SO2 Wet Scrubber
Hello, I am designing a small scale Na2CO3 Wet Scrubber for removing SO2 from the atmosphere. Basically it’s a low vacuum drum whereby air is drawn
in the through the bottom and bubbles up the through the Sodium Carbonate solution.
This is what I reckon will happen :-) Please correct if wrong.
2 SO2 + 2 H2O = 2 SO2H2O
2 SO2.H2O + Na2CO3 = 2 NaHSO3 + CO2 + H2O
What I don't know is the optimum ratio of Na2CO3 to H2O and the resulting yeilds. IE 10G Na2CO3 dissolved in 1000ML H2O (10 deg C). Yeilding xG of
NaHSO3.

SO<sub>2</sub> reacts with water, forming sulphurous acid H<sub>2</sub>SO<sub>3</sub>.
The SO<sub>2</sub> content in air is measured in PPB (parts per billion) so a very small yield is to be expected . . .
