为揭示一乙醇胺( MEA)吸收法捕集CO2的机制,探寻重要参数对脱碳效率的影响情况,利用Aspen Plus建立MEA吸收烟气中CO2的系统模型。通过与某电厂脱碳系统运行数据的比对,发现该模型与实测值的拟合度较好。模型考察了吸收剂温度、烟气流量及贫液负荷等因素对脱碳效率的影响情况。结果表明:吸收剂温度越低、烟气量越小、贫液负荷越低,CO2的吸收率越高。该模型对脱碳系统的变工况运行和提高脱碳效率,起到了指导和预测作用。

In order to reveal the mechanism of monoethanolamine ( MEA) capturing CO2 and to explore the important parameters ’ influence on decarburization efficiency , the Aspen Plus was used to establish the model of MEA absorbing CO2 from the flue gas.Comparing with the operating data of a plant decarburization system indicates that this model agrees well with the measured values , and it can investigate the influence of absorbent temperature, flue gas flow and barren liquor load on the decarburization efficiency , and lower absorbent tem-perature , flue gas flow and barren liquor load can bring higher CO 2 absorption rate .This model plays a guide and predictive effect in increasing de-carbonization efficiency and de-carbonization system ’ s varying duty .
