Technical Parameters
Carbon Petroleum Coke Silos
Spiral-welded carbon petroleum coke silos feature a sealed structure crafted through spiral-welded edge technology. Precisely addressing storage challenges such as petroleum coke's spontaneous combustion, dust dispersion, and moisture-induced caking, these silos are widely used in petrochemical, metallurgical, and carbon industries.
Core Structural Design
The cylindrical silo body is manufactured from premium galvanized steel or carbon steel, formed through spiral rolling and interlocking by specialized machinery. This process significantly enhances overall strength and load-bearing capacity. Sizes are customizable, with individual silo capacities ranging from thousands to tens of thousands of tons to accommodate diverse storage requirements.
The silo base is typically designed with a conical structure to minimize dead zones in petroleum coke accumulation, ensuring smooth discharge. When integrated with ventilation ducts, it facilitates uniform airflow throughout the silo.
Silo walls often feature dual-layer protection: the inner layer is coated with wear-resistant and anti-corrosive material to withstand mild corrosion from petroleum coke, while the outer layer combines galvanization with anti-corrosive spray paint to extend outdoor service life.
Core Performance Advantages
● High Safety Adaptability: Spiral-welded construction achieves seamless sealing, effectively isolating moisture and air. This reduces the likelihood of petroleum coke clumping due to dampness and significantly minimizes spontaneous combustion risks from oxygen exposure, ensuring stable quality of carbon petroleum coke during storage.
● Outstanding Economy and Environmental Performance: Modular roll-forming construction eliminates complex scaffolding, drastically shortening the construction cycle. Post-installation maintenance is minimal, requiring only periodic inspections of the anti-corrosion coating and regular checks of dust removal and ventilation equipment. Furthermore, the sealed design and dust collection system minimize dust dispersion, aligning with stringent environmental policies and supporting enterprises in achieving green storage.
● High Space Utilization: Featuring large single-bin capacity and compact structure, multiple bins can be arranged side-by-side with a minimum inter-bin spacing of just 500 mm. This maximizes land utilization within industrial sites, freeing up space for other production facilities.
Primary Applications
Petrochemical Industry
Serves as supporting infrastructure for refineries, storing petroleum coke byproducts generated during crude oil refining for subsequent transportation or further processing.
Metallurgy and Carbon Industry
Stores petroleum coke used as smelting additives or raw materials for carbon products, such as providing stable feedstock for prebaked anode production in the electrolytic aluminum sector to ensure continuous production processes.
Transit Storage
Deployed at ports or bulk commodity hubs for temporary storage during petroleum coke import/export and cross-regional transshipment. Compatible with conveyor belts and loading equipment to enable rapid loading/unloading and turnover.
