摘要
我国第1套燃气烟气CO2捕集中试装置成功完成3000h连续试验运行以论证吸收溶剂和工艺过程。试验结果表明：开发的燃气烟气C02捕集系统运行平稳，工艺过程稳定可靠。吸收剂具有效率高、腐蚀降解低、损耗少等特点，溶剂损耗小于0．5kg／t CO2，溶液对316L、304、2205、2507这4种合金材料的腐蚀度均小于I．65×10^-3mm／a。吸收塔尾气污染物排放水平低，其中溶剂排放〈0．17ml/m3，亚硝胺排放〈3μg／m2，未发现硝胺存在。新型的蒸汽加热-闪蒸-机械蒸汽再压缩一体化再生工艺比传统加热再生方式减少蒸汽消耗10％~25％，总再生能耗下降10％～15％。
The first CO2 capture pilot plant from simulated flue gas of natural gas combined cycle （NGCC） in China had been continuously run for more than 3000h to demonstrate absorbent and process. The test shows that the designed capture process runs stably and reliably. The developed CO2 absorbent has the advantages of high absorption efficiency, low corrosion, low degradation and low solvent loss： the solvent loss is lower than 0.5 kg/t CO2, corrosion levels for four materials of 316L, 304, 2205, 2507 are all lower than 1.65×10^-3 mm/a. the pollutants level of treated gas can achieve solvent emissions of 〈0.17 ml/m3 and total nitrosamine emissions of 〈3 μg/m3, and nitramines were not detected in any samples. Compared to traditional steam regeneration style, the novel steam-flash-mechanical vapor recompression system can reduce 10%-25% steam demand and decrease 10%-15% total energy cost for CO2 capture.
