| Abstract: | Phase equilibria of a mixture of long-chain polyunsaturated fish oil fatty acid ethyl esters (FAEEs) with carbon dioxide were measured at 313.2 and 343.2 K, with ethane at 314.0 and 344.6 K, and with ethylene at 290.9 and 318.6 K. The temperatures correspond to reduced gas temperatures of approximately 1.03 and 1.13. The experimental pressures range from 1.6 to 25 MPa. The FAEE mixture is rich in eicosapentaenoic acid ethyl ester (EPA, 52.5 wt.%), and docosahexaenoic acid ethyl ester (DHA, 36.1 wt.%), and a total of 10 components were identified. The experimental temperatures, pressures, solubilities, mass fractions, and calculated equilibrium ratios are reported in tables and graphs. The mass fractions and the equilibrium ratios are reported on a solvent-free basis. |
