Breakthrough analysis of continuous fixed-bed dehydration of gas streams using 4A zeolite molecular sieve

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