Comparison of synergistic effect of commercial kinetic inhibitors with glycol ethers for natural gas hydrate formation

Natural gas hydrate formation is a serious problem in the gas and oil industry because it can plugpipelines and destroy the equipment. Inclusion of glycol ethers into a kinetic inhibitor solution wasfound to enhance the inhibitor performance during natural gas hydrate formation. In the present study,the effect of glycol ethers on the performance of 55W and EG commercial kinetic inhibitors at 4ºC andinitial pressure of 95 bar has been compared. The results indicate that the presence of glycol ethers has astronger synergistic effect with inhibitor 55W than with inhibitor EG.
