Center Enamel Provides Glass-Fused-to-Steel Tanks for Petrochemical Wastewater Treatment Project in Fujian
Center Enamel is delighted to highlight our ongoing collaboration with China National Petroleum Corporation (CNPC) in providing advanced Glass-Fused-to-Steel (GFS) tanks for their complex petrochemical wastewater treatment requirements. This partnership underscores Center Enamel's technical capacity to deliver durable, large-scale, and chemically resistant storage solutions tailored to the strict safety and environmental standards of the petrochemical industry.
Project Overview and Technical Specifications
In a significant step toward optimizing wastewater management in the petrochemical sector, Center Enamel supplied and installed four high-capacity GFS tanks for CNPC’s facility in Fujian, China, completed in June 2019. Petrochemical effluent is characterized by high concentrations of hydrocarbons, toxic solvents, and aggressive chemical compounds that severely damage conventional steel or concrete structures. To handle these complexities, the project incorporates four heavy-duty GFS tanks featuring integrated Glass-Fused-to-Steel (GFS) roofs.
● Tank 1: 13.75m x 20.4m (3027m3 capacity) – 1 set
● Tank 2: 13.75m x 21.6m (3205m3 capacity) – 1 set
● Tank 3: 19.11m x 20.4m (5848m3 capacity) – 2 sets
● Installation Date: June 2019
Advanced Engineering for Petrochemical Effluent Containment
Petrochemical wastewater treatment plants demand exceptional material performance to prevent environmental leaks and structural degradation. Center Enamel's GFS technology provides distinct operational benefits:
● Thermal Fusion Coating Durability: Porcelain enamel glass is fused to high-strength structural steel at extreme temperatures (820°C to 930°C), creating an impenetrable molecular barrier that withstands aggressive chemical immersion and oxidation.
● Hermetically Sealed GFS Roofs: The matching glass-fused-to-steel roofs ensure complete vapor containment, preventing hazardous volatile organic compound (VOC) emissions and protecting internal contents from atmospheric contamination.
● Rapid Modular Bolted Construction: Prefabricated bolted panels allow efficient transport and rapid assembly on-site, minimizing construction footprints in heavy industrial zones.
Comparative Matrix: Petrochemical Wastewater Storage Technologies
Evaluation Parameter | Center Enamel Glass-Fused-to-Steel (GFS) Tanks | Cast-in-Place Concrete Basins | Conventional Welded Carbon Steel Tanks |
Chemical & Hydrocarbon Resistance | Permanent glass-steel fusion completely resists organic solvents, oils, and aggressive chemicals | Vulnerable to concrete carbonation, chemical etching, and subsurface seepage | High susceptibility to interior pitting, corrosion, and coating failure |
Vapor & Emission Control | Equipped with gas-tight GFS roofs for secure VOC containment and odor suppression | Requires complex, costly separate concrete slab covers or synthetic liners | Requires external structural frame covers susceptible to vapor corrosion |
Installation Speed & Rigging | Rapid modular bolted erection completed efficiently in industrial settings | Extremely slow civil construction requiring formwork, pouring, and long curing cycles | Slow field construction requiring extensive manual welding and field coating |
Frequently Asked Questions (FAQ)
Q: What is the scope of Center Enamel's collaboration with CNPC in Fujian?
A: Center Enamel supplied and installed four large Glass-Fused-to-Steel (GFS) tanks with matching GFS roofs for CNPC's petrochemical wastewater treatment project in Fujian, China, completed in June 2019.
Q: What are the exact dimensions and capacities of the tanks supplied for this project?
A: The project features four tanks across three distinct size configurations: Tank 1 (13.75m x 20.4m, 3027m3), Tank 2 (13.75m x 21.6m, 3205m3), and two units of Tank 3 (19.11m x 20.4m, 5848m3 each).
Q: Why are Glass-Fused-to-Steel (GFS) tanks ideal for petrochemical wastewater?
A: Petrochemical effluent contains aggressive solvents and hydrocarbons. GFS tanks combine high-strength steel with an inert, non-porous glass lining fused at high temperatures, offering superior resistance to chemical corrosion and structural breakdown.
Q: What type of roofs were installed on these petrochemical tanks?
A: The tanks are equipped with specialized Glass-Fused-to-Steel (GFS) roofs, providing a hermetically sealed, corrosion-resistant overhead structure that ensures excellent vapor containment and environmental safety.
