About the project
The use of upgraded biogas as vehicle fuel is considered as one of the most efficient means of utilizing renewable energy to reduce greenhouse-gas emissions from the transportation sector. Biogas upgrading using current technologies is energy-intensive (consumes up to 30% of the energy of the gas).
Ionic liquid (IL, a liquid CO2 absorption solvent) has been proposed as a promising absorbent for biogas upgrading with lower energy consumption. Extensive research work has been conducted since 2001. However, there is a need for further techno-economic analysis. In this project, the IL performance for biogas upgrading will be evaluated and techno-economic analysis will be conducted.
During the course of the project, Yujiao Xie at Luleå University of Technology, Department of Engineering Sciences and Mathematics, finished her Doctoral Thesis with the title CO2 separation with ionic liquids – from properties to process simulation. Some parts of the thesis were carried out in connection to the project.
