摘要
利用Aspen Adsorption模拟氯化氢吸附脱微量水过程。通过吸附平衡试验数据估算吸附等温线的常数项,用简化的单塔模型进行了穿透曲线的模拟,得到吸附塔内空隙中水的浓度分布以及塔内吸附剂的吸附量随时间的变化情况,可以看到传质区在轴方向上移动;进一步研究了传质系数和操作压力的变化对穿透曲线的影响,变化趋势与文献报道一致。
Adsorption is now broadly used in air separation,hydrogen production,dehydration of gases and other areas.Aspen Adsorption is specifically designed for the simulation of adsorption process.In this paper,hydrogen chloride dehydration process was simulated with Aspen Adsorption,parameters of isotherm were estimated,breakthrough curve,the water concentration in the bed void and the loading of adsorbent at different time were calculated in the simulation.Variations of breakthrough curve caused by changing of mass transfer coefficient and pressure were studied respectively and the result was consistent with previous work.
