Limestone is used to neutralize the sulfur gas produced during the burning of heavy oil in the process of electric generation and desalination to produce synthetic gypsum. Characterization studies were carried out on flue gas desulfurization (FGD) gypsum produced by the Rabigh Arabian Water and Electric Company with the aim of finding out viable commercial applications.
On comparison of the chemical analyses carried out between the SGS laboratory and Anzaplan of Germany from the collected samples, it was found that the results are almost identical. CaO is 32.8 percent (SGS) and 32.9 percent (Anzaplan). SO3 is 45.89 percent (SGS) and 44.5 percent (Anzaplan). FGD gypsum compares well with natural gypsum. The bulk chemical data also show that there are no elements harmful to the environment.
