“…Answering these questions using equilibrium stage models and nonlinear equilibrium functions requires solving challenging mixed integer nonlinear programing problems. In the last years remarkable progress has been achieved in this area and the mathematical tools have been developed . These theoretical concepts will be increasingly applied in future to wider apply the powerful countercurrent principle in separation science, as for example in the case studies discussed above.…”

The implementation and exploitation of countercurrent movement between different phases is a well‐established principle to enhance the performance of separation processes. The improvements are essentially due to the establishment and application of more favorable driving forces compared to co‐current operation. The success of dedicated multistage countercurrent distillation processes has been a key motivator for the development of many other principles of countercurrent separation processes. This promoting aspect was strongly supported by the availability of graphical solutions of the underlying mass balance equations, e.g. the McCabe‐Thiele diagram. Selected applications of countercurrent separation processes are presented, which demonstrate extensions exploiting spatial and temporal sub‐structures and additional phase changes.

The constant molar overflow (CMO) framework, while useful for shortcut distillation models, assumes that all components have the same latent heats of vaporization. A simple transformation, from molar flows to latent‐heat flows, allows shortcut models to retain the mathematical simplicity of the CMO framework while accounting for different latent heats, resulting in the constant heat transport (CHT) framework for adiabatic distillation columns. Although several past works have already proposed this transformation in the literature, it has not been well utilized in recent times. In this article, we show the utility of this transformation in upgrading various applications such as identifying energy‐efficient multicomponent distillation configurations based on heat duty rather than surrogate vapor flow. The method transforms the diagram to a diagram. Furthermore, we derive new and insightful analytical results in distillation, such as cumulative latent‐heat stage fractions having monotonic profiles within a distillation column under the CHT framework.
