does any one has experience about gas treating due to below description:

i see the gas sweetening package PID ,in this method we have absorption column and solution oxidizer ,

as i know in this process from the oxidizer column FE+++ send to absorption column  to contact with sour gas and after that FE++ go back the oxidizer for regeneration

we have some chemical that add  to the oxidizer like CHELATE,BIOCIDE,SURFACTANT,KOH and k2s2o2

and also with blower air send to oxidizer

i want to know in this process how the gas treat and h2s absorbed 

what is the role of mentioned chemical why we use in oxidizer

in this process we have sludge, sulfur separate in absorption column or oxidizer column?

 oxidizer vessel is conical
