Abstract
The aim of this work is to present the experimental investigation of ethane hydrate formation kinetics in the presence of sodium halide salt solutions containing NaF, NaCl, NaBr, and NaI. To achieve this aim, the variations of pressure versus time have been measured during hydrate formation process. The temperature, volume of reactor and stirring velocity are 277Â K, 500Â ml, and 840Â rpm, respectively. The influence of anion type salts and their concentrations on induction time and hydrate formation rate have been studied. The result prove that sodium halides (NaF, NaCl, and NaI) at a concentration of about 0.6Â wt% and sodium bromide (NaBr) at concentration ranged 0.3-1.5Â wt% have minimum promotion effect on the ethane hydrate formation rate. Also, the results of present study show a significant decrease in hydrate formation rate at a concentration higher than 1.5Â wt% for sodium halides.
