Bio-Gas Process Intensification

Chemical Engineering

Biogas is formed from anaerobic digestion of bio- logical wastes which is a renew-able energy resource. Typical biogas contains 50 - 60 % methane, 30-45 % Carbon dioxide, moisture and traces of hydrogen sulphide. Reducing the content of CO2 will significantly improve quality of biogas. Normally biogas usage is in the domestic way in the household way and upto certain level in the commercial level. In the field of biogas upgrading there are five convention technologies used for removal of CO2,this are commonly named as physical and chemical adsorption, membrane separation, cryogenic separation, chemical conversion method and pressure swing adsorption. The biogas production is influenced by many factors Car- bon/Nitrogen Ratio, Temperature, pH Value, Loading Rate, Hydraulic Retention Time, Toxicity etc some other factor affecting the biogas production Agitation, additives and season effect. We are going to install the biogas plant setup and are willing to perform previous experimental achieved target for biogas setup earlier. To investigate effect of pressure on biogas production .We can use pressure swing adsorption to upgrading CH4 in biogas as anaerobic co-digestion process by using agricultural wastes. Biogas quality is increase by using low cost adsorbent. In comparison with biogas and CNG, experimental reviews give idea about usage of biogas over CNG. Methane content is about 95% that can be used as fuel for vehicles, engines and gas turbines to produce electricity.
