Formation of natural gas hydrate can cause blockages in subsea gas and oil flow lines, which can lead to catastrophic economic loss and ecological risks. In order to fully understand the plugging mechanism, a study on hydrate formation in pure water and inhibitor were carried out using a semi-batch stirred tank reactor at constant temperature and pressure. During the experiment, in-situ Raman analysis was used to monitor the time-dependent hydrate formation behavior such as capturing of guest molecules. Furthermore, in order to get vital information for capturing kinetics of guest molecules, in-situ Raman analysis and gas uptake measurement (kinetic experiment) ware carried out simultaneously. The present data and methodologies on the microscopic and macroscopic observations may contribute to better understanding of inhibition or hydrate formation mechanisms, and also practical applications for flow assurance in gas and oil pipelines. |
