Abstract
In this study, hierarchical NaP zeolite was prepared for dehydration of a wet nitrogen gas stream using an adsorption system. Hierarchical NaP zeolite was synthesized via an easy hydrothermal process and characterized using several techniques such as scanning electron microscopy (SEM), X-ray diffraction (XRD), BET surface area analysis and Fourier transform infrared (FT-IR) spectroscopy. An adsorption system comprising a desiccant packed column, humidity analyzer, and dry and wet gas cylinders was designed to evaluate the adsorption behavior of the synthesized NaP zeolite. Results indicated that hierarchical structure of NaP zeolite made a high surface area for water removal from a non-corrosive gas stream at ambient condition as it could reduce the water content of the gas from an initial concentration of 53 ppmv to approximately 5 ppmv after just one minute of the experiment.
