Laboratory Scale Experiments for Biogas Production using Gas Chromatography Analysis

Abstract

A 2 m 3 floating dome anaerobic digester has been developed and its performance is compared with that of conventional mild steel dome biogas digester The overall objective of carrying the work is anlalyze the efficiency of biogas production for better performance of the digester tank and to optimize the biogas generation under normal operating conditions. The lab scale experiments are carried out in both the digesters in order to determine the composition of biogas and their efficiency. The gas samples which are collected through gas balloons from the biogas plant are taken to the laboratory for determination of composition of biogas by using gas chromatography. The results reviewed that methane composition is increased from 63.40% to 64.22% which holds good as of performance is considered .The greater methane yields results in better performance of the plant and proves to be more effective when compared to that of mild steel dome digester.
