Combined heat and mass exchanger network, Controllability, Methanol solvent process, Passivity concept


This article mainly focuses on the application of the combined heat and mass exchanger network (CHAMEN) on Methanol solvent process. CHAMEN analyses heat exchanger network (HEN) and mass exchange network (MEN); simultaneously. HEN was designed by Aspen Energy Analyzer, while MEN was analyzed by GAMS. Then, optimal controllers were designed by the passivity concept to guarantee the general process stability. The dynamic model was generated for all variables of the unit in the state space domain. Subsequently, the state space model of CHAMEN was formulated investigated by the concept of passivity. Analyses by the passivity index can indicate the passivity of process. Also, this process with HEN and CHAMEN was investigated the performance of the system with and without controllers. Moreover, the responsibility of controllers was analyzed based on the concept of passivity and compared with auto tune method by Aspen Dynamic. Likewise, the passivity tune presented the better robust control over conservation method by auto tune. Finally, we explored future challenges in this field of apply to another process.
