Equilibrium hydrate formation conditions for methylcyclohexane with methane and a ternary gas mixture

Equilibrium hydrate formation conditions for methane with methylcyclohexane (MCH), and a ternary gas mixture of methane, ethane, propane with methylcyclohexane are obtained by employing the isothermal pressure search method. Methylcyclohexane is reported to form structure H gas hydrates with a help gas. The equilibrium pressures of the ternary gas mixture–methycyclohexane system are higher than those of the ternary gas mixture without methylcyclohexane system at the experimental temperature range. The experiments are carried out in the pressure range of 0.935–11.933 MPa and the temperature range of 273.59–290.62 K.
