Formation of natural gas hydrate is a serious problem in the gas and oil industry because it can plug pipelines and destroy the equipment. This study aimes to evaluate the concentration effect of glycol ethers on their synergism with a commercial kinetic hydrate inhibitor (Luvicap ۵۵W) in sweet natural gas-water systems at a constant temperature of ۴ oC and pressure of ۹۵ bar. Hydrate formation experiments have been designed and conducted in a static, stirred autoclave. Finally, the results indicated that concentration changes dosen’t affect the inhibition time greatly, while the growth rate of hydrate crystals decreases considerably with the increase in the concentration of glycol ethers.
