Alkali Based Wet Scrubber

Alkali Based Wet Scrubber

Alkali Based Wet Scrubber

(OP)
I am looking for the help with the best pH to operate a small NaOH based scrubber for controlling low concentrations (75 ppm ) of SO2 from a CHP exhaust, with a high CO2 content. I wish to minimise NaOH losses to carbonate formation while still removing SO2. Technical references as well as field experience most welcome.
Thanks in advance,
TISM
