Apr 14, 2022Limestone is very inexpensive, but control efficiencies for limestone systems are limited to approximately 90%. Lime is easier to manage on-site and has control efficiencies up to 95% but is significantly more costly. Proprietary sorbents with reactivity-enhancing additives provide control efficiencies greater than 95% but are very costly.

Particles that are either coarse or too large often tend to not stick together, or may stick together, but have a lot of void space, creating a weak pellet with a low density. Limestone or gypsum, which are more finely ground, help to fill in the void spaces between coarse particles, promoting a more dense pellet with fewer void spaces.
