Abstract

Two different types of problems are approached by connecting simplified molecular models with equations of state (EOS). For aqueous-organicsolutions of gases chemically reacting with solvent, special techniques to handle electrostatic and nonelectrostatic interaction contributions in the calculation of liquid composition and fugacity coefficientsare applied for modeling VLE. A modified hole model and the Soave-Redlich-Kwong (SRK) EOS are utilized to describe solubility of gases in water-alkanolamine-acid gas (CO2, H2S) mixtures. A polydisperse versionof a thermodynamic micellization model proposed earlier is formulatedand applied to describe asphaltene phase drop-out from crude oils. (C) 1998 Elsevier Science B.V.
