Abstract:

采用一乙醇胺(MEA)进行燃煤电厂烟气脱碳是目前比较成熟和可行的技术,但是存在再生能耗高的严重缺陷。胺法脱碳系统流程改进及优化能有效降低再生能耗。应用AspenPlus软件基于速率模型对传统胺法脱碳流程及其改进流程进行模拟研究。这些改进的流程包括吸收塔中间冷却流程、富液分流流程、贫液蒸汽再压缩流程、分流流程及富液分流与贫液蒸汽再压缩整合流程。研究结果表明:富液分流与贫液蒸汽再压缩整合流程节能效果最好,和传统流程相比再生能耗及等量功分别下降28.2%和11.9%。节能效果其次的是富液分流流程,再生能耗和等量功分别下降19.3%和11.8%。贫液蒸汽再压缩流程使再生能耗下降了14.1%,而等量功只下降了4.1%。吸收塔中间冷却流程和分流流程节能效果比较有限。
