Laboratory tests have been performed using a stirred cell where SI and SII gas hydrates have been formed
under the presence of the kinetic inhibitor Poly Vinyl Caprolactam (PVCap) and INHIBEX. The latter is a
mixture containing 50wt% PVCap 2k and 50wt% butyl glycol. The effect of PVCap is enhanced by the
presence of butyl glycol; the latter acts as a synergist for the former. Dissociation temperatures were
obtained and compared for hydrates formed 1) in presence of PVCap and 2) in presence of INHIBEX. The
effect of INHIBEX concentration on the temperature of dissociation was also investigated. Systems
containing INHIBEX dissociated at lower temperatures than the corresponding systems with only PVCap
present. Furthermore, 3000 ppm INHIBEX mixtures were found to have higher dissociation temperatures
than 1500 ppm INHIBEX mixtures.
