Selection of absorbent tower packing for chlorine off-gas removal? PVC or PP?

The exhaust gas contains chlorine, which is absorbed using NaOH solution. The packing material used in the absorption tower was previously PVC-H; it corrodes and breaks down every year. We would like to change the material – is it possible to use PP packing material instead? ? The concentration of NaCLO in the tower’s internal circulation spray is around 5%, with the pH maintained between 8 and 9.

We use PVDF; it has been in use for 10 years.
