Phase equilibria of CO2+N2 and CO2+CH4 clathrate hydrates: Experimental measurements and thermodynamic modelling

▸ A thermodynamic model based on the CPA EoS and vdW-P theory is applied. ▸ The dissociation conditions of hydrates of CO2/N2 and CO2/CH4 are modeled. ▸ New experimental dissociation data for CO2/N2 hydrates are reported. ▸ The developed model gives satisfactory results compared with available models.
