Hi,
I am looking for an efficient way to re-use packings form a tower contining 98% H2SO4.
Removal of old packings is by vacuum, while replacing them must be carried out by hand. TO avoid handling acid comtaminated packings, we dispose of teh old packings and replace with new ones.
Does anyone have any experience of recovering packings in this way? The packings are ceramic and are assumed to have absorbed some acid.
The aim is to reduce waste, so we do not want to generate volumes of weak acid for washing, or risk adding neturalizing compounds back into the tower at teh end of the process.
Thanks
