ABSTRACT
Specially designed equipment based on a static-analytic method with RolsiTM pneumatic samplers for on line gas chromatograph analysis has been used for this work. Operating pressures and temperatures are between 0.3 and 10MPa and between 293 and 393 K. Vapor pressures over liquid liquid mixtures and benzene solubility data are reported herein for benzene with amine aqueous solutions (methyldiethanolamine (MDEA) and diglycolamine (DGA)). Modelling of solubility data is achieved using a simple model based on activity coefficients.
