Innovative Sustainability at our Core: Leading with BIOPAQ®, ANAMMOX®, and THIOPAQ®

Paques offers a diverse range of products designed to enhance biogas production and wastewater treatment. The BIOPAQ® series, included in more than 1,500 anaerobic reactor installations, generates an amount of biogas that is equivalent to the natural gas needs of 2.8 million Dutch households and reduces CO2 emissions by 11.2 million tons annually, comparable to taking 2,365,000 cars off the road.
ANAMMOX® technology efficiently removes nitrogen from wastewater, while THIOPAQ® specializes in Hydrogen Sulfide (H2S) removal from biogas. This comprehensive product portfolio demonstrates Paques’ innovative approach to sustainable biogas and wastewater management.


Removing Hydrogen Sulfide (H2S) with Paques THIOPAQ®

Hydrogen sulfide (H2S) is a hazardous gas present in biogas, known for its corrosiveness, toxicity, and foul odor. When burned, H2S forms sulfur dioxide (SO2), which is known to contribute to acid rain. Paques’ THIOPAQ® technology provides an effective solution for removing H2S from biogas through a combination of chemical scrubbing, biological oxidation, and physical separation. The result is high-quality biogas and reusable elemental sulfur, offering a cost-effective and environmentally friendly approach to biogas desulfurization.

Paques THIOPAQ® offers exceptional H2S removal efficiency, exceeding 99.5%. The system produces sulfur and a small bleed stream free of sulfides, ensuring safe discharge. Treated biogas can be used in engines, boilers, or local gas grids and upgraded to biomethane for gas networks or vehicle fuel. Elemental sulfur produced can also be used as a high-quality fertilizer.

Developed with academic and industry partners, Paques THIOPAQ® suits various biogas streams and anaerobic systems, handling gas flows from 10 to over 50,000 Nm³/hour and sulfur loads from 10 kg to 50 tons per day.
