    摘要: 本論文提出一創新之裝置,係針對已提出之併合熱與物質交換薄膜模組(Hybrid heat and mass exchange membrane module)之修正設計。此設計使用殼管式多膜管裝置,液相以落膜方式於膜管外與氣相進行熱質傳,熱交換流體於膜管內與管外之氣相或液相進行熱傳。應用此設計之蒸餾塔,即HMEDiC (Heat and mass exchange distillation column),屬於非絕熱(Diabatic)操作,可獲接近熱力學可逆之操作,提高能效。本論文針對氨水系統與苯-甲苯系統完成了HMEDiC之模擬分析研究。模擬分析使用Aspen plusR程序模擬軟體,配合以Fortran程式語言撰寫之嚴謹熱質傳數學模式,並利用FLUENT軟體進行流力分析,決定最小膜厚。
    An innovative device is proposed which is a revised design of a previously reported hybrid heat and mass exchange membrane module. The revised design make use of shell and tube type module. In the module, liquid forms a falling film at the tube outside and contacts with the shell side vapor phase, besides, heating or cooling fluid flows inside the membrane tube for heat exchange with the tube outside liquid or vapor phases. The module acts as a distillation, named HMEDiC (Heat and mass exchange distillation column) is investigated. The diabatic operation allows approching to thermodynamic reversible condition and increasing of energy efficiency. Applications of HMEDiC on ammonia-water and benzene-toluene systems are studied. For the HMEDiC, a rigorous mathematical model established on Aspen Plus/sup R/ with attached Fortran program is developed. Minimum flowrate required for forming a complete liquid film around the tube outside is determined by using the CFD package, FLUENT.
