The use of PVC/ Polypropylene pall rings inside the degasser column is to break up the water flowing down, which creates a greater surface area. This increased surface area allows for more efficient gas-liquid contact, facilitating the removal of dissolved gases from the water. By breaking up the water flow, the pall rings enhance the degassing process and improve the overall efficiency of the degasser column.

Nominal Filters -
- A) Does not have an absolute rating
- B) Are subject to media migration
- C) Cannot be tested to confirm integrity
- D) All of the above
Correct Answer

A. D) All of the above

Explanation

The correct answer is d) All of the above. Nominal filters do not have an absolute rating, meaning their efficiency can vary. They are also subject to media migration, where the filter media can move or dislodge during use. Additionally, nominal filters cannot be tested to confirm their integrity, making it difficult to assess their effectiveness. Therefore, all of the given statements are true for nominal filters.
