Title: | Citrate process for SO2 recovery: Vapour-liquid data and correlation | Authors: | Škrbić, Biljana Cvejanov, Jelena Paunović, Ratomir |
Keywords: | SO2;Sodium;Citrate solution;Vapour-liquid data | Issue Date: | 1-Jan-1993 | Publisher: | Elsevier | Journal: | Gas Separation and Purification | Abstract: | Precise knowledge of the quantitative data of equilibrium vapour pressure of SO2 over aqueous sodium citrate solution is of considerable technological importance for the design of both absorber and regenerator. The absence of such data prompted a series of measurements to determine them. The ranges of experimental conditions used for measurements of vapour-liquid equilibrium data were: gas flow rate, 1.60-1.701 min-1; SO2 concentration in inlet gases, 0.50-6.00 vol%; temperature, 40-70°C at atmospheric pressure and citrate buffer with the molar ratio CNaOH/CH3Ci of 0.50/1 .00, 1 .00/1 .00 and 2.00/1.00. The equilibrium vapour-liquid data were correlated by the extended two-parameter model. Good agreement between experimental results and those predicted by the suggested model was obtained for the whole investigated region of interest for SO2 absorption. © 1993. | URI: | https://open.uns.ac.rs/handle/123456789/9867 | ISSN: | 09504214 | DOI: | 10.1016/0950-4214(93)85016-O |
