Abstract

Zeolite is a type of adsorbent used to dehydrate natural gas. Modifications were done to increase the adsorption capacity of zeolite. However, the current research focus more on low pressure process which might not be applicable with real condition of industrial scale. Hence, this research is carried out to investigate the zeolite capability for adsorption processes at high pressure condition which reflects the actual offshore operating condition. The experiment is carried out using GASTU and the range of operating condition of interest is from 10 bars to 80 bars of pressures and temperature ranging from 10 ᵒC to 80 ᵒC. Characterization of the chosen adsorbent will also be carried out to analyze the pore size, surface area, pore volumes, pore diameter, crystal form, structural information and information on hydroxyl groups attached to the adsorbent. Results shows that the micropore volume is 6.654 cm³/g while the surface area of the adsorbent is 28.959 m²/g. According to Brunauer definition, the chosen adsorbent has been categorized as Type I isotherms. The mean pore diameter of the adsorbent is 11.412 nm. Besides that, there are three elements attached to adsorbent having different diameters. Then, from dehydration of natural gas on zeolite experiment, the adsorption capacity increases with pressure. In conclusion, this research has shown that the chosen zeolite possesses high adsorption capacity which might favor adsorption to occur at effective rate.
