Abstract: 

IS DEVELOPED TO CALCULATE THE PHASE EQUILIBRIUM OF PURE GAS HYDRATES (CH4, C2H6, C3H8, CO2, N2,). THE EQUALITY OF FUGACITY APPROACH IS USED TO MODEL THE VAPOR-LIQUID-HYDRATE PHASE EQUILIBRIUM. THE VAN DER WAALS AND PLATTEUW MODEL IS APPLIED TO DESCRIBE THE HYDRATE PHASE, AND PRSV2 EOS WITH VAN LAAR-TYPE TWO-BINARY-PARAMETER MIXING RULE IS CHOSEN TO CALCULATE THE FUGACITIES OF VAPOR AND LIQUID PHASES. THE MODEL PARAMETERS ARE FITTED TO EXPERIMENTAL DATA FOR PURE GAS HYDRATE, AND THIS MODEL IS ABLE TO PRECISELY PREDICT VAPOR-LIQUID-HYDRATE FORMING PRESSURE FOR SINGLE GUEST HYDRATE.
