中文摘要 | 二氧化碳的排放最主要來自於化石燃料的燃燒。由於世界性公約的限定,未來二氧化碳的排放量勢必得降低,如何濃縮及回收煙道氣中的二氧化碳便成為解決此問題的首要之務。本研究藉由實驗探討兩種不同的雙塔式真空變壓吸附程序自煙道氣移除二氧化碳,並由脫附步驟得到濃縮的二氧化碳氣體。就脫附步驟中的二氧化碳產物濃度而言,六步驟程序可得到較四步驟程序為高的二氧化碳產物濃度,在脫附步驟中的二氧化碳產物濃度會隨檢測時間的增加而上升,二氧化碳濃度最高可達將近90%,二氧化碳的回收率則介於90%到95%之間。 |
英文摘要 | CO₂ released into the atmosphere are mainly attributed to fossil fuel combustion. The amount of CO₂ emission has to be cut down in the future due to global treaty. The concentration and recovery of CO₂ from flue gas is the first important step in solving CO₂ problem. This experimental study employs dual-bed vacuum swing adsorption (VSA), which does not generate another pollution problem, for CO₂ removal from flue gas and concentrates CO₂ in desorption stream. The comparison of two kinds of processes, four-step process and six-step process is explored. The CO₂ product concentration in desorption step in the six-step process is higher than in the four-step process. The outlet CO₂ concentration in desorption step increases with detection time. The highest CO₂ concentration can be near 90%. The recovery of CO₂ is between 90% and 95%. |
