Scrubber tower packing is an essential part of the system by providing an area for liquid and gas contact. Without proper or sufficient liquid gas contact a scrubber will not produce the designed results and could result it costly repairs and redesigns. Special consideration should be given to the selection of scrubber tower packing. Things to consider when evaluating and selecting scrubber tower packing include. Size, configuration, surface area, weight, void space and material of construction.
Scrubber Tower packing is manufactured in a variety of materials including thermoplastics, metals and ceramics. To determine the most suitable material of construction for your random packing the operating temperature and the composition of the gas and liquid must be considered. Applications that involve higher temperatures or highly corrosive elements may require high performance or exotic materials. For example, KemFlo manufactures plastic random packing in a variety of thermoplastic resins such as general purpose polypropylene, NSF polypropylene, polypropylene with glass, Polyvinylchloride, CPVC, PVDF, Tefzel and more in order to accommodate a wide variety of application. Make sure that the raw material used to manufacture the plastic random packing that you are utilizing is traceable back to the resin batch from which it was made. All of KemFlo’s plastic tower packing is traceable back to the resin manufacturer’s batch. In general metal packing may be made from a variety of materials including stainless steel, Inconel, Hastelloy and more.
The configuration or design of a specific tower packing varies greatly. Scrubber tower packing is designed to maximize efficiency and to be strong enough to withstand an acceptable amount of exposure to pressure, temperature, weight and flow. The purpose of scrubber packing is to provide surface area for liquid and gas contact but also provide enough open area as to not restrict flow. There are basic styles of scrubber tower packing to choose from and there are high performance tower packings. KemFlo manufactures several basic or traditional styles of plastic random packing including the Pall Ring and Saddle style. The Pall Ring is a barrel shaped or ring shaped packing that features an open wall construction which helps to maintain even liquid distribution. Kemflo manufactures the Pall Ring in three different sizes including 1”, 2” and 3.5”. Saddle style plastic random packing has serrated edges which promote high mass transfer rates. KemFlo manufactures the Saddle in 1”, 2” and 3” sizes. For those looking for more out of their scrubber tower packing KemFlo offers the Tri-Pack which is a high-performance plastic random packing. The Tri-Pack is a hollow spherical scrubber packing which is uniquely designed. The Tri-Pack offers a superior geometric shape which promotes high mass transfer rates. The spherical shape of the Tri-Pack also allows each part to roll into the packed position without creating any void spaces within the packed bed. The Tri-Pack offers an excellent surface area to void space ratio and is the most efficient plastic random packing on the market today. The Tri-Pack is available in 1”, 2” and 3.5” sizes.
