Lime and limestone are used in the treatment of pollutants such as sulfur dioxide (SO 2), hydrogen chloride (HCl), hydrogen fluoride (HF), sulfur xide (SO 3), arsenic (As), selenium (Se), fine particulates and mercury (Hg).. Lime and limestone products are used in both wet and dry flue-gas desulfurization (FGD) processes.

value is determined as 12 for hydrated lime slurry (Ahlbeck et al., 1993). It is well known that the increasing the alkalinity will increase dissolution rate of SO2 and the rate of sulfation reaction, thus the total sulfation capacity increases. The main drawback for using hydrated lime as a sorbent in wet FGD system is the cost of lime which ...

ABSTRACT. Wet flue gas desulfurization (WFGD), using limestone with forced oxidation (LSFO), is a common Flue gas desulfurization (FGD) process where limestone reacts with SO 2 to produce gypsum (CaSO 4.2H 2 O). In South Africa, Eskom's Kusile Power Station utilizes conventional wet ball milling to grind high-grade limestone …

The most commonly used slakers are ball mill slakers and paste slakers. Though ball mill slakers produce finer particles, which have more surface area, paste slakers produce a less abrasive slurry and have lower capital costs and lower power requirements [5]. The solubility of lime is another factor that is believed related to lime reactivity.
