Selling Kempac Random Packing

When customer contact KemFlo regarding plastic random packing they typically have an idea of what they are looking for in general terms but rely on Kemflo’s sales team to walk them through the various options in selecting the best random packing for their specific application. Every customer’s needs are different. Some customers are looking to optimize the performance of their scrubber while other are more concerned with overall cost, but most customers are looking for a balance between performance and operating cost. Therefore, it is important to present customer with all available plastic random packing options.

Typically the discussion begins with what style of packing the customer is looking for. Do they want a high performance packing such as the Tripack or do they want a more basic packing such as the Pall Ring or plastic saddle style? KemFlo’s Tripack plastic random packing is a high performance plastic random packing which is uniquely designed with a network of rids, structs and drop rods which optimize efficiency by providing both significant surface area but at the same time also has plenty of open space. The Tripack also has a spherical design which prevents settling and nesting in a packed bed.

While KemFlo’s Pall Ring offers a more basic design than the Tripack it has many excellent features and performs excellent in most applications. The Pall Ring consists of an open wall construction which maintains even liquid distribution throughout the packed bed. The reinforced structs of the Pall Ring also provide additional surface area for gas and liquid contact and also provide substantial support to the outer ring.

There is also the plastic saddles style random packing to consider. The Saddle style does not give the performance of the Tripack but it does offer durability and a very ling track record. The Saddle style plastic random packing has been used for many years and in many applications.

Determining the packing size is also critical. The Tripack and Pall Ring are available in 1”, 2” and 3.5” while the plastic Saddle style packing is available in 1”, 2” and 3”. Determining the proper packing size is based on column size and other date such as flow rates and pressure.

Another very important aspect when it comes to purchasing plastic random packing is the selection of resin. KemFlo’s Tripack, Pall Ring and Plastic Saddle style packing are all available in a variety of resins. Some of the more common resins include Polypropylene, Polypropylene with glass fill, PVC, CPVC, Kynar, Tefzel, Teflon and Halar. KemFlo offers other resins upon request. All of the resins that KemFlo uses to make their plastic random packing comes from manufactures in either the United States of America or Canada. Most importantly all of the resin that KemFlo uses is traceable back to the manufacture’s specific batch.

Once a specific packing is selected KemFlo ensures that our customer’s order is manufactured under strict quality control procedures and shipped is a timely fashion. Expediting emergency orders is also available upon request.

Tri-Pack Makes the Difference

A major municipality in Southern Florida was experiencing significant problems with several odor control scrubbers. Heightened levels of Hydrogen Sulfide gas had resulted in major odor issues. In addition to the significant odor issues they were experiencing due to high levels of Hydrogen Sulfide there was also a problem with corrosion. The high levels of Hydrogen Sulfide gas was also greatly accelerating the rate of corrosion of the scrubber equipment. After a through inspection of the scrubber units the maintenance supervisor discovered that the plastic random packing had become brittle and was breaking into small pieces. The broken pieces of plastic random packing were collecting at the bottom of the scrubber restricting the liquid and gas flow. The flow restriction or plugging of the unit prevented the scrubbers from functioning properly resulting in increased odor and corrosion.

The facility maintenance supervisor wanted to find a plastic random packing that was more efficient and less prone to plugging so he reached out to KemFlo for assistance. We discussed the potential options which included the Tri-Pack, Pall Ring and saddle style plastic random packing. While all of Kemflo’s plastic random packing styles would have performed better than their existing random packing, he selected the Tri-Pack for a variety of reasons. The Tri-Pack’s efficiency, durability and resin quality were among the reasons it was selected to replace their under performing plastic random packing. The Tri-Pack has a spherical shape which makes it easy to install and prevents void areas within the packing bed unlike irregular shaped packing or random packing with excessive pins and appurtenances. Because of this there is no need to make allowances for nesting and settling. The Tri-Pack has a unique design made up of ribs, struts and drop rods which provide significant surface area for liquid and gas contact but still allows plenty of open area for liquid and gas flow. The Tri-Pack offers consistent loading which means reliable and predictable performance. It’s superior geometric shape and active surface area are vital to mass transfer. While some plastic random packing manufacturers claim to have more surface area, surface area alone is not an indication of performance. In fact excessive surface area can result in improper gas flow, improper liquid contact and always results in higher pressure drop which increases operating cost.

Another reason KemFlo’s Tri-Pack style plastic random packing was selected for this application was the high quality of the raw material used to make it. KemFlo uses only high grade plastic resins to manufacturer all styles of random packing including the Tri-Pack. For quality control all of the resin that KemFlo uses in their manufacturing process can be traced back to the resin manufactures specific resin batch. This ensures that KemFlo’s customers are receiving random packing made from high quality raw material.

Since installing KemFlo’s Tri-Pack style packing their scrubber has performed above expectations and they have had no further problems with odor or equipment corrosion. KemFlo manufacturers the Tri-Pack in 1”, 2” and 3.5” sizes and it is available is a variety of resins. In addition to the Tri-Pack, KemFlo also manufactures a Pall Ring and plastic Saddle style random packing.
