Air Separation Characteristics of Pressure Swing Adsorption Apparatus using Molecular Sieving Carbon.

Simulation of Pressure Swing Adsorption Process of Butane/Air Separation in Carbon-Coated Ceramic Monolithic Adsorber

The new shaped structured adsorber, carbon monolithic adsorber, are characterized by straight parallel channels separated by thin wall, high void fraction and large geometric surface area, resulting in a low pressure drop under high flow rate and large contact area. These properties make it have the advantage on adsorption application. This study simulates the adsorption separation of 30% butan...

Investigation of carbon dioxide capture from hydrogen using the thermal pressure swing adsorption process: Central composite design modeling

In this study pre-combustion capture of carbon dioxide from hydrogen was performed using a 5A zeolite adsorber. A one column thermal pressure swing adsorption (TPSA) process was studied in the bulk separation of a CO2/H2 mixture (50:50 vol%). The adsorption dynamics of the zeolite bed were investigated by breakthrough experiments to select the suitable range for operational factors in the desig...

Extraction of Xenon Using Enriching Reflux Pressure Swing Adsorption

Measuring radioactive xenon isotopes in the atmosphere is an important technique used for monitoring within the Comprehensive Nuclear-Test-Ban Treaty (CTBT). Several process steps are needed to capture and prepare a xenon sample suitable for transfer to a nuclear detector. These processes include air drying, xenon collection, concentration, and purification. The ideal xenon sampling system woul...

Biogas Upgrading by Pressure Swing Adsorption

Producing Nitrogen via Pressure Swing Adsorption

Nitrogen gas is a staple of the chemical industry. Because it is an inert gas, nitrogen is suitable for a wide range of applications covering various aspects of chemical manufacturing, processing, handling, and shipping. Due to its low reactivity, nitrogen is an excellent blanketing and purging gas that can be used to protect valuable products from harmful contaminants. It also enables the safe...
