Experimental study on the equilibrium ethane hydrate formation conditions in aqueous electrolyte solutions

An experimental apparatus for the determination of the vapor-liquid-hydrate incipient equilibrium conditions was built. The apparatus was used to obtain equilibrium hydrate formation data for ethane in aqueous solutions of NaCl, KCl, CaCl 2 and KBr in the temperature and pressure ranges of 265.36-282.98 K and 0.488-2.188 MPa. The experimental data were compared with the predictions by using the method of Englezos and Bishnoi (1988)
