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.
Scrubber for removing H₂S from biogas. The system oxidises H₂S into elemental sulphur and sulphates. The scrubber includes PP vessels, circulation pumps, air blowers, nutrient dosing and automatic control. It achieves 96% H₂S removal, reducing the concentration from 2,500 ppm to 100 ppm
Biological scrubber for H₂S removal from biogas. The system uses microorganisms to oxidise hydrogen sulphide into elemental sulphur and sulphates. The scrubber includes a PP tank, filter media, circulation pumps, process air blower, nutrient dosing system, instrumentation and automatic process control. Designed for a biogas flow rate of 1,100 m³/h, the system achieves an H₂S removal efficiency of 94%, reducing the H₂S concentration from 2,500 ppm to ≤150 ppm.
