packing fixed by screw.
Specification
Material: SS304, SS304L, SS316, SS316L, SS904L, SS410S, Alloy C276, Alloy 400, etc.
Feature
Suitable for coking and fouling applications due to its geometrical structure and smooth surface.
The structure and element height allow for easy cleaning.
It can be removed, unscrewed and cleaned with a water jet.
Efficient dissipation of temperature.
Mechanically robust structure.
Much better separation efficiency than traditional grid structured packing.
Typical application (oil refineries).
Application
Grid structured packing is used for fouling, erosion, coking and high solids content applications. Such as: crude tower pump-around, vacuum tower pump-around, cracked gas quench towers, FCC main fractionator slurry pump-around, quench towers in steel mill, coker fractionator wash section, atmospheric crude unit wash section, crude vacuum unit wash section, flue gas absorbers/scrubbers. |
