Abstract:

Biogas is produced through anaerobic fermentation process of organic matter and it contains CH4, CO2, H2S and other gases. The main combustible gas in biogas is CH4 and the presence of other gases reduces the calorific value of biogas, hence for obtaining better performance of engine it is essential to remove CO2 and H2S present in raw biogas. The dry absorbent based biogas purification system was developed and its performance was evaluated. The major components of the biogas purification system include CO2 scrubber, H2S scrubber, biogas analyzer, biogas flow-meter, biogas pump, pressure gauge, control valve and frame for holding the scrubber. The performance of the purification unit was evaluated for purification of biogas at bed heights of 15 cm, 20 cm and 25 cm with maintaining flow rates of 1.2 m3/h, 1.5 m3/h and 1.8 m3/h. The purification unit was therefore observed to performed best at the optimum bed height of 20 cm and flow rate 1.5 m3/h. The result of the study showed that the purification unit could purify the biogas satisfactorily. The payback period of the investment involved for the biogas purification unit was workout. The total cost of biogas purification system was Rs. 41000 with payback period of the investment of 3 years, 2 months and 13 days.
