RESUMO/ABSTRACT

The transport sector accounts for the second biggest greenhouse gas emission in the European Union (EU). In order to achieve the target of CO2 emission reduction there is a rapid growing interest in using biomethane as fuel for transport applications. Biomethane can be produced through anaerobic digestion or biomass gasification. Anaerobic digestion is a biochemical process. Since the raw gas contains approximately 65vol% CH4 and 35vol%, an upgrading process is needed to remove CO2. Göteborg biomass gasification project (GoBiGas) is the world's first demonstration plant for large-scale production of biomethane through the gasification of forest residues. To achieve high purity CH4, a methanation process is required after gasification. This work compares these two technologies from the perspective of energy efficiency. Simulation results show that they have similar efficiencies: 62-64% for AE and ~65% for GoBiGas.
