Abstract

Using the CHEMCAD modeling program, a procedure has been developed for designing complex systems of rectification columns with partially and fully coupled heat and mass flows for various compositions of feed flow that vary in a wide range. The developed procedure has been implemented based on the example of close-cut separation of a three-component zeotropic system. The separation efficiency has been evaluated using two criteria, i.e., the economic (reduced economic expenses) and energy (total heat load of condensers and boilers) efficiency of simple and complex rectification systems.
