The first industrial-scale CO 2 capture plant in China has been demonstrated at Huaneng Beijing power plant has shown that this technology is a good option for the capture of CO 2 produced by commercial coal-fired power plants. The commissioning and industrial tests are introduced in this paper. The tests show that in the early stages of the passivation phase, the concentration variations of amine, anti-oxidant and Fe 3+ are in the normal range, and the main parameters achieve the design value. The efficiency of the CO 2 capture was about 80–85%, and by the end of January 2009 about 900tons of CO 2 (99.7%) have been captured. The equipment investment and consumptive costs, including steam, power, solution and others, have been analyzed. The results show: the cost of the absorber and the stripper account for about 50% of main equipment; the consumptive cost is about 25.3US$ per metric tons of CO 2 , of which the steam requirement accounts for about 55%; the COE increased by 0.02US$/kWh and the electricity purchase price increased by 29%.
