H2S scrubber

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.

In this study, hydrogen sulfide (H2S) removal rate by different alkali and oxidative absorbing solutions (i.e., NaOH, Ca(OH)2, NaOCl, Ca(OCl)2, and water) was compared using a packed absorption column. The results showed that NaOH solution was the suitable absorbent based on its removal efficiency, mass transfer coefficient, and overall enhancement factor.
