Phase equilibrium studies of high-pressure natural gas mixtures with toluene for LNG applications

Experimental study of impurity freeze-out in ternary methane + ethane + benzene mixtures with applications to LNG production

“…However, once these binary interactions are characterized, the predictive accuracy of models describing solid-fluid-equilibrium (SFE) conditions for LNG-like mixtures must be examined via experiments involving higher-order mixtures such as ternary, quaternary, and multi-component systems. It is well known that the presence of other compounds in the solvent such as ethane or propane (in addition to methane) can appreciably enhance the solubility of the heavier hydrocarbons [16][17][18][19][20].…”

Natural gas density measurements and the impact of accuracy on process design

“…Thus, in terms of ternary or multi-component gas mixtures, their accuracy needs to be further tested with new high-quality experimental data [12]. Our recent studies of thermodynamic properties such as phase equilibrium [14,[21][22][23][24][25][26][27][28][29][30][31][32][33], heat capacity [34,35] and density [25,[36][37][38] clearly identified deficiencies in EOS commonly used by industry, and in several of the archival literature data to which those models have been tuned [14].…”
