Sulphur removal
Scrubbers and activated carbon adsorption columns for hydrogen sulfide (H₂S) removal from biogas. The equipment is individually sized for biogas flow rates from 50 to 10,000 m³/h and inlet H₂S concentrations from 1,500 to 5,000 ppm. Scrubbers provide bulk H₂S removal, reducing concentrations to 50–100 ppm. Activated carbon columns are used for fine final polishing, reducing H₂S concentration to 0 ppm.
