【Abstract】 The new group contribution equation of state (VDW-GC) developed by authors has been applied to the prediction of gas-solid, gas-solid-solid, gas-liquid and gas-liquid-Iiquid equilibria related to supercritical fluid extraction processes. The test results indicate, even using the group interaction parameters determined from binary vapor-liquid equilibrium data, encouraging results were obtained.更多还原
