Analysis of global approaches to the simulation of counter-current separators

The status of research and development of simulation of counter-current separation processes via global approach is discussed. A general numerical method for calculation of separation equipment should be able to handle easily various modifications in configuration. Global solution of all governing equation results in a procedure which is flexible enough to perform all types of calculations. Classification of difficult separation problems indicates which one should be solved by a global approach. A general strategy of calculation of multicomponent counter-current separation processes via a global approach is presented.
