Performance analysis of a pressure swing adsorption unit in removing biogas impurities using zeolite 13X

Biogas Upgrading by Pressure Swing Adsorption

Adsorption characteristics of ammonium ion by zeolite 13X.

With synthetic wastewater, lab-scale batch experiments and column experiments were carried out to investigate the adsorption characteristics of ammonium ion by zeolite 13X which is a hydrothermally synthetic byproduct accompanied with preparation of potassium carbonate from insoluble potash ores. The Langmuir and Freundlich models were applied to describe the equilibrium isotherms for ammonium ...

Dynamic Modeling of Nitrogen Adsorption on Zeolite 13X Bed

Oxygen is one of the most important products in chemical industries. This chemical element is used in various processes such as: refinery industries, manufacturing metal and other industrial operations. For instance, oxygen with high purity is utilized in different chemical processes like: steel construction, paper industries, wastewater treatment and glass production. In 1907, oxygen was produ...

Heat and Mass Transfer Characteristics of a Zeolite 13x/cacl2 Composite Adsorbent in Adsorption Cooling Systems

The performance of the adsorption cooling system using the zeolite 13X/CaCl2 composite adsorbent was studied using a numerical simulation. The novel zeolite 13X/CaCl2 composite adsorbent with superior adsorption properties was developed in previous studies [11]. It has high equilibrium water uptake of 0.404 g/g between 25C and 100C under 870Pa. The system specific cooling power (SCP) and coeffi...

Investigating the Performance of Amine-Grafted Silica-Base Adsorbents in CO2 Removal from a Natural Gas Stream Using a Diffusion Based Mathematical Model

Abstract:  In this study adiffusion based mathematical model was developed to compare the performance of amine-grafted adsorbents with that of 13X zeolite in a fixed-bed adsorption tower which is used to capture CO2 from both humid and dry nitrogen stream under industrial conditions. The results show that the performance of amine-grafted adsorbent and 13X zeolite is almost the same in the dry ...
