摘　　要：以胜利电厂燃煤锅炉的3万t/a烟气CO2捕集系统为研究对象,对系统建设投资、运行费用(直接与间接运行费用)的组成及比例,以及经济效益进行计算分析。结果表明,系统的捕集纯化部分占总建设费用的50%以上,而存储部分仅为1/10左右;在运行费用中,直接运行费用占3/4以上,其中以电和蒸汽的费用投入最大;间接运行费用所占比例较小,且各项目费用分摊较均匀;系统投资的经济性随CO2捕集成本的增加而降低,当捕集成本达到400元/t以上时,基本无利润。胜利电厂锅炉CO2捕集系统的利润率约为15%。The composition and proportion of construction investment and operation cost(including direct and indirect running cost),as well as the economic benefit,for a CO2 capture system were calculated,taking the 30 000 t/a capture system in coal fired boiler of Shengli Power Plant as the object.Results show that,the cost of trapping and purification section accounts for more than 3/4 of the construction investment,but storage section only for 1/10.For the operating cost,direct cost occupies more than 3/4 of the total,in which the electricity and steam spend the most;indirect cost is of small proportion,in which the cost-sharing of each project is uniform.As the cost of CO2 capture increasing,the profit rate of the system will decrease and turn to zero when the capture cost reaches 400 yuan/t and above.For the Shengli Power Plant,it is about 15%.
