Biogas is produced by fermentation of biological waste products and is considered to be one of the most important renewable energies as replacement of natural gas. Syngas is produced by gasification of a carbon containing fuel and used as intermediate in generating synthetic natural gas. Both gases can contain hydrogen sulphide (H₂S), which needs to be removed to prevent corrosion problems and SOx emissions. Gas desulphurization is therefore essential.
DMT offers a wide portfolio for gas desulphurization: a pure chemical process Sulfurex®CR (Chemical Reaction), a biological process Sulfurex®BF (Biotrickling Filter), and a biochemical process Sulfurex®BR (Biological Regeneration) with integrates a bioreactor for the biological regeneration of the solvent.
