It is impossible to separate styrene from a C 8 distillate in an ethylene plant by conventional distillation because the difference of boiling point between styrene and o-xylene is only 0.8°C. If dimethyl acetoamide is adopted as an extractive agent, the relative volatility of styrene and o-xylene becomes higher, and we can industrially separate styrene from C 8 distillate. From vapor liquid equilibrium data of dimethyl acetoamide, styrene, o-xylene and m-xylene, Wilson parameters were determined and several methods of distillation calculation with four components computer programming were made. The improved Amundson method was most beneficial for the case study of distillation calculation. With computer programming, design parameters such as theoretical plate number, feed plate, reflux ratio and solvent ratio were studied. We also experimented with extractive distillation with a 100 plate, Oldershaw type distillation tower and compared the data with calculated results. Experimental results were consistent with calculated results if we adjusted the efficiency of the distillation tower and its internal reflux.
