Dear friends,

I would like to know some benefits and cons of these two emission monitoring system. Are In-situ analysers reliable? In my case, when the furnace oxidation occurs, the SO2 levels increase and we need a fast response to increase the injection of lime. Which analyser is preferred in this case? What about using two analysers, one before and one after the desulfurization system?

Thx.
