【摘要】：近年來(lái)由于CO2的大量排放所導(dǎo)致的溫室效應(yīng)對(duì)全球氣候和自然環(huán)境造成了一系列不利影響。在全球節(jié)能減排的大環(huán)境下,作為CO2第二排放大國(guó),將面臨巨大的減排壓力。CO2捕集與封存技術(shù)(CCS)是以燃煤為主的能源結(jié)構(gòu)下CO2減排的有效手段�；趩我掖及坊瘜W(xué)吸收法(MEA)的燃燒后碳捕集技術(shù),是具有發(fā)展前景捕集技術(shù)。本文對(duì)以機(jī)組抽汽為碳捕集系統(tǒng)吸收劑解吸提供熱源和以太陽(yáng)能提供解吸熱源的機(jī)組熱力系統(tǒng)特性進(jìn)行了研究。主要研究?jī)?nèi)容和創(chuàng)新如下： 1、分析了基于單乙醇胺(MEA)捕集CO2吸收劑解吸能耗特性,研究了以機(jī)組抽汽為吸收劑解吸熱源的三種方案,確定了可行方案并對(duì)系統(tǒng)進(jìn)行了優(yōu)化。研究了基于MEA的CO2吸收劑解吸能耗特性,得到了不同質(zhì)量分?jǐn)?shù)下吸收劑的再生能耗,對(duì)碳捕集電站的能量流、質(zhì)量流進(jìn)行分析,研究了以機(jī)組抽汽為吸收劑解吸熱源的三種方案,確定了可行方案�；�(?)分析模型和(?)成本分析,分析了系統(tǒng)的不可逆程度,考慮能量成本和非能量成本,研究了系統(tǒng)各組件熱經(jīng)濟(jì)學(xué)成本的分布。 2、提出了基于碳捕集的太陽(yáng)能-燃煤機(jī)組三種集成系統(tǒng),分析了集成系統(tǒng)的熱力學(xué)性能,研究了系統(tǒng)的不可逆程度及(?)成本分布規(guī)律。由于吸收劑解吸熱需求量大,完全由機(jī)組抽汽提供解吸熱,將使機(jī)組的能量流分布有較大改變,對(duì)機(jī)組經(jīng)濟(jì)安全運(yùn)行產(chǎn)生不利影響。為此,本文提出了三種基于碳捕集的太陽(yáng)能-燃煤機(jī)組集成系統(tǒng),并對(duì)集成系統(tǒng)進(jìn)行了可行性分析,研究了系統(tǒng)的熱力學(xué)特性和炯成本分布規(guī)律。 3、構(gòu)建了基于碳捕集的太陽(yáng)能-燃煤機(jī)組集成系統(tǒng)的熱經(jīng)濟(jì)學(xué)優(yōu)化模型,對(duì)集成系統(tǒng)進(jìn)行了技術(shù)經(jīng)濟(jì)性分析。分析了太陽(yáng)能集熱場(chǎng)為碳捕集系統(tǒng)提供熱源時(shí)集成系統(tǒng)的熱經(jīng)濟(jì)學(xué)特性,建立了以熱經(jīng)濟(jì)學(xué)成本最小為目標(biāo)函數(shù)的數(shù)學(xué)模型,對(duì)集成系統(tǒng)的能流進(jìn)行了優(yōu)化研究,分析了集成系統(tǒng)的熱經(jīng)濟(jì)學(xué)成本分布規(guī)律。對(duì)所研究系統(tǒng)進(jìn)行了技術(shù)經(jīng)濟(jì)評(píng)估,研究了發(fā)電成本、CO2減排成本隨碳稅收及售價(jià)的變化。
