In this study, the concept and model of hybrid heat-integrated distillation system (HHIDiS), which have been signalized in our previous works, have been revisited in more details. Here, we have focused on modeling of a heat and mass exchanger (HME) unit which can be applied for heat-integrated thermal separation process. In this paper we would like to propose the design calculation procedure for a dedicated HME in an exemplary binary distillation HHIDiS unit. A design calculation method has been proposed taking into account all crucial thermal-flow phenomena and basic energy-saving aspects of HME operation. The calculation procedure is based on widely verified theories: 1)thermal resistance theory for heat transfer calculations, 2)the concept of theoretical tray for mass transfer, and 3)finite volume method for two-phase flow hydraulic calculations. Scalability of the proposed approach has been improved by employing a hybrid heat integrated distillation system (HHIDiS) consisting of a single classic rectifying and stripping units and one or multiple HMEs for separation of binary or multi-component mixtures respectively. Novel channel geometry has been proposed to induce necessary two-phase flow pattern. One of benefits of presented HME and HHIDiS its reduced apparatus height and no requirements for dedicated equipment (e.g. compressors).
