Abstract
In this research, investigation of ethylene hydrate formation kinetics was carried out in the presence of nanosilver suspension. The hydrate formation induction time was measured at 4˚C and initial pressures of 14 and 16 bar. According to the results, ethylene hydrate formation induction time decreased at all concentrations of nanosilver suspension in comparison to pure water. Also, the minimum induction time at the pressure of 14 bar was 21 minutes and at the pressure of 16 bar was 17 minutes which compared to pure water, 93% and 87% decrease was observed, respectively. Hydrate formation tests were also performed at 1.5˚C and 30 bar. Based on the results, in the presence of this suspension, hydrate storage capacity increased compared to pure water. The maximum storage capacity of 151.85 was achieved for 5 ppm of nanosilver suspension suggesting 261.3% increase compared to pure water.
