| Abstract | ||
| Proper exploitation of biogas is key to recovering energy from bio waste in the framework of a circular economy and environmental sustainability of the energy sector. This study aimed to design and manufacture an engineering unit for biogas purification. Experiments were carried out through the year of 2021 at Agricultural Engineering Department, Faculty of Agriculture, Damietta University, Egypt. The main parts of the biogas purification system were as follows: Two scrubbers, water pump, compressor and pressure cylinder. The experimental results of desulphurization showed that the highest value of H2S removal efficiency was 95.40% at 500 mm depth of steel wool bed and 6 l/min biogas flow rate. Whereas, the experimental results of purification showed that the lowest CO2 content of 3.54% and the highest CH4 content of 93.86% were found in run (13) at the following conditions: (using desulphurised biogas at 4 bar of pressure, 2 l/min of biogas flow rate and 12 l/min of water flow rate). | ||
