Vapor-liquid equilibrium measurements for design of coal gasification plants
Results are reported on vapor-liquid equilibrium compositions of two synthetic mixtures - H/sub 2/+CO+CO/sub 2/+CH/sub 4/+C/sub 2/H/sub 6/+Benzene and H/sub 2/+CO+CH/sub 4/+C/sub 2/H/sub 6/+C/sub 2/H/sub 4/+CO/sub 2/+H/sub 2/S+COS+Benzene. The equilibrium conditions investigated range from 323 to 479 K and 2280 to 19720 kPa. Based on this study, the Peng-Robinson correlation appears to be slightly better than the Soave-Redlich-Kwong correlation in predicting the phase equilibrium behavior of these complex mixtures. Both correlations are superior to the Grayson-Streed and Chao-Seader correlations. However, the Peng-Robinson correlation still shows some areas where improvements can be made. Specifically, for this six-component system it was observed that - actual hydrogen, methane, and carbon monoxide solubility in the liquid phase is greater than that predicted by the Peng-Robinson correlation under all conditions, and actual benzene, carbon dioxide, and ethane solubility in the gas phase is greater than that predicted under all conditions. 19 references, 7 figures, 10 tables.
