| Abstract: | The persent paper describes studies on the remoral of CO_2 and H_2S from biogas by liquid ammonia method. The result show that the liquid ammonia method is effective for the removal of CO_2 and H_2S from.biogas. The CO_2 removal rate is up to 90.3%, and the H_2S removal is as hish as 99.9%. The content in biogas increased to more than 90% after CO_2 is removed, hence the cost methane for biogas storage is decreased by one third. The study on process condition and operating parameters for the removal of H_2S are also described. |
