Assessment of the Factors Affecting the Service Lifespan of Silica Gel

To present the results of research conducted to analyze the influence of temperature and relative humidity of the atmospheric air entering the compressor system, as well as the required purity class after adsorption drying on the service lifespan of the KSKG brand adsorbent. To determine the feasibility of their use. Methodology: In order to ascertain the extent to which the selected physical parameters of atmospheric and compressed air and its statutory purity class at the compressor outlet influence the adsorbent service lifespan, a methodology for calculating the adsorbent lifespan was tested, considering the above-mentioned factors. Methods: The results obtained were compared and analyzed. Following this, the results were graphically visualized. Subsequent conclusions and recommendations have been formulated to substantiate the potential use of the adsorbent under study according to the criterion of “service lifespan”. Practical significance: The findings of the aforementioned studies provide a solid foundation for the selection of an adsorbent that is optimally suited for utilization in adsorption drying technology, particularly within pneumatic systems employed in railway rolling stock and railway industry enterprises. This selection will empower the implementation of a programme aimed at enhancing resource conservation and mitigating the adverse environmental impact by decreasing the amount of waste generated from used resources.
