The Ultimate Guide on How to Choose Random Packing

Do you want to buy random packing for your industrial application? Finepac Structures, the leading random packing manufacturer in India, brings you this guide to help you buy the right random packing for your needs.

With competitive price and timely delivery, HYF sincerely hope to be your supplier and partner.

Before you proceed to look at the factors to consider while buying the best random packing apt for your needs, let us look at a few general yet essential characteristics relating to the choice of random packing.

  • Your process requirements
  • Your familiarity and experience with a particular packing and application
  • If it is the direct replacement of an existing packing
  • If it can be used in the licensed process

Now, let us look at a few specific factors that will help you make a more precise and aligned choice.

1.Uniform Distribution

Random packings that you can fix together with other packing types can reduce the efficiency of the formation of channels. Additionally, packing must drain fluids freely to avoid liquid setting pockets, which was a common instance with their older saddle counterpart. 

2. The Surface Area of the Packing

A larger surface facilitates an increased vapor contact area and thus results in an increased surface area. So, the surface area of the packing constitutes a significant consideration while choosing the best random packing. 

3. The Uniformity of the Spreading Surface

A uniform surface area improves liquid-vapor contact, which, in turn, augments efficiency. When you compare the Raschig ring and pall ring, the latter has a better spread surface, and so, it provides higher efficiency levels.

4. The Material Used in the Random Packing

Random packings come in various types and hence involve the use of a range of materials. Each material type has its unique application, and therefore, you must make a choice accordingly. For instance, metal packings offer higher strength, capacity, efficiency and turndown, and higher compression resistance. On the other hand, ceramic packings suit high chemical inactivity. They provide low capacity and are breakable.

Now, plastic forms a popular packing choice. However, again, plastic cannot withstand temperatures above 120 degrees Celsius, based on the grade. Besides, since they degrade, you cannot use them in an oxidizing environment and solvent application. Their wettability is low, and which is why they aren&#;t as efficient.

5. The Rate Wetting

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.

6. 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.

7. The Void Created by the 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.
