The Kinetics Of Gas Hydrate Formation Using Sodium Dodecyl Sulphate As The Promoter

This final year project will be studying on the kinetic formation of gas hydrates using sodium dodecyl sulphate as the promoter. This report encompasses of background study, problem statement, objectives and scope of study, literature review on gas hydrates and SDS, proposed methodology for carrying out the experiment, project timeline management and lastly conclusion. Our main problem statement is the increasing greenhouse gas emission and the energy intensive carbon dioxide capture calls for a cheaper and more effective alternative. Furthermore, depleting fossil fuels also seeks for alternative energy source. Gas hydrate is seen to have a high potential for carbon dioxide capture and as well as an energy source but unfortunately the current rate of hydrate formation is not in favour of time. Hence, this project studies gas hydrate formation kinetics to increase its formation rate by using promoters. This project is mainly about identifying the optimum concentration of Sodium Dodecyl Sulphate as the promoter for gas hydrate formation. The gas involved in this experimental work is carbon dioxide and methane. This is identified by calculating the induction time of gas hydrate formation and apparent rate of formation of gas hydrate at different SDS concentrations. At the end of the experiment, the data collected will enable us to understand better on how carbon dioxide and methane hydrate can be produced and are believed to be used for in-situ carbon dioxide sequestration through methane hydrate dissociation. Through two semesters of experimental work, which the first half denotes a deeper understanding of the theories of kinetics of gas hydrate whilst the second half will encompass the experimental work to address the problem statements identified.
