Efficient Techniques of Transformation from Biogas to Bio-methane for IoT Based Photovoltaic Biogas Hybrid System

Abstract

Biogas is formed when organic biodegradable substances are degraded through bacteria under some anaerobic conditions. Methane is considered as the major substance of biogas but it also includes various number of impurities for instance carbon dioxide (CO2), carbon monoxide (CO), oxygen (O2), hydrogen sulfide (H2S), water (H2O) and dust particles. Transformation is a proper way to remove these contaminates. This conversion offers advantages to improve the quality for a number of anaerobic digestion plants by increasing its life validity. Two technologies are mainly used to get pure Bio-Methane. Cleaning is a primary technique, which has removal of impurities and upgrading process regulates the calorific value of gas. Techniques for raw biogas cleaning are dissimilar in functioning, quality conditions and the efficiency of incoming gas. Upgrading technology is usually performed in the scientific way to achieve the standard value to utilize as fuel for electrification and vehicles. This paper presents a systematical review of major analysis evolution on technologies for conversion of raw biogas to Bio-Methane.
