Gas Hydrate Gas Hydrate Equilibrium Measurement and Observation of Gas Hydrate Dissociation with/without a KHI

Procedia Engineering, 2016
AbstractThis paper presents new gas hydrate equilibrium data's for C2H6 (structure I) and CH4 + C3H8 (structure II) with and without the presence of sodium chloride. Macroscopic observation of gas hydrate dissociation under the presence of kinetic hydrate inhibitor (KHI) is also presented and compared with cells that have no inhibitor.
