INFLUENCE OF MELTING RATE ON THE DISSOCIATION OF GAS HYDRATES WITH THE KINETIC INHIBITOR PVCAP PRESENT Gulbrandsen, Ann Cecilie; Svartaas, Thor Martin

Abstract

The kinetic inhibitor Poly Vinyl Caprolactam (PVCap) was added as a kinetic inhibitor to the gas-water system. Different hydrate formers were used in order to obtain formation of the different hydrate structures (sI, sII and sH). All hydrate structures were formed with PVCap. The effect of applying different melting rates was investigated. The isochoric technique was used to obtain dissociation temperatures and corresponding pressures. The melting rate was found to be a parameter influencial for the dissociation temperature. Even for very slow melting rates such as 0.0125 Kelvin per hour, the final dissociation temperature was significantly higher that the dissociation temperature for the corresponding non-inhibited system.
