Abstract: A generalized model for complex distillation processes, which taking into account both multiphase (two liquid phases) and reaction on the trays is presented in this paper. The algorithm is worked out with globally convergent Newton homotopy continuation method for solving highly nonlinear systems. The algorithm for the calculation of liquid -liquid equilibria is featured by convergence, rapidity and reliability.

摘要： 提出一个考虑塔板上既存在化学反应,又允许同时出现2个液相的复杂蒸馏过程的普遍化数学模型。采用Newton同伦延拓算法求解该模型,同时将此算法用于液液相平衡计算,尤其方便、快速和可靠。
