資料簡介
自1970年《潔凈空氣法》通過以來,燃煤電廠在減少硫和氮氧化物、顆粒物質(zhì)和汞的排放方面繼續(xù)取得重大進(jìn)展。然而,在不久的將來,也有可能控制二氧化碳(CO2)的排放以應(yīng)對氣候變化。認(rèn)識到當(dāng)前的二氧化碳 美國能源部的國家能源技術(shù)實(shí)驗(yàn)室(DOE/NETL)已經(jīng)發(fā)起一項(xiàng) 研究和開發(fā)(R&D)計(jì)劃專門針對燃燒后和氧氣捕獲技術(shù),這些技術(shù)可以改造成現(xiàn)有的燃煤電廠,并經(jīng)過精心設(shè)計(jì) 種植新植物.作為現(xiàn)有植物、排放和捕獲(EPEC)計(jì)劃的一部分正在執(zhí)行的DOE/NETL努力的目標(biāo)是開發(fā)先進(jìn)的CO2捕獲 以及用于現(xiàn)有和新型燃煤電廠的壓縮技術(shù),當(dāng)兩者結(jié)合在一起時(shí),能夠以低于35%的成本增加90%的CO2捕獲 電(COE)。為了開發(fā)多種能夠滿足成本和性能目標(biāo)的CO2捕集技術(shù)方案,已經(jīng)制定了積極的研發(fā)計(jì)劃。 到2020年達(dá)到商業(yè)規(guī)模。
Coal-fired power plants have continued to make significant progress in reducing emissions of sulfur and nitrogen oxides (SOx and NOx), particulate matter, and mercury since passage of the 1970 Clean Air Act. However, there is a possibility that carbon dioxide (CO2) emissions could also be regulated in the near future to address climate change. Recognizing that current CO2 capture technology is not cost-effective and has not been demonstrated at scale, the U.S Department of Energy’s National Energy Technology Laboratory (DOE/NETL) has initiated a research and development (R&D) program directed specifically at post- and oxy-combustion CO2 capture technologies that can be retrofit to existing coal-fired power plants, as well designed into new plants. The goal of the DOE/NETL effort, which is being carried out as part of the Existing Plants, Emissions and Capture (EPEC) Program, is to develop advanced CO2 capture and compression technologies for both existing and new coal-fired power plants that when combined can achieve 90 percent CO2 capture at less than a 35 percent increase in cost of electricity (COE). An aggressive R&D plan has been established in order to develop multiple CO2 capture technology options, capable of meeting the cost and performance target, at a commercial scale by 2020.
