Your challenges
Presence of H2S in biogas
H2S is a component in biogas that requires treatment, before the biogas can be utilized as an energy source. Econvert-RTF® achieves a 99% H2S removal rate, and allows the biogas to be re-used directly or with additional polishing with activated carbon filters depending on end-user needs.
Sustainability and carbon footprint goals
There is pressure for companies to become more sustainable and to achieve certain sustainability goals. Econvert-RTF® ensures that energy recovered is not only renewable but also enables to burn the biogas in a correct way without harmful sulfur emissions.
Rising energy costs
Energy costs are continuously increasing, and there is pressure to adopt renewable energy. Econvert-RTF® treats biogas and ensures the biogas has the right quality, pressure and humidity for re-use. The reliable performance and non-clogging set-up enables a high uptime and high energy recovery availability.
Want to know how our innovative wastewater treatment and biogas desulfurization solutions can benefit your business?
The process
The Econvert-RTF® is a regenerative trickling filter designed for biogas desulfurization. It consists of a filter bed in which hydrogen sulfide is removed from the biogas through biological oxidation. Depending on the selected process conditions, the system can be steered towards either elemental sulfur or sulfuric acid production. The key innovation of Econvert-RTF® is its ability to regenerate (i.e. ‘wash’) the filter bed material. Regular decommissioning of the desulfurization installation to clean the filter bed is no longer necessary, since solids accumulation is prevented by automatic recirculation of the filter bed material. Aerobic effluent can be reused as suppletion water (if available), minimizing (potable) water consumption.
Our positive impact
The reliable biological solution without chemicals
>99% H2S removal efficiency
H2S removal rates of over 99% can be achieved. Due to the high H2S removal rates, the biogas can be reused directly or only needs minor additional polishing with activated carbon filters depending on end-user requirements.
Low operational costs
Due to the regeneration of the alkalinity in the bioreactor the operational costs are low. Compared to chemical systems where no alkalinity is regenerated, the amount of caustic consumption can be up to 20 times less.
No clogging
Clogging in the Econvert-RTF® is prevented by its built-in cleaning system. During operation the installation can be put in cleaning mode without any negative effects on the ongoing biogas treatment.
Continuous operation
Econvert-RTF® can be operated continuously, without regular time-consuming and extensive maintenance work.
