Experimental Investigation of SO2 Removal from Flue Gases by Cleaning with Solution of Lime Suspension and Formic Acid

The experimental investigation presented in this research was performed order to examine the possibility of removal SO2 from flue gases by cleaning with a solution lime suspension and formic acid (Ca(OH)2 HCOOH). Research conducted laboratory plant (rotary kiln) 44 kW. mass (LS) 400 g. LS homogenized (mixed) sample cup 2 g (0.5%), 4 (1%) 8 (2%) 60% acid. placed gas washing bottle, where partial flow generated combustion diesel fuel injected. Simultaneously combustion, bottle injected rotary kiln. average concentration at entry point around 2900 ppm. results indicated that absorption 96.83%. Adding ratios 0.5% (2 g), 1% (4 g) 2% (8 resulted absorptions 99.25%, 98.77% 98%, respectively. LS, addition mentioned ratios, showed reduction sulfates pH value, rise sulfides calcium,
