Selection of Structured Packing over Trays

Selection of Structured Packing over Trays-

Selection of Structured packing over trays is also a factor of operational suitability.

  1. Packing can offer low pressure drop than trays.
  2. They provide more inter-facial area for better mass transfer efficiency.
  3. Height of the column can be shortened in case of packing compared to trays.
  4. They can handle corrosive fluids in better way than trays.
  5. It offers better separation efficiency.
  6. Better constant contact can be made in the operation.

Structured Packing over Random Packing-

Structured Packing can also be selected as per their performance in the operation. They are offering better workability over random packing like, it provides higher efficiency even with higher capacity and offers lower pressure drop. Liquid holdup is also reduced in the structured packing but they are costly than the random packing.


Advantages of Structured Packing-

Structured packing promotes filmed liquid distribution and which improves the overall performance. Textured designing of plates promotes liquid spreading. This packing is compatible with low pressure drop and high flow volume. Lower pressure drop means higher volatility which will be an advantages in operation. It reduces foaming even at higher operating rates.
