If random packing is required for your application, Kem Group USA can help you determine the most efficient and economical plastic random packing. As a leading manufacturer of plastic random packing Kem Group USA offers random packing in a variety of sizes, configurations and materials. Kem Group offers the Tri-Pack, Pall Ring, Saddles and KemFlake random packing in a multiple sizes and resins.
The following should be considered what selecting the plastic random packing best suited for your application:
Uniform Distribution
Random Packing should facilitate even distribution of liquid and or gases through out the packed bed and be free of void spaces and channels. Some random packing products such as the Tri-Pack are specifically designed to avoid settling and nesting so that uniformed distribution through a packed bed can be achieved.
The Surface Area of the Random Packing
Too much surface area can impede proper gas and liquid contact and results in higher pressure drop resulting in increases in operating cost. Products such as the Tri-Pack offer the ideal surface area to open area ratio which results in excellent mass transfer efficiency.
Material Selection
Kem Group USA Plastic random Packing is available in a variety of resins such as polypropylene, glass-filled polypropylene, polyethylene, PVC, CPVC, PVFF, Trfzel, Teflon, Halar and more. The material selection of a plastic random packing is determined by a handful of factors including temperature, chemical composition and cost. The initial cost of a high performance resin may be significantly more than a general purpose polypropylene but will be more temperature resistant and will have longer product life.
The Packing Wetting Rate
The lower the wetting rate, the lesser the stability level of the packing. Dewetting happens when the falling liquid interrupts the liquid on the surface. As a result, when the packing surface dewets, the efficiency is reduced.
The Strength of the Random Packing and Minimized Friction
Mechanical damages form an essential part of the industrial part. Accordingly, the random packing you choose must provide resistance to mechanical damages caused on account of weight. Besides, minimized friction, with the help of an open shape with aerodynamic features, increases capacity. So, ensure that you check the friction levels before choosing a random packing.
Void created by random packing
Higher the void of the random packing, lower the resistance to vapor up flow, lower the pressure drop, and the higher the capacity. A higher capacity is the result of the particle size of the packing. The packing’s suitable size must strike a balance between capacity and packing efficiency.
Selecting the most efficient plastic random packing based on your specific application and process data can be a significant savings in both money and time. Strong consideration should be given to the above points as you evaluate different plastic random packing products. Kem Group gives you multiple options such as the Tri-Pack, Pall Ring and Saddle all available in three different sizes and multiple resins.
