摘　　要：提出一种新算法Newton同伦—同时校正混合法模拟三相精馏过程,该算法将同时校正法有机地嵌入同伦法中,采用同伦弧长微分法求解,在保持同伦算法大范围收敛特性的同时,提高了计算效率。采用Michlesen稳定性判据作为液相稳定性判据。以正丙醇—正丁醇—水物系三相精馏塔为例,验证了算法的有效性。There are many three- phase rectification processes in petrochemical industry. Simulating process is very important for chemical technology separation. In this paper, a new algorithm named New- ton - homotopy - simultaneous - correction mixed algorithm is put forward which combines the advantages of global convergence and quick convergent rate. The liquid - phase stability analysis is on the basis of the Michlesen stability analysis. Acrylonitrile - acetonitrile three - phase extractive rectification is simulated successfully by new algorithm.
