Everything about Plastic Random packing for corrosive applications

Earlier known as dumped packing and used popularly in the gas, chemical plants, and refinery random packing is traditionally used for the fractional operations. It has been used to increase the tower’s capacity, and therefore it is a cost-effective and efficient solution used from several decades. Its effectiveness is looked in the dehumidification of air where LiCl (lithium chloride) is utilized.

With the innovations and new outcomes, random packing displays improved products for the new generations. Available in three different varieties (materials) plastic, ceramic, and metals based on different operational temperatures, the optimum utilization is made for the mass and heat transfer.

 

In addition to better performance benefit, there are many other advantages of random packing.

 

Below-mentioned is a few more benefits:   

 

- The pressure drop reduction throughout the column

- Liquid holdup reduction in the column

- Capacity increment at the same efficiency in comparison to the trays

- Available in different geometrics and materials

- Used widely for absorption, fractionation, and stripping operations

- It can easily be replaced and stored in heavy fouling

 

Different types of Random Plastic packing materials available: 

Plastic C-ring:

It is similar or says equivalent to the CMR (Cascade Mini Ring). In comparison to pall ring, it has better efficiency and capacity with low ration aspect (1:3). It is highly fouling resistance and has a high capacity rating.

 

Plastic P-ring:

It is equivalent to pall ring used commonly in industries and available in PE, PVDF, PP, PVC, PFA. It has versatile and standard packing. The plastic pall ring is an advanced version of raschig ring and offers an effective surface area in comparison to others.

 

Plastic star packing:

 It has excellent characteristic of capacity and versatile packing for demanding application which is equivalent to intalox snowflake.

 

As there are different random packing options available, it is important to look around that which is the best one that offers maximum performance.

 

For the industrial applications, available in different sizes, the capacity and efficiency required is the specified thing which needs to be considered. To meet the corrosion and temperature requirement in lowest material the random packing is chosen over the structured packing. 

 

Different places where random packing is used: 

 

- The small diameter of the tower (less than 3 ft.) 

- Low-pressure drop process 

- When operation tower has low capacity

 

While looking for the random plastic packing consider t mentioned below things for cost-effective solutions:

 

- Look at the process requirement, whether it meets your criteria or not.

- Whether it’s a direct replacement of the existing packing

- Check the certain packing with a specific application

 

Final verdict:

 

Finepac Structures offers a complete structured tower packing option with different types, patterns and maintains for the clean service. It is a leading manufacturer who offers a complete solution for the corrosive applications through Random packing. The products are well suitable, cost-effective and structured filters which can attack a wide range of custom solutions. The best random plastic packing must be affordable as per the budget and corrosion resistance in nature.
