Ruichang International has successfully completed and handed over the waste gas and waste liquid incineration system for Shaanxi Xingsheng Green Energy New Material Co., Ltd.’s “CO₂–Ethylene Coupled Carbonylation Integrated Project (Phase I).” After finishing commissioning and achieving a smooth first trial run, the system officially entered stable operation earlier this month.
Located in the Yushen Industrial Park in Yulin City, Shaanxi Province, the Xingsheng Green Energy project is the world’s first industrial unit to realize carbonylation reactions using carbon dioxide as a raw material. The facility plays a pioneering role in advancing China’s “dual-carbon” goals and driving high-value transformation within the olefin industry. By adopting an innovative reaction pathway that converts CO₂ into valuable chemical intermediates, the project marks a significant step forward for low-carbon technologies and circular chemical production.
A High-Performance Incineration System Engineered for Green Production
As the EPC contractor for the project’s waste gas and waste liquid incineration system, Ruichang International delivered the full process—from engineering design and equipment manufacturing to installation, commissioning, and start-up—under a demanding schedule and complex process requirements. The system’s performance highlights four core technical advantages:
- Industry-Leading Destruction Efficiency
The system integrates advanced staged combustion with high-temperature cracking technology, achieving a destruction and removal efficiency (DRE) of over 99.8%, significantly reducing downstream residue treatment needs.
- Outstanding Environmental Compliance
A multi-stage flue gas purification train combining acid gas removal and baghouse filtration ensures that all emissions remain well below China’s latest national standards. The process achieves true harmlessness and reduction, aligning with the project’s stringent environmental targets.
- Long-Term Operational Stability
Built with specialty alloy materials and equipped with intelligent temperature control and automated safety-warning functions, the unit maintains a continuous stable operating rate of over 98%, ensuring reliability for uninterrupted plant production.
- Significant Energy Savings
An integrated waste heat recovery system converts high-grade thermal energy into steam or hot water for plant-wide use. This configuration reduces external energy consumption by approximately 30% annually, delivering both environmental and economic benefits.
Recognized as an “Outstanding Supplier”
In recognition of the excellence demonstrated throughout project execution, Ruichang International was honored with the title of “Outstanding Supplier” in Shaanxi Xingsheng Green Energy’s annual supplier evaluation. This award reflects the client’s high regard for Ruichang’s engineering quality, service capability, and professional execution.
Expanding Capabilities Across the Energy and Petrochemical Sectors
The successful delivery of this landmark system also highlights the broader technical ecosystem of Ruichang International. As a leading energy-efficient and environmental engineering company listed in Hong Kong, Ruichang specializes in industrial combustion systems, waste heat recovery, CO₂ and sulfur-based pollutant treatment, sulfur recovery unit(Claus and TGTU units), waste gas and waste liquid incineration, flue gas plume control, and modular EPC solutions for petrochemical, natural gas processing, fine chemical, coal chemical, and new-materials industries.
Through its subsidiaries Ruichang Environmental Engineering (Luoyang) and Recher Petrochemical Engineering (Shanghai), the company integrates R&D, core equipment manufacturing, engineering design, EPC execution, and modular plant delivery, enabling it to provide global customers with safe, efficient, and environmentally responsible system solutions.
A Milestone for Sustainable Industrial Development
The completion of the CO₂–ethylene coupled carbonylation project represents another important achievement in Ruichang International’s efforts to support cleaner production and low-carbon transformation across the petrochemical industry. Moving forward, the company will continue to strengthen innovation in combustion, thermal energy, catalytic processing, and environmental technologies, while promoting modular, high-efficiency, and green engineering solutions worldwide.
