Sodium Bisulfite Production
Sodium Bisulfite Production
(OP)
I am searching for information on sodium bisulfite production. We are looking to absorb SO2 into a Caustic Soda solution. SO2 being generated via a sulfur burner with an SO2 concentration of ~18%. I am assuming that this can be done in a packed tower. Any info will be helpful. Thanks.

In this system, you should look at controls and interlocks to minimze any sulfur carry over. This can occur if insufficient combustion air is added to the combustion chamber. A UV detector is typically used in the hot gas stream to detect any burning sulphur particles and a turbity sensor can be used on the effluent from the primary quench tower as it will become milky with sulphur carry-over.
