Abstract: The study of the influence of natural gas temperature on the adsorption drying process is important, since temperature conditions significantly affect the efficiency of adsorbents and the duration of their operating cycle. Understanding these factors allows optimizing equipment operating modes, which can lead to a significant increase in economic benefits due to a reduction in the frequency of sorbent replacement and regeneration. The article considers the influence of natural gas temperature on the process of deep adsorption drying under operating conditions of gas processing plants. The results of technological studies demonstrating a change in the duration of the adsorption stage and other process parameters depending on the initial moisture content of the gas are analyzed. Data on the influence of industrial zeolite NaA characteristics on the efficiency of the drying process are presented. It is demonstrated that carrying out the adsorption process at low temperatures is accompanied by a significant increase in the dynamic capacity of the adsorbents. This causes a significant reduction in the duration of the adsorption stage, allowing a larger volume of natural gas to be processed without the need for frequent replacement or regeneration of the sorbent. Such improvement of process characteristics not only reduces operating costs, but also significantly increases its technological and economic efficiency. The obtained results can be used to develop recommendations for optimizing adsorber operation cyclograms depending on the initial operating conditions.
