基于ASPEN的胺液吸收CO2过程的建模和仿真研究基于ASPEN的胺液吸收CO2过程的建模和仿真研究

摘要：本文针对胺液吸收二氧化碳（CO2）的过程进行建模和仿真，并采用ASPEN软件对其进行优化和分析。首先，介绍了胺液吸收CO2的原理和流程，并对其进行了数学描述。然后，根据吸收过程中液相和气相的物理化学特性，建立了基于质量守恒和能量守恒原理的吸收反应动力学模型。同时，引入了反应速率常数、分配系数和传质系数等参数，可以更准确地描述吸收过程中液相和气相之间的传质、反应和平衡。在此基础上，通过ASPEN软件进行仿真模拟，并对影响吸收效率的各种参数进行灵敏度分析。通过比较不同操作条件下的吸收效果，得出最佳的操作参数和工艺控制策略，以实现更高效、经济和环保的CO2捕集和碳减排。关键词：胺液吸收；CO2；建模；仿真；ASPEN
