Abstract

The performance of PVP and Luvicap EG, as commercial kinetic hydrate inhibitors (KHIs), in three different systems including methane, methane-terahydrofuran (THF) and ethylene were evaluated. A high-pressure rocking cell was applied to compare the effect of these two KHIs. The consumption of moles of gas versus time (hydrate growth rate) and the maximum subcooling in the presence of PVP and Luvicap EG were calculated. Results showed that the both polymers performed as inhibitors in methane and ethylene gas hydrate systems. However, in methane-THF system, the PVP was unable to reduce hydrate growth rate and the maximum subcooling temperature was lower than that of pure water, indicating poor inhibition performance of PVP in this system. The Luvicap EG polymer was superior to PVP in ethylene and methane-THF systems. However, in the methane gas hydrate system the PVP inhibition performance was better than Luvicap EG at a concentration of 0.1 wt%. While, at higher concentrations (0.3 and 0.5 wt%) the performance of Luvicap EG was excellent and completely prevented the formation of methane hydrate.
