International audience ; Interest of Clathrate hydrates for industrial applications is rising. While numerous studies can be found on carbon capture or desalination, this effort investigates thermodynamics of the combined process using cyclopentane (CP) as second guest molecule. This document provides numerous equilibrium data of mixed CP/CO 2 hydrates in presence of salt (NaCl, KCl) under differents concentrations. Final dissociation points are collected, as well as intermediate dissociation points in presence of hydrates. While the first provide equilibrium data, the others are not at equilibrium. Indeed, Results show that, in presence of salts, several crystallization events occur in the system. Consequently, multiple hydrate structures could be formed in the bulk, such as pure CO 2 hydrates and mixed CO 2 /CP hydrates Finally, van der Waals and Platteeuw approach has been used and furnishes results within 0.4K uncertainty compared to this work and within 0.5K compared to literature. Besides, thermodynamic consistency of data has been evaluated.
