Effect of Promoters on Associated Petroleum Gas Hydrate Formation Under Static Conditions

This study investigated the formation of associated petroleum gas (APG) hydrate from frozen solutions of promoterфs (sodium dodecyl sulfate and trisulfonated castor oil) under static conditions. The experiment utilized differential scanning calorimetry to analyze phase changes, such as ice crystallization, hydrate formation, and joint ice melting and hydrate formation. The visualization of the hydrate formation process helped identify factors that influence APG hydrates’ growth under the given conditions. The study concluded that the type and presence of promoters significantly affect the growth rate of hydrates, while the preparation protocol has a greater impact on the reproducibility of the process.
