Biogas purification and usage technologies as vehicle fuel

In the study, water scrubbing method, which is the most widely used method in biogas purification process and has the lowest operating cost, was used. Recently, the reuse of treated wastewater has become very important due to the decrease in clean water resources worldwide and the difficulty of utilization. Therefore, treated wastewater was used as biogas scrubbing water in this study instead of clean water. Both the efficiency of wastewater in biogas purification with water washing technique and its effect on the treated wastewater on the parameters of ACM, COD, BOD, pH and conductivity were observed. In the application, long-term washing process was carried out and graphs and tables were created from the data showing the relationship between the absorption efficiency of the washing water and the usage time. In the study, the methane concentration was increased to 90% with a single use of wastewater. The carbon dioxide separation process was carried out successfully.
