RESUMO/ABSTRACT

Biogás is produced from anaerobic digestion of organic biodegradable materials. However, its application is limited as it contains impurities such as carbono dioxide (CO2), hydrogen sulphide (H2S), and other trace gases. Chemical absortion is capable of producing gas of highy methane contente above 95% and has no methane losses hence it’s widely used on large scale applications. Sodium hydroxide was used for cleaning the biogás in this study at a concentration of 1M, 2M, and 3M. The effect of concentration on absrotion and CO2 removal efficiency was studied. It was abserved that na increase in concentration lead to na increase in the absortion rate and the removal efficiency respectively. The highest removal efficency was recorded to be 66%.
