Real reservoir fluids contain a significant amount of intermediate/heavy compounds which are commonly regarded as non-hydrate formers. It is demonstrated in this study for the first time that cyclohexane, one of these ignored compounds, can form hydrates resulting in a significant reduction of the hydrate free zone for binary and ternary systems. Three sets of experimental data for methane-cyclohexane, nitrogen-cyclohexane, and methane-nitrogen-cyclohexane over a wide range of temperature have been reported. The set on methane-cyclohexane has been used in optimising the Kihara potential parameters for cyclohexane. The other two sets of experimental data were used in validation which proved the success of modelling.
