Hello everyone and thank you for reading.
For a student research project, I need data/information concerning the environmental impacts of sulphur and CO2 removal technologies used in biogas plants. The technologies analyzed in our paper are absorption in water, chemical absorption using NaOH/FeCl3/Fe(OH)3, adsorption with activated carbon, membranes and biotechnological approaches (oxygen dosing, biotrickling filter, bioscrubber).
As this description is very broad and our paper should just give an overview, I would be very thankful for any sources.
