pH measurement in the flue-gas desulfurization (FGD) process

Our need for energy is growing, and so is pollution. Burning fossil fuels like coal and oil releases a big amount of sulfur dioxide; an extremely harmful poison for man and environment. 

Flue-gas desulfurization process uses a simple chemical reaction: by adding calcium carbonate and fresh air, the sulfur dioxide turns into calcium sulfate, better known as plaster.

An optimal reaction is important for several reasons:

– it has to absorb as much sulfur as possible and cause as little pollution as possible

– a good quality of the plaster is necessary to achieve a good selling price.

The best indicator for monitoring the chemical reaction of the gas is the pH-value.
