摘要
以水-乙醇混合蒸气在4A分子筛上的吸附为体系,对固定床气相等温吸附过程进行研究.建立了改进的混合池模型及相应的数值解法.模型中考虑了气速的变化、轴向混合及传质阻力对过程的影响.并对上述吸附过程进行了模拟计算,计算结果与实验值吻合良好.
The separation of water-ethanol mixture by vapor phase adsorption on 4A molecular sieves was investigated theoretically and experimentally. An improved mixing pool model was proposed with consideration of axial mixing, varying gas velocity and mass transfer resistance. The numerical solution of proposed model was also presented. The predicted breakthrough curves agreed well with the experimental results.
