THIOPAQ® is a cost-effective and sustainable biogas purification system with which you can meet stringent gas quality requirements. The THIOPAQ® was invented and developed by Paques, in cooperation with universities. It has become the go-to technology for biological H2S removal, and is commonly applied in the wastewater treatment, biomethane and oil & gas industries.
What makes THIOPAQ® unique
Broad applicability of THIOPAQ®
Almost any gas-containing H2S can be purified by the THIOPAQ® gas purification system, including biogas, syngas, CO2-rich (off)-gasses, vent streams, and geothermal gas. The THIOPAQ® can be combined with any anaerobic wastewater treatment or digestion system. Applications for the biogas upgrading system extend across the pulp & paper, food & beverage, wastewater treatment, landfill, municipal, bioethanol, sludge/solids digestion, and biofuels industries.
Biogas flows vary from 50 Nm3/hour to more than 50,000 Nm3/hour, and daily sulfur loads range from 10 kg/day to 50,000 kg/day. Standardized systems such as this biogas purification system enable short project lead-times, while Paques’ experienced engineering team can tailor the unit to meet your specific needs.
The THIOPAQ® process explained
The THIOPAQ® (bio)gas filtration system combines fast chemical absorption to remove H2S from (bio)gas and a robust biological recovery of sulfur. It consists of an absorber column coupled to a biological reactor and sulfur recovery device.
In the absorber, H2S -containing gas is brought in contact with washing water via countercurrent exchange, where H2S readily dissolves into the slightly alkaline wash water.
In the bioreactor, naturally-occurring bacteria oxidize the sulfide to elemental sulfur particles, simultaneously regenerating the washing solution. This allows the alkaline washing solution to be continuously reused in the absorber column, leading to very low operational costs.
The sulfur produced in the system is separated in a solids separation step, and can be reused as a high-quality, organic fertilizer.
