摘要

Successful design of refineries and chemical plants requires accurate calculation of vapor-liquid equilibria (VLE). With advances in computing power these calculations are increasingly being done by the equation of state (EOS) method. However, the interaction parameters for these EOS must be based on experimental data. The work done in this study involves measuring activity coefficients at infinite dilution for hydrocarbons and other compounds in an aromatic material such as flourene. Activity coefficients at infinite dilution are an optimum source of VLE data because solution effects are usually at a maximum at infinite dilution. An existing gas chromatograph has been extensively modified and tested to insure that reproducible infinite dilution activity coefficients can be obtained over a wide range of chromatographic operating conditions. Measurements are being made on additional systems at the present and there are plans to test other EOS.
