Abstract
Effect of Bed Porosity on CO2 and CH4 Adsorption inside Packed Bed Column for CO2-CH4 Gas Mixture
Highlights
The increase in atmospheric concentration of carbon dioxide is proving to be detrimental for the environment and will result in global climate change [1]
Computational Fluid Dynamics (CFD) approach has been used to determine the mass transfer phenomenon of CO2/CH4 gas mixture inside the high pressure volumetric analyzer (HPVA) packed bed filled with the adsorbent
It is due to the reason that more amount of gas molecules can attach to the surface of the adsorbent when it is compact at low porosity values
Summary
The increase in atmospheric concentration of carbon dioxide is proving to be detrimental for the environment and will result in global climate change [1]. It is estimated that since the time of industrial revolution to 2015, atmospheric CO2 concentration has risen to a value of 401ppm [2]. This trend will continue to rise if anthropogenic sources of emission are not regulated properly. Different techniques have been proposed in order to capture CO2 from flue gases on large scale. These techniques include cryogenic distillation, membrane purification, and absorption using liquids and adsorption by employing solid adsorbents [3]. For this work, activated carbons are used as an adsorbent to study the adsorption process. Computational Fluid Dynamics (CFD) approach has been used to determine the mass transfer phenomenon of CO2/CH4 gas mixture inside the high pressure volumetric analyzer (HPVA) packed bed filled with the adsorbent
