Abstract

Gas hydrate formation involves low molecular gas mass transfer to a cage-like structure formed by water molecule under low temperature and high-pressure conditions. Gas hydrate is considered a problem if it develops along a pipeline. In order to solve the problem of gas hydrate formation in the pipeline, there is a need to understand the Interfacial Tension (IFT) behaviour at gas-water interface. This paper presents an experimental investigation of IFT of methane bubble in distilled water and varying concentration of salt (NaCl) using pendant drop (rising bubble) method. The results obtained shows that the IFT decreases with an increase in temperature and pressure. This decreasing trend shows that IFT existing at CH4 – H2O interface is a function of temperature and pressure. Additionally, the concentration of 2.9, 5.6, 8.2 and 10.7wt% NaCl resulted in an average increase of the IFT of the CH4-H2O system in 1.46, 2.57, 3.51 and 4.24 mN.m-1 respectively.
