Abstract: | Kinetic experiments were performed on a methane-water system in the presence of Type-I Antifreeze Proteins (AFPs) in order to elucidate their effectiveness as kinetic hydrate inhibitors, specifically their effect on the hydrate growth period. The results were compared to experiments done with a classical polymeric kinetic hydrate inhibitor, N-vinylpryrrolidone-co-N-vinylcaprolactam poly(VP/VC)] at the same pressure, temperature and weight percent conditions. As well, a series of experiments was conducted on poly(VP/VC) to examine the effect of concentration on hydrate growth inhibition. Experiments were performed at temperatures between 275.15 and 279.15 K and pressures between 5800 and 7200 kPa. The effect of the polymer on the hydrate growth profile was examined as well as the effect of temperature and pressure on the performance of the polymer and the protein. |
