Abstract
Besides other application of clathrate hydrates, hydrate-based CO2capture and storage are potentially important where additives are commonly used to speed up the hydrate formation processes in order to gain on scientific, technological and economic interest. In this work combination of additives such as tetrahydrofuran and sodium dodecyl sulphate (THF/SDS) on mixed gas hydrate formation and dissociation condition have been investigated using a graphical method. The measurements were carried out at temperature and pressure range of (265 to 300) K and (1 to 5) MPa. The presence of additive 3 mol % THF has drastically increased in the hydrate stability region while with the combination of SDS + THF lower the hydrate equilibrium temperature marginally.
