3. Unit biogas purification processes
The issues raised and defined by biogas upgrading require consideration of various interdependent aspects:
the chemical composition of biogas ;
the concentration level of each species ;
the unitary treatment process used ;
application.
These technical difficulties are more easily understood and mastered if they are discretized according to the chemical nature of the compounds, with a view to unitary processing.
The aim of this paragraph is to present the main unit processes that can make up a biogas treatment plant; a concise description of their performance on the target compound(s) is proposed, but mainly their impact on VOCs and siloxanes.
Processes are...
