Absorption of SO2 and NO through an integrative process with a cost-effective aqueous oxidant

Publication date: Available online 5 July 2016 Source:Perspectives in Science Author(s): Chelluboyana Vaishnava Raghunath, Poornima Pandey, Roli Saini, Monoj Kumar Mondal Due to the substantial influence on the environment and health, there has been an intensifying environmental concern on sulfur dioxide (SO2) and nitrogen oxide (NO) discharge to the atmosphere all over the world. Flue gas of coal-fired power stations is major leading source for the emission of SO2 and NO. Cost-effective and balanced technologies for the reduction of these pollutants from flue gas have become increasingly essential at the present time. The preliminary experimental attributes were retrieved in a batch scale agitating bubbling reactor for instantaneous absorption of SO2 and NO using aqueous oxidant. The prime conditions for instantaneous absorption examined were including absorbent concentration, reaction temperature, and pH in the fabricated flue gas system. Removal efficiencies of 99% for SO2 and 85% for NO were acquired, respectively under absorbent concentration 5g/100ml, reaction temperature 313K, and pH 5.6.
