Traditional systems for olefin/paraffin separation, like low-temperature distillation, are expensive and very energy consuming, and therefore, alternative separation methods are desired. Facilitated transport membranes are new tools for this separation to be substituted in large scale separation of olefin-paraffin mixtures. To design a membrane process for olefin-paraffin separation, equilibrium data is required. In the present work, silver nitrate (AgNO3) was used as the carrier for facilitated transport of propylene. The equilibrium constant value of the reaction between propylene and silver ions was determined by the volumetric method. The influence of pressure, temperature and silver ion concentration on equilibrium constant value was evaluated.
