資料簡介

隨著未來二氧化碳（CO2）排放量越來越有可能受到一些時髦的新工藝正在開發(fā)以從化石燃料發(fā)電廠的煙道氣中捕獲CO2。從傳統(tǒng)方法中捕獲CO2的市售方法粉煤(PC)鍋爐是利用胺基系統(tǒng)從鍋爐中吸收二氧化碳。煙道氣流，及其隨后的再生產(chǎn)生接近純的產(chǎn)品流。安另一種捕獲CO2的方法是使用氧氣而不是空氣作為氧化劑。燃燒過程，產(chǎn)生主要由CO2和H2O組成的煙氣流。除去水，可以產(chǎn)生幾乎純凈的CO2流。這種方法，稱為含氧燃料或含氧燃燒，是本系統(tǒng)分析研究的主題。

As it becomes increasingly likely that future carbon dioxide (CO2) emissions will be regulated in some fashion, new processes are being developed to capture CO2 from the flue gas of fossil fuelfired power plants. The commercially available method for capturing CO2 from a conventional pulverized coal (PC)-fired boiler is the use of an amine-based system to absorb CO2 from the flue gas stream, and its subsequent regeneration to produce a nearly pure product stream. An alternative method to capture CO2 is to use oxygen rather than air as the oxidant in the combustion process, which yields a flue gas stream composed primarily of CO2 and H2O. By removing the water, a nearly pure CO2 stream can be produced. This approach, known as oxyfuel or oxycombustion, is the subject of this systems analysis study.
