In this study, vapor−liquid equilibria data have experimentally been measured for systems water + triethylene glycol (TEG) and water + TEG + toluene at 85 kPa and various temperatures. The VLE data were determined in a modified Othmer still, and the samples were analyzed using gas chromatography and titration methods. The NRTL, UNIQUAC, and Van Laar models were used to correlate the data. The results demonstrate the enhancement of volatility of water in water + TEG solutions and increasing the purity of the dehydrated TEG by the addition of toluene. Using this method, the more concentrated TEG can be obtained in the stripping columns of the natural gas dehydration systems.
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.
