| Abstract: | The crude methanol pre-fractionator is calculated by the application of improved opposite triangle matrix technique and UNIFAC model, and crude methanol water addition, number of trays, reflux ratio and feed inlet location etc are analyzed. The calculation results indicate that the improved opposite triangle matrix technique is applicable to the simulation calculation of crude methanol fractionator. The calculated theoretical plate temperature and component concentration distribution etc are consistent with operation values. |
