Investigating the Impact of Length of Mass Transfer Zone (LMTZ) of Packed Adsorption Unit Design and Simulation for Carbon Dioxide (CO ) Capture

Sakwe Adianimovie, Ebiundu Komonibo

Abstract

Owing to poor ambient air quality made up of dangerous air pollutants such as greenhouse gasses especially carbon dioxide (CO2) that causes global climate change from the anthropogenic activities of man, including emissions from petrol generators, therefore, this work aimed at investigating the impact of length of mass transfer zone of packed-bed adsorption unit design and simulation for CO2 capture in enhancing ambient air quality . The designed packed unit was activated carbon (adsorbent) obtained from periwinkle waste shells. And from the designed calculations, the fixed-bed has bed volume (0.01163 m3), bed diameter (0.4604 m), bed height (0.6744 m), cross-sectional area (0.158 m2) and mass transfer zone height (0.0708 m), having feedstock values into the simulation of inlet CO2 concentration (1165 ppm), gas flow rate (0.00163 kmol/s) and bulk density (429.92 kg/m3). The simulation process exhibited constant temperature (598 K), pressure (1,013 bar) and moderate build-up of CO2 adsorption capacity (0.147 mol/kg). The solid loading show that the adsorbent to CO2 interaction induces high adsorbed amount, low gas hold-up, breakthrough occurrence , long adsorption zone, solid loading trend (increases down bed), high selectivity and no displacement by other gas. And upon the determination of the impact of LMTZ on the unit, at the bed length of 0.44 m before breakthrough point , the process recorded 95.7% removal of CO2 in 501 seconds, and at 0.65 m of the bed length after the breakthrough point unit recorded 97% in 919 seconds, thus effective capture of CO2 enhancement of ambient air quality .
