The biogas cryogenic dryer supplied as part of this project serves as a core auxiliary unit in the VOCs treatment system for wastewater from the coal-to-liquids plant. The equipment is designed to perform deep dehydration and purification of biogas generated by the IC anaerobic reactor, effectively removing moisture and impurities. The treated clean biogas can then be directly fed into the incinerator for combustion and utilization, seamlessly completing the closed-loop process for the resource‑recovery and harmless treatment of biogas in the coal‑chemical industry.

The Ili region of Xinjiang, with its high altitude, large diurnal temperature range, and complex climatic conditions, places extremely stringent demands on the weather resistance, stability, and safety of industrial equipment.

Integrated skid-mounted design: Compact in design, easy to install, and simple to operate and maintain, it is well-suited to the tight layouts of industrial sites, significantly reducing on-site construction costs and timelines.

Water-cooled explosion-proof configuration: Strictly adheres to explosion-proof standards for the petrochemical industry, is compatible with high-risk production environments in the coal chemical sector, and eliminates potential safety hazards.

Corrosion-resistant and durable material: All gas‑flow components of the equipment are fabricated from 304 stainless steel, offering resistance to biogas corrosion and fouling, thereby significantly extending the equipment’s service life.
