    Abstract: 本研究針對三種不同薄膜蒸餾模組,結合太陽能加熱程序進行海水淡化作業,建立系統單位產水價格最適化設計。程序中之薄膜蒸餾模組有:氣隔式、直接接觸式及真空式三種。利用化工模擬軟體 Aspen Custom ModelerR (ACM),建立各單元模組之質量與能量平衡方程式,及各設備成本函數,並將模擬結果與文獻之實驗數據進行驗證。以最小化單位產水價格為最適化目標函數,使用ACM之“序列二次規劃可行路徑最適化方法”(Feasible Path Successive Quadratic Programming Optimization, FEASOPT ) 對各程序進行最適化求解,結果顯示在台灣地區四季之太陽能日照分佈情況下,三種薄膜蒸餾系統日間操作均可達到每小時2000公斤產水量之產能。接續完成三種程序之控制架構,建立白天與夜間之操作模式後,太陽能驅動薄膜蒸餾海水淡化系統之全年度最適化單位產水價格,以氣隔式系統 ($2.7/m3)最便宜,而直接接觸式及真空式之價格分別為 $5.4/m3與 $10.4/ m3。此最適化之氣隔式薄膜蒸餾系統建置成本 ($57,092)較直接接觸式 ($123,411)及真空式 ($350,565)之成本低。
    The objective of this research is to combine renewable solar thermal energy and seawater membrane distillation desalination systems into green processes. The units of the systems include air gap (AGMD), direct contact (DCMD) and vacuum membrane distillation (VMD) modules. In order to assess the economic design point of the process, the Aspen Custom Modeler (ACM) was used to build the mathematical model to describe each unit of solar-driven membrane distillation desalination systems. Simulation results show that the total annual costs (TAC) of air gap (AGMD), direct contact (DCMD) and vacuum membrane distillation (VMD) modules for 2000 kg/hr water production are $57,092, $123,411 and $350,565, respectively. The control structures of solar-driven membrane distillation desalination systems were built which include quality control in order to maintain the water production rate and day/night operating mode. Finally, the dynamic simulations of these systems in all seasons are demonstrated to validate the operability analysis results. The optimal unit water production costs of air gap (AGMD), direct contact (DCMD) and vacuum membrane distillation (VMD) modules are $2.7/m3, $5.4/m3 and $10.4/ m3, respectively.
