Abstract
Some aspects of the multicomponent distillation modelling are analysed and discussed. A highly simplified noniterative mathematical model is offered for calculation of the top and bottom product compositions. It can be successfully adapted to a working distillation column on the base of easy obtainable measurement data related to the lower or upper cut points of the products. Being extremely fast, the model can be used for optimisation of the mode of operation and on-line control of crude oil separation and other multicomponent distillation processes.
