This rigorous and effective new simulation method is developed on the concept of a simple, stable algorithm so as to ensure fast and reliable convergence for a wide range of absorption problems. The main characteristic of this method lies in the technique of solving only two objective functions for stoichiometric and enthalpy balance equations by a matrix equation requiring the inversion, only once per problem, of a large matrix consisting of the derivatives of these functions with respect to two independent variables: temperature and vapor rate. The stability of this method is demonstrated here by its capability of solving absorption problems involving both wideand narrow-boiling mixtures, a stripper, an absorber with intermediate feed and cooling, reboiled absorber, and particularly, multicomponent absorption problems with non-ideal systems. The solutions of some of these problems predicted by this method are compared with the available results and are found to be in good agreement.
