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。

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.
