Abstract : Biogas is increasingly acknowledged as a sustainable and clean energy source generated from the anaerobic digestion of biodegradable organic materials. It is anticipated that biogas will play a significant role in replacing traditional energy sources. The primary components of biogas are methane (CH4) and carbon dioxide (CO2), along with various contaminants present in differing amounts, such as ammonia (NH3), water vapor (H2O), hydrogen sulfide (H2S), methyl siloxanes, nitrogen (N2), oxygen (O 2), halogenated volatile organic compounds (VOCs), carbon monoxide (CO), and hydrocarbons. Biogas is commonly used as fuel for engines or as a precursor for the production of chemicals, hydrogen, and synthesis gas. Certain applications necessitate a specific level of purity in biogas. The presence of trace contaminants can adversely impact engine performance, making the removal of impurities, particularly H2S and CO2, crucial for enhancing biogas quality and its effectiveness in various applications. Additionally, this removal process is essential to comply with established gas specifications for use as vehicle fuel or for injection into natural gas networks. Various methods for cleaning and upgrading biogas have been identified, each differing in functionality, efficiency, and the quality of input gas required. The extraction and absorption of hydrogen sulfide (H2S) from biogas is crucial for enhancing the quality of this renewable energy source and mitigating environmental impacts. This study explores the utilization of the iron chelate method for effective H2S removal and simultaneous sulfur production. The process involves the reaction of H2S with iron chelates, leading to the formation of stable iron sulfides. Laboratory experiments demonstrate the efficiency of this method under varying conditions of temperature, pressure, and pH. The results indicate that the iron chelate method not only achieves high absorption rates of H2S but also facilitates the conversion of H2S into elemental sulfur, thus offering a dual benefit of waste reduction and resource recovery. Economic assessments suggest that the implementation of this method in biogas plants could enhance sustainability and profitability. This research highlights the potential of the iron chelate method as a viable solution for H 2S management in biogas utilization, contributing to cleaner energy production and sulfur recycling.
