Low-Cost De-sulphurization of Flue Gas

Abstract

This patent application introduces an inventive Flue Gas De-sulphuration (FGD) process for exhaust gas emissions. The process incorporates chemical solution mixes directed through exhaust chimneys via a natural draft mechanism, undergoing sequential treatments with calcium oxide (CaO) and sodium hydroxide (NaOH). The method not only achieves effective de-sulphuration but also integrates pH adjustment and fertilizer production for a comprehensive and sustainable solution. The low-cost Flue Gas De-sulphuration (FGD) process for exhaust gas emissions offers several advantages over conventional methods. This innovative approach involves directing chemical solution mixes through exhaust chimneys via a natural draft mechanism, undergoing sequential treatments with calcium oxide (CaO) and sodium hydroxide (NaOH).
