Abstract:
This paper details the design of a spray tower for wet flue gas desulfurization (FGD), a system aimed at removing sulfur dioxide (SO?) from flue gas. The design of the scrubber system's essential parts, such as the scrubber thickness, pipe network diameter, energy gain rate, and SO? removal efficiency, is the main emphasis of the study. A number of variables, including sorbent particle size and slurry concentration, affect how well SO? is removed. The study also shows that the scrubber system is less expensive initially than traditional alternatives and is easy to build. Furthermore, the process produces useful byproducts, especially gypsum, which may be utilized to make wallboard. The creation of these marketable byproducts lessens the difficulties associated with post-operation trash management. It has been demonstrated that magnesium hydroxide (Mg(OH)?) can successfully reduce visual opacity and manage sulfuric acid mist emissions. One of the system's distinguishing features, the procedure produces a high SO? removal effectiveness of 99%. Additionally, it achieves a 99.9% reagent usage rate and yields 99% pure gypsum. The suggested method is a great choice for treating flue gas in coal-fired power plants because of these benefits.
