Absorption Technologies for Biomethane Production from Biogas to Replace Natural Gas in Gas Distribution Networks and Use as Motor Fuel

Modern eco-friendly oriented countries are implementing biomethane from biogas production projects, using biomethane as motor fuel or supplying it to the natural gas distribution grid. It is also extremely relevant for Ukraine, supposing the problems with gas import due to Russian aggression. Biogas production from landfills, agriculture waste, and sewage was successfully implemented in Ukraine with electricity production. The next step is biogas processing into biomethane (natural gas substitution) and carbon dioxide (commercial product). The most applicable technologies for Ukraine were selected: amine, water, and combined water-amine carbon dioxide separation. These technologies had compared using computer simulation with real landfill biogas flow rate and chemical content. The are combined water-amine separation technology was selected and explored in more details with the laboratory unit.
