摘要
化学吸收法是燃后CO_2捕集的主要方法之一,本文介绍了化学吸收法脱除CO_2的系统工艺及特点,综述了CO_2吸收剂的研究现状,介绍了典型吸收剂:氨水吸收剂、氨基酸盐吸收剂、碳酸钾吸收剂的研究进展,以及新型吸收剂研究方向:混合胺吸收剂、相变吸收剂、离子液体吸收剂、纳米流体吸收剂,CO_2开关型吸收剂和新型有机胺吸收剂,并分析比较了各种吸收剂的优缺点。分析表明混合胺和相变吸收剂节能潜力较大,较其他四种新型吸收剂更为成熟,因此具有一定的工业化潜力。
Chemical absorption is one of the most mature method for post combustion CO2 capture. The current paper gives an overview of the development of solvent for CO2 capture. In addition to ammines,ammonia solutions,amino acid salts, potassium carbonate solutions are typical solvents which have been widely investigated. Many novel solvents have been proposed,for example blended amines,phase change solvents,ionic liquid, nano fluids based absorbent, switchable solvents and designer amines. The advantages and disadvantages of the solvents are introduced and among them blended amine solutions and phase change solvents are the most promising novel solvents which have great potential in decrease energy consumption.
