摘要
研究了气凝胶高效节能保温材料在输油站场应用的经济性。通过计算和对比气凝胶材料与传统保温材料的保温性能、初始投资费用、以及运行维护成本,发现在管道上使用气凝胶材料较传统保温材料具有较大综合优势。使用气凝胶材料所节约的能源和运行维护费用(主要指更换传统保温层的材料和人工费用),可在2~4年内超过初期多花费的投资。在随后的服役过程中,可持续因能源节约和减少保温层更换次数为管道运营商节省开支。此外,当管道内外温差较大、年加热时长较长、加热燃料或电能涨价时,使用气凝胶材料的效果更好。总之,在管道上使用气凝胶材料将以节能降本的方式为管道运营商增加效益。
The economical efficiency of high performance aerogel thermal insulation material applying on surface pipelines in oil transportation stations is studied.The thermal insulation efficiency,initial investment and maintenance cost of aerogel material and traditional thermal insulation material are calculated and compared.It is found that the application of the aerogel material on pipelines is comprehensively better than that of traditional thermal insulation materials.The energy and operation expense(mainly refers to changing material of traditional insulating layers and cost of labor)saved by applying aerogel material could cover the extra initial investment in2-4 years,and it could save energy and renewal cost persistently and considerably in its subsequent service life.Moreover,its effect would be better when the temperature difference between inside and outside of the pipeline is bigger,when yearly heating time is longer and when price of heating fuel or electric energy rises.Generally,applying aerogel thermal insulation materials on pipelines would increase benefits for pipeline companies by means of energy saving and cost reducing.
