Gas desulfurization

Essential for biogas upgrading

One of the most important renewable energies

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 desulfurization is therefore essential.

DMT’s Sulfurex®

We offering several options for gas desulfurization: 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.

Sulfurex®BR

Sulfurex®BR is a flexible desulfurization technology that achieves low hydrogen sulfide outlet concentrations with low operational expenses thanks to the regeneration step.

Sulfurex®BF

Sulfurex®BF technology is a simple way of desulfurization without the use of chemicals. The system operates as a biotrickling filter.

Sulfurex®CR

The Sulfurex®CR technology operates as a counter-current scrubber to ensure the intense contact between (bio)gas and caustic solution in order to reach maximum removal efficiency.

What is desulfurization process?

It is the process of using hydrogen gas to reduce the sulfur content in hydrocarbons thus reducing the emissions of sulfur oxides which are responsible for acid rain.
