Description :
In two stages causticizing, effect of lime purity and lime dosage plays an important role. At higher purity levels of lime, we are getting better silica removal efficiency during two stage causticizing process at same temperature and retention time. At higher dosage of lime in first stage during two stage causticizing process, silica removal efficiency is improved, however, we need to balance the dosage of lime at first stage depending on the inlet silica level and mud silica to feed in to lime kiln.
