摘　　要：以富氧燃烧碳捕集技术为基础,开展CO_2压缩纯化技术研究,搭建了300t/a CO_2压缩试验平台,在该平台上开展各种体积分数CO_2的压缩试验,寻找最佳运行参数.结果表明:当CO_2体积分数为80%时,液化温度为-30℃、压力为3.0 MPa是最优的液化条件,在该条件下CO_2液化率较高(81.86%),液体CO_2消耗电功最低为1 273kJ/kg,液体CO_2纯度大于99%;该平台可协同脱除NOx和SO_2等污染物.Using the carbon capture technology based on oxy-fuel combustion, CO2 compression and purification experiments were conducted on a 300 t/a first self-developed test platform at different CO2 concentrations to find the optimal operation parameters. Results show that when the volumetric fraction of CO2 is 80%, the optimum liquefaction temperature and pressure would be -30℃ and 3.0 MPa, respectively, in which case the CO2 liquefaction rate would be up to 81.86 %, with power consumption low to 1 273 kJ/kg and the final CO2 purity up to 99%. The platform can be used to simultaneously remove NOx, SO2 and other pollutants.
