Full-Cycle Service Provider
for Biogas Comprehensive Utilization
Chintech Innovation (Shanghai) Technology Development Co., Ltd. — covering seven business segments: investment financing, planning & design, infrastructure & site construction, equipment installation & commissioning, operations, technical services, and R&D.
From financing to commissioning — closed loop within one team
Around biogas purification and biomethane production, we have built full-lifecycle service capabilities. Clients avoid coordinating multiple vendors across project stages, reducing coordination cost and boundary disputes.
Process-wise: front-end wet complexed iron primary desulfurization combined with dry iron oxide fine desulfurization; back-end membrane separation and PSA (Pressure Swing Adsorption) complete purification. Output biomethane achieves CH₄ purity of 95%+, meeting GB/T 41328-2022 national standard, ready for direct pressure-regulated injection into municipal gas pipeline.
Under the National Industry Classification, biogas purification and biomethane production falls under Code 4520 "Biomass Gas Production and Supply" — not chemical industry. Multiple jurisdictions have confirmed such projects are not subject to hazardous chemical safety supervision, streamlining approval and operational processes.

From lab to project
University & Research Partnerships
We maintain long-term collaboration with the Chinese Academy of Sciences, Shanghai Jiao Tong University, Wuhan University of Technology, East China University of Science and Technology and other institutions — R&D results directly applied to engineering practice. For space-constrained projects, we have developed compact purification units achieving 20,000 m³/day capacity within a 200 m² footprint.
