| Summary: | Nowadays, the continuously increasing diminution of conventional fossil fuels has increased the interest of the
research and development sectors in finding green and renewable supplements. A momentous attention has
been given to the production of biogas via the anaerobic digestion of biomass. Biogas major components are
methane, carbon dioxide and traces of hydrogen sulfide, ammonia and nitrogen. Hydrogen sulfide and other
impurities are usually removed in a process called biogas purification. Biogas upgrading process is the
process by which carbon dioxide (composing 40% of the biogas) is removed. In this study chemical
absorption process for upgrading biogas was performed using 3 different solvents (sodium hydroxide, monoethanolamine
and ammonia). The three different solvents have shown great ability in absorbing carbon
dioxide as well as hydrogen sulfide using a lab scale packed column absorber-apparatus. The lab scale
apparatus is designed to manipulate the different process parameters of liquid/gas flow ratio, column height
and solvent type. Varying the different process parameters a biogas purity up to 93.3% methane content was
obtained. |
