Hydrogen Sulphide Removal

ERG has been treating H₂S in polluted gas streams for more than 40 years. We have broad experience in most sectors of the waste and chemical industries, and many more besides. We can offer a system which includes a packed tower scrubber using an alkaline scrubbing liquor, or for waste or waste water industry odour control we provide biological scrubbing and carbon filtration.

Search our case studies and contact our sales team for further information or a quotation for your application.

Applications where we have experience include:

Sulphonated acid-gas scrubbing from LEV extraction and process reactors in the pharmaceutical, agrochemical and fine chemicals industries. Either packed towers or V-tex® scrubbers, and frequently supplied by ERG as skid-mounted packages.
H₂S capture from biogas generated in anaerobic digestion processes – either municipal waste or sewage sludge digestion in the waste water industry. H₂S removal is part of the gas sweetening process to improve the operation of downstream compressors or gas engines, and to limit the SO₂ content of the eventual flue gas.
Scrubbing H₂S as part of syngas treatment in renewable energy generation.
Odour control packages for waste water treatment in many industry sectors. These could be large-scale treatment plants in the waste water industries, local ETPs on chemical, pharmaceutical, automotive, etc manufacturing sites, or even for smaller local ETPs in residential or tourist resorts.
