A gas cyclone-liquid jet absorption separator integrates the functions of cyclone separation, liquid jet atomization, and absorption separation. This study employed this device to conduct a wet flue-gas desulfurization experiment on a gas mixture consisting of air in room temperature and sulfur dioxide (SO 2 ) to explore this device's prospect of tail gas purification. Sodium hydroxide (NaOH) and sodium carbonate (Na 2 CO 3 ) solutions at various concentrations were used as absorbents under room temperature. The changes in the SO 2 removal efficiency and air pressure drop were investigated with parameters including total gas flow, SO 2 concentration in the flue gas, and absorbent flow. The SO 2 removal efficiency increased to a certain extent as the absorbent concentration, total gas flow, and absorbent flow increased. The maximum SO 2 removal efficiencies of NaOH and Na 2 CO 3 were 85% and 77%, respectively. Under identical experimental conditions, the changes in SO 2 removal efficiencies of NaOH and Na 2 CO 3 exhibited essentially identical trends, in which NaOH exhibited a 5%-8% greater SO 2 removal efficiency than Na 2 CO 3 .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
