Dehydration and desulfurization tanks are essential components in modern biogas upgrading systems. Raw biogas—typically produced from anaerobic digestion of agricultural waste, sludge, or organic residues—contains impurities such as moisture, hydrogen sulfide (H₂S), and trace contaminants. These impurities can corrode equipment, reduce calorific value, and create environmental risks.
Our integrated dehydration and desulfurization tank systems are engineered to efficiently remove water vapor and sulfur compounds, delivering clean, dry, and high-quality biogas suitable for power generation, pipeline injection, or upgrading to biomethane. Designed for industrial-scale performance, these systems ensure stable operation across diverse biogas projects including landfills, wastewater treatment plants, and agricultural digesters.
Design Standards
Our systems are designed and manufactured in accordance with internationally recognized standards to ensure safety, reliability, and long service life:
· Pressure Vessel Standards: Compliant with ASME Section VIII or equivalent regional codes
· Material Standards: Stainless steel and carbon steel materials conforming to ASTM International specifications
· Environmental Compliance: Designed to meet emission and safety requirements aligned with ISO environmental management standards (ISO 14001)
· Biogas Processing Guidelines: Engineered in line with European Biogas Association technical recommendations
· Corrosion Protection: Advanced coatings and anti-corrosion treatments for H₂S-rich environments
· Safety Systems: Equipped with pressure relief valves, gas detection interfaces, and explosion-proof instrumentation
Each tank system can be customized based on flow rate, H₂S concentration, humidity levels, and project-specific operational requirements.
