AI Technical Summary
Technical Problem
Existing methods for removing carbon dioxide from biogas in small-scale installations are expensive and unsuitable due to the lack of access to water and electricity, making them impractical for isolated locations.
Method used
An apparatus utilizing liquefaction and solidification of carbon dioxide by cooling the biogas to -60°C and maintaining a pressure above 90 bar, using two heat exchangers and a reservoir to separate carbon dioxide from methane, allowing for efficient CO2 extraction with minimal energy input.
Benefits of technology
The apparatus effectively reduces carbon dioxide to a liquid state for efficient separation from methane, minimizing health risks and maximizing energy yield while requiring only 7.8% of the biogas' potential power for operation.
