采用两个硅胶填充柱进行变压吸附空气干燥实验。还进行了水蒸气在硅胶上的间歇吸附的测量，以获得作者的PSA模拟程序的输入数据。实验PSA结果与此计算机模拟进行了比较。模拟结果与实验结果吻合较好，解释了等温和非等温实验结果的变化趋势。在模拟中，然而，传质系数的两个或三倍大，从批量测量的传统估计使用，以获得良好的一致性。这些较大的传质系数是由最近开发的短吸附和解吸周期的方法确定的。5）模拟方法是有用的，在预测空气干燥PSA的性能。
Air drying experiments by pressure swing adsorption (PSA) were carried out, using two columns packed with silica gel as adsorbent. Measurements were also made of batch adsorption of water vapor on silica gel to obtain input data for the authors' PSA simulation program. Experimental PSA results were compared with this computer simulation. Good agreement was obtained and the trend of experimental results was well explained by simulation for both isothermal and non-isothermal cases. In the simulation, however, mass transfer coefficients two or three times larger than those estimated conventionally from batch measurement were used to obtain good coincidence. These larger mass transfer coefficients were determined by a recently developed method for short adsorption and desorption cycle.5) The simulation method is useful in predicting the performance of air drying PSA.
