摘要：

A global approach to the calculation of nonadiabatic isobaric multiple liquid vapour equilibrium flash is suggested. The structure of the system of equations is adaptively changed with respect to suggested engineering-oriented rules. The resulting set of equations is solved by the Newton Raphson method. Results of two examples (equilibrium mixtures of the type G-L-L and G-L-L-L) show the efficiency of the algorithm.
