It has been accepted that separation of low boiling-point gas mixture via hydrate technology has the advantage of operating at around 0℃

and therefore can reduce the refrigerating energy consumption dramatically. It is necessary to study the simulation algorithm for the operation process because this separation technique is still at the stage of theoretical research and has not fulfilled practical industrial application. In this work

a process of hydration and absorption two-tower series operation was simulated by using the non-equilibrium stage approach

which involved hydrate formation kinetic model

hydrate dissociation kinetic model

and mass transfer kinetic model when gas was absorbed in water-in-oil emulsion. The effect of operation parameters of two series towers

such as temperature

pressure on separation efficiency was investigated. The calculation results are of significance for designing separation process for low boiling-point gas mixture via hydrate technology

and can also lay a theoretical foundation for industrial application of this separation technique.
