In many industrial processes compressed air free from traces of water vapour is essential. Adsorption dryer with heatless regeneration is used to treat air after compression to ultra-low dew point. A simple step by step design procedure for this dryer is presented. In this study, the adsorption dryer is developed based on layout design procedure, and optimal parametric conditions are obtained based on experimental design. Then the effect of process parameters on adsorption performance is studied for optimal conditions. The purge air required to achieve a varied range of pressure dew point of dry air at required operating pressure is suggested. The results revealed that a heatless regenerated adsorption system is suitable for the applications which involve feed air inlet temperature ranging from 25 to 45 °C, feed air operating pressure ranging from 5 bar, and pressure dew point of product dry air ranging from -40 to -70 °C.

在许多工业过程中，不含微量水蒸气的压缩空气是必不可少的。采用无热再生吸附式干燥机，将压缩后的空气处理至超低露点。介绍了该干燥机的简单分步设计程序。在本研究中，吸附式干燥器是根据布局设计程序开发的，并根据实验设计获得最佳参数条件。然后研究工艺参数对吸附性能的影响以获得最佳条件。建议使用所需的吹扫空气，以在所需的工作压力下实现不同范围的干燥空气压力露点。结果表明，无热再生吸附系统适用于进料空气入口温度范围为 25 至 45 °C 的应用，
