ZHGAS (Chinese Academy of Sciences Hefei Gasification Technology Co., Ltd.), a national high-tech enterprise under the CAS Institute of Engineering Thermophysics (IET), originated from the Power Research Laboratory established by Dr. Wu Zhonghua in 1956. Today, IET stands as a leading strategic institute in "Power & Electrical Engineering" and "Energy Science & Technology." ZHGAS holds Class B Design and EPC Qualification for the chemical, petrochemical, and pharmaceutical industries. Leveraging 110+ core patents in CGAS (Circulating Fluidized Bed Gasification) technology, the company has delivered 40+ large-scale CGAS coal-to-gas projects, specializing in R&D, technology transfer, equipment supply, EPC turnkey contracts, and operations for clean industrial gas/syngas production from coal and biomass. Aligned with CAS’s mission of "Four Pioneering Goals" and "Three-Oriented Development," ZHGAS was selected for the 2017 CAS Hongguang Initiative (one of 10 projects nationwide) and awarded the CAS Science & Technology Promotion Prize.
The company employs over 80 R&D and engineering design personnel, including 7 Professor-level Senior Engineers, 9 Senior Engineers, and 40+ doctoral/master’s graduates, covering product development, project management, and specialized fields such as process engineering, equipment design, piping systems, electrical engineering, and instrumentation. A rigorous design management system certified by China Quality Certification Centre’s ISO 9001 standards is strictly implemented, enforcing a designer-checker-reviewer system, unified design templates, optimized workflows, and enhanced precision through 3D modeling software.
Driven by innovation, the company has invested over RMB 30 million in R&D over three years through national/provincial projects (e.g., National R&D Program, Hongguang Initiative), focusing on technologies including ash melting for gasifiers, slagging prevention, gasifier operational diagnostics, and energy-saving solutions. These innovations deliver 1-2% efficiency gains, **>50,000-ton annual coal reduction**, and RMB 20 million+ cost savings for clients.
Services include feasibility studies, energy efficiency diagnostics, preliminary/detailed engineering design, automation control schemes, HAZOP studies, occupational disease/fire protection compliance designs, and safety implementation plans. Beyond standardized products, tailored solutions are developed based on client-specified coal gas applications (e.g., industrial fuel/chemical feedstock), coal grades, and steam/gas pressure parameters, serving industries like alumina, magnesium metal, nickel-iron, steel rolling, glass, ceramics, lime kilns, and syngas for ammonia/methanol production.
In addition to conventional EPC (Engineering-Procurement-Construction) and after-sales support, the company provides lifecycle upgrade services:
① Expert diagnostics & optimization: Remote monitoring + operational parameter adjustments to enhance gasifier performance;
② Coal adaptation: Dynamic parameter optimization for variable coal grades;
③ Technical retrofits: Low-cost, high-efficiency upgrade solutions from design to construction.
The company possesses proprietary Oxy-enriched Circulating Fluidized Bed (CFB) Gasification Technology with the following advantages:
Extensive Coal Adaptability: Suitable for low-rank coals (e.g., lignite, long-flame coal), "three-high" inferior coals (high-ash, high-ash-melting-point, high-sulfur), and low-reactivity coals (e.g., anthracite, lean coal), resolving challenges in coal selection, high procurement costs, and unstable supply
.
Flexible Gasification & Product Solutions: Through oxy-enriched air or pure oxygen gasification, it directly produces high-calorific fuel gas and chemical synthesis gas continuously and stably, eliminating the need for natural gas blending or gas separation to adjust composition
.
Serialized Gasifier Specifications: Covers industrial fuel gas and chemical feedstock gas production, with single-unit capacity of 10,000–100,000 Nm³/h. Also provides 5,000–50,000 Nm³/h gasifiers for biomass/sludge/waste gasification coupled with power generation
.
Integrated Design-Construction-Operation: Rapidly translates technical solutions into execution, reducing project cycles to 5–6 months for design, procurement, construction, and commissioning
.
Sustained Innovation & Upgrades: Offers full-lifecycle technical retrofits to help clients meet evolving energy-saving and environmental standards while enhancing product competitiveness
Advanced incineration technology processes hazardous waste gases/liquids from upstream chemical units, achieving **>99.99% destruction efficiency and compliance with national/EU emission standards (e.g., NOx < 50mg/Nm³). Systems prioritize operational safety, low maintenance, and compact footprint. High-temperature flue gas recovers steam via waste heat boilers, with thermal efficiency exceeding 85%**
