摘要(中)

本研究以模擬方法利用變溫吸附分離程序以及真空變溫吸附分離程序處理發電廠所產生之煙道氣，目的在於將二氧化碳回收以及濃縮，使之封存以減少人為造成溫室氣體的排放。其中煙道氣含量為15.03% CO2和84.97%N2的混合氣，而吸附劑為工研院綠能所製備的PEI/SBA-15吸附劑。
　　模擬程式中使用了method of lines結合finite differences、upwind differences和cubic spline approximation，再以ODEPACK套裝軟體中之LSODE程式對時間作積分，估計出下段時間的濃度、溫度及壓力，之後一直重複循環計算到系統達到週期性穩態為止。
　　本研究使用的兩種程序經變因探討後得到的最佳程序如下：變溫吸附程序最佳的操作條件為吸附溫度60 oC、進料時間400 s、自然產氣時間100 s及P/F ratio 0.15。在此條件下其結果為二氧化碳濃度47.20%，回收率93.72%。捕獲每噸二氧化碳所需能耗為3.78 GJ；真空變溫吸附程序最佳的操作條件為吸附溫度60 oC、進料時間600 s、抽真空時間600 s及沖洗時間10 s。在此條件下其結果為二氧化碳濃度90.71%，回收率90.99%。捕獲每噸二氧化碳所需能耗為2.84 GJ。

摘要(英)

In this study, the temperature swing adsorption (TSA) process and temperature vacuum swing adsorption (TVSA) process are studied to separate CO2 from power plant flue gas. The purpose of the carbon dioxide recovery and concentration is to reduce human-caused greenhouse-gas emissions. The flue gas is composed of 15.03% CO2 and 84.97% N2 gas mixture and the adsorbent is PEI/SBA-15 adsorbent, which is prepared by the Green Energy and Environment Research Laboratories, Industrial Technology Research Institute.
The method of lines is utilized, combined with finite differences, upwind differences, cubic spline approximation and LSODE of ODEPACK software to solve the problem. The concentration, temperature, and adsorption quantity in the bed are integrated with respect to time by LSODE of ODEPACK software. The simulation is stopped when the system reaches a cyclic steady state.
Two processes have been used in this study, TSA and TVSA. After the variables discussion, the best processes for two processes are as following: the best operating condition for TSA process is adsorption temperature 60 oC, feed time 400 s, vent time 100 s, and P/F ratio 0.15. The results of the best operating condition reach the purity of 47.2% and the recovery of 87.26% of CO2 with an energy consumption of 3.78 GJ/ton CO2; the best operating condition for TVSA process is adsorption temperature 60 oC, feed time 600 s, vacuum time 600 s, and purge time 10 s. The results of the best operating condition are 90.71% purity and 90.99% recovery of CO2 with an energy consumption of 2.84 GJ/ton CO2.
