火电厂循环水余热用于MEA溶剂再生节能分析

为提高机组热效率，提出利用吸收式热泵回收循环冷却水余热用于碳捕集MEA溶剂再生过程。对原碳捕集系统和提取循环水余热方案进行了能耗分析对比。结果表明，该机组循环冷却水余热完全可以满足MEA溶液再生所需的低温热量，此方案可有效地回收循环冷却水余热，提高机组运行效率，减少火电机组向大气排放CO2、SO2 、灰尘等污染物，带来一定环境效益。

The Energy-saving Analysis of Waste Heat that from Circulating Water Used for the Solvent Regeneration of MEA in Power Plant

To improve efficiency of thermal unit, it will propose that the waste heat of cycle cooling water are used for MEA solvent regeneration in the carbon capture process by using absorption heat pump in this paper. Analyzing energy consumption of two schemes of carbon capture and recycling waste heat. Results show that the circulating water can meet completely the demands of low-temperature heats that are used for the absorption heat pump. It will improve the efficiency of the thermal unit and reduce the emissions of contaminants into the atmosphere,for example,co2,so2,dirt that from the thermal power unit, and bring certain environmental benefits.
