Petroleum Coke Silo System

Product overview

This petroleum coke silo system automates and stabilizes the full material path—from enclosed storage to accurate batching and controlled conveying—so petroleum coke can be delivered to downstream processes with repeatable ratios, fewer operator touches, and lower dust loss. Designed for petroleum coke storage and controlled discharge where dust containment and abrasion exposure are system-defining factors, the system typically combines a galvanized spiral steel silo, sealed transfer interfaces, and an intelligent batching platform to improve production continuity while reducing human error and unnecessary energy consumption.

Specifications: 100–20,000 m³ (Diameter: 3 m–35 m)

Key control focus: enclosed handling, dust capture, abrasion management, discharge stability. Tight sealing helps prevent moisture ingress, oxidation risks, and dust overflow at storage and transfer points. Discharge stability is commonly protected by conical or flat-bottom configurations with arch-breaking/vibration or fluidizing aids to reduce compaction and bridging. Where petroleum coke is treated as flammable in the project safety plan, typical scope boundaries include ventilation, explosion protection elements, and temperature monitoring to keep storage and discharge safer during continuous operation.

Typical equipment package: steel silo + silo dust collector + conveying (belt conveyor / bucket elevator) + discharge aids + packaging/loading interface.

This grain silo system is specified for wheat/corn/rice and similar bulk grains where airtight preservation, pest control, and data-driven condition management are part of the procurement acceptance boundary—not only capacity. It is typically selected to reduce mildew/insect loss and keep intake/outfeed stable with mechanized handling and closed storage.

Engineering envelope (typical)

Product specifications: 100–20,000 m³ (φ3 m–φ35 m) (site-dependent configuration)

Preservation basis (what usually gets checked)

Airtight sealing and fumigation capability are commonly defined by airtightness ≤ 500 Pa and pressure half-life ≥ 5 min, with sealed interfaces that support fumigation/insecticide control (e.g., phosphine concentration ≥ 200 ppm where specified).

Temperature & quality stability

Ventilation + circulation control is commonly reviewed to limit internal temperature stratification (e.g., temperature difference ≤ 2°C), supported by distributed sensing (e.g., 1 temperature/humidity point per 100 m²) and early warning signals such as CO₂ monitoring for mold risk.

Discharge & handling continuity

Discharge stability is commonly anchored on cone bottom angle ≥ 45° plus a vibrating discharge device, with low residue targets (e.g., residue < 0.1%) to support turnover without repeated manual clean-out.

Typical equipment package

Grain steel silo + sealing system + ventilation/fumigation interfaces + monitoring (T/RH/CO₂) + discharge aids + conveying interfaces (bucket elevator / belt conveyor) + sampling/automation options (as ordered).

Mining Silo System

Product overview

Applied to mining bulk materials and mineral powders where abrasion, high-duty transfer, and sealed dust control define the purchase scope—especially for continuous loading, short dispatch windows, and strict housekeeping requirements.

Product specifications (typical)
Capacity: 100–20,000 m³ · Diameter: φ3–φ35 m

Key control focus

• Dust containment & compliance: fully enclosed structure with sealed feed/discharge points; roof bag dust collection + negative-pressure exhaust (capture targets commonly stated up to 99%, emission ≤15 mg/m³ where specified).

• Abrasion exposure & uptime: wear-resistant silo wall / liners and multi-stage arch-breaking to keep discharge stable under harsh material behavior.

• Moisture stability & stock quality: enclosed storage reduces weather impact; moisture fluctuation targets can be defined (e.g., ±0.5% where specified).

• Digital inventory & loss control: 3D level measurement + algorithm logic to keep inventory deviation <0.5% and trigger abnormal-loss alarms.

• O&M readiness: real-time stress/deformation monitoring (warning accuracy ±2 mm), remote control, and mobile visualization.

• Closed-loop site management: sealed drainage + sedimentation recycling for dust suppression to support “zero discharge” site objectives where required.

Typical equipment package
Steel silo + sealed feed/discharge + belt conveyor / bucket elevator + bag dust collector + negative-pressure exhaust + discharge aids (anti-arching) + level/condition monitoring + loading/packaging interface (as ordered).

Materials and corrosion protection option

This entry supports scope language that may include stainless steel silo and galvanized steel silo alongside standard steel silo structures, depending on environment and project definition.

• Steel silo: used broadly across powder and granule storage where structural design, discharge control, and system integration define performance.
• Stainless steel silo: commonly written where corrosion resistance, cleanliness, or specific process requirements are part of the acceptance boundary.
• Galvanized steel silo: commonly written where atmospheric corrosion control is prioritized and long-term exterior protection is part of the deliverable.
• Insulated steel silo: selected where temperature swing, condensation control, or material stability drives insulation requirements.

Quality, compliance, and acceptance package

Project-Ready Supply: What Octal Controls Beyond the Steel Silo Structure

Octal positions its China steel silo scope as an acceptance-ready supply package, not just fabricated steel. Steel silo structures, silo system modules, and related liquid tanks can be released under one boundary with interface lists that match how EPC and plant teams review equipment. Each shipment is organized so receiving can be closed by item and lot: packing lists map to equipment IDs, and marking/protection is applied for key interfaces to reduce site damage and “missing identity” NCRs. For system packages, Octal aligns transfer and dust-control equipment (dust collector, conveying/lifting, discharge/pneumatic interfaces, valves, and packaging/export modules) to the defined throughput and material behavior so the silo does not become a standalone bottleneck. Configuration is built around project inputs—capacity, diameter, material flow-ability/abrasion, enclosure and dust targets (including fly ash compliance cases), automation scope, and packaging mode—so the delivered scope matches the specification rather than requiring rework after arrival. After delivery, Octal supports spare parts and interface troubleshooting to keep commissioning and ongoing operation stable.
