“…During the processing of NG, the removal of water vapor is a fundamental and mandatory step (Kim et al, 2016). Natural gas drying is a very important process to the industry because, water vapor in gas streams can result in line plugging due to hydrate formation, reduction of line capacity due to collection of free water in the line, and a higher risk of damage to the pipeline due to the corrosive effects of water (Gholami, Talaie, & Roodpeyma, 2010;Santiago et al, 2018;Antunes et al, 2018;Rodrigues, Naccache, & Mendes, 2019;Salman, Zhang, & Chen, 2020).…”

The experimentally investigation for dehydration of gas streams in a fixed-bed adsorption column using a 4A molecular sieve was reported for the first time. Different operating conditions of the adsorption system were performed, such as flow rate (2.0, 5.0 and 8.0 L min.-1) and bed depths (10, 20 and 30 cm). A significantly decreased (p ≤ 0.05) in exhaustion time of the adsorption column was verified as a result of the increase in the flow rate. On the other hand, a significantly increase (p ≤ 0.05) in the rupture time and the mass transfer zone (MTZ) were observed when the bed depths rise. Furthermore, the experimental data were satisfactory described by the Yoon-Nelson model due to high values of correlation coefficient (R2). These results suggested the suitability of 4A zeolite molecular sieve for the dehydration of gas streams in continuous operating mode. Moreover, it could be interesting for the scientific communities and industry.
