Hydrate formation can cause serious problems in hydrocarbon exploration, production, and transportation, especially in deepwater environments. Hydrate-related problems affect the integrity of the deepwater platforms, leads to equipment blockages, and also increases operational costs. In order to solve these problems, salts are used as thermodynamic inhibitors and also mixed with the drilling fluids in most drilling processes. A comprehensive understanding of hydrate formation in aqueous salt ...
The dissociation conditions of methane hydrate in high concentration aqueous solutions of NaCl, KCl, and CaCl2 are reported in this work. A total of 80 sets of H−L−V equilibrium data of methane hydrate in aqueous solutions of NaCl (9.45−23.71 wt %), KCl (13.93−21.88 wt %), and CaCl2 (13.78−35.50 wt %) were measured at the temperature range of (273.65−291.85) K and the pressure range of (5.43−65.12) MPa. A modified step-heating method with high efficiency was employed in the meas...
