摘要 通过对某电厂溶剂法CO2捕集中试装置开展基础溶剂(30%乙醇胺(MEA))的测试,揭示了烟气流量、贫液流量、再生温度、再生压力等关键操作条件对CO2脱除率和再生能耗的影响规律,预测了CO2脱除率90%、再生能耗4.0 GJ/t时的装置操作范围,通过选定预测操作条件的24 h连续运行验证了预测的准确性,证实了该溶剂法CO2捕集装置的可靠性,为后续其他溶剂在该装置上的测试奠定了基础。该研究方法在电厂溶剂法CO2捕集中试装置上的成功应用,大大提高了中试现场的工作效率,也将为更大规模的溶剂法CO2捕集示范工程提供宝贵的借鉴经验。

Abstract: Through performing test with benchmark solvent (30% monoethanolamine) at the slipstream CO2 capture pilot facility in a power plant,the influence of several key operation conditions such as flue gas flow rate,lean solvent flow rate,regeneration temperature,regeneration pressure on CO2 removal rate and regeneration energy consumption are investigated.Meanwhile the operation conditions for the slipstream facility to achieve a 90% of CO2 capture efficiency and 4.0 GJ/tCO2 of regeneration energy consumption are predicted.The prediction is validated via a continuous 24-hour test with the optimized conditions,which provides a baseline for other solvent assessments on this facility.The successful application of this research approach for slipstream CO2 capture pilot facility has improved the efficiency of pilot-scale testing,and will also supply with valuable experience for larger-scale slipstream CO2 capture demonstrations in the future.
Key words:  coal fired power plant    CO2 adsorption    monoethanolamine    CO2 removal efficiency    energy consumption
