A lumen laminar flow and radial diffusion model was applied to calculate the membrane wall transfer coefficient from the data stripping a single volatile component, NH<jats:sub>3<\/jats:sub> or CO<jats:sub>2<\/jats:sub>, from their individual aqueous solutions. Influence of the type of membranes and operating conditions on mass\u2010transfer rate were discussed, especially the influence of the membrane transfer coefficient on the film mass\u2010transfer coefficient in the lumen. Appropriate configurations of the hollow\u2010fiber modules for stripping of a single component were analyzed to optimize mass transfer. To predict the stripping of NH<jats:sub>3<\/jats:sub> from a solution containing NH<jats:sub>3<\/jats:sub> and CO<jats:sub>2<\/jats:sub>, a mathematical model incorporating local chemical equilibria and Nernst\u2013Planck diffusion was developed to describe the mass transport. The models described the experimental data fairly well. The experimental results showed that the supported gas membrane process can be used to remove NH<jats:sub>3<\/jats:sub> effectively from aqueous media containing NH<jats:sub>3<\/jats:sub> and CO<jats:sub>2<\/jats:sub>.<\/jats:p>","DOI":"10.1002\/aic.690420715","type":"journal-article","created":{"date-parts":[[2004,6,23]],"date-time":"2004-06-23T10:35:18Z","timestamp":1087986918000},"page":"1945-1956","source":"Crossref","is-referenced-by-count":22,"title":["Hollow\u2010fiber gas\u2010membrane process for removal of NH<sub>3<\/sub> from solution of NH<sub>3<\/sub> and CO<sub>2<\/sub>"],"prefix":"10.1002","volume":"42","author":[{"given":"Yingjie","family":"Qin","sequence":"first","affiliation":[]},{"given":"Joaquim M.
