RE: CO2 vs H2SO4
In several of our plants we have changed to CO2 based nuetralization with very good results. Praxair was really pushing this technology at one time so maybe they can be a good contact for evaluating a CO2 based system.

Additionally CO2 is not corrosive as a gas, however, since CO2 is heavier than air asphyxiation is always a hazard.
You also should be aware that the dissolved CO2 increases the water alkalinity. If you have water with hardness in it, you can create a water that has the potential to scale.
