QBasic语言在多组分精馏全塔计算中的应用

Application of QBasic program on the caculation of multicomponent distillation

为了研究多组分精馏过程中有关量的计算,采用平衡级理论模型方程组(MESH方程组),分析了多组分精馏过程全塔的模拟计算,并通过计算实例探讨了QBasic语言编程方法在多组分精馏过程模拟计算中的应用.结果表明,应用QBasic语言编程进行多组分精馏过程全塔计算既快速、稳定,又提高了学生的微机编程能力.

In order to overcome the shortcoming of the complexity and tedious calcuation process, based on MESH equations and analyzing the calculation of muhicomponent distillation, the paper described a simple, stable and rapid calculation program of muhicomponent distillation based on QBasic language, and gave a practical applied example. Meanwhile, if the method is applied in teaching, it would improve students＇ capacity of the program.
