Conversion of a desulfurization plant from quicklime to chalk requires high reactivity of the chalk products. In contrast to other CaCO 3 products, chalk, as a result of its origin, with a mean particle size of 2 to 3 μm is a sorbent offering high reactivity and the possibility for replacing the conventional lime additive. Further advantages of chalk over high‐calcium lime are economic efficiency and easy handling.
