Iron Oxide Pellet — Sulfur scavenging

Description

1. Product Overview (expanded per prompt)

This product is a dense, spherical iron oxide pellet engineered for high-efficiency H₂S removal in dry or wet gas streams. It is used primarily in upstream oil & gas, biogas plants, and petrochemical pre‑treatment to achieve sub‑ppm sulfur levels. The value proposition lies in its high breakthrough capacity (up to 40% wt sulfur loading) and non-caking, dust-free handling. Strategically, it reduces replacement frequency and hazardous waste volumes, making it critical for operators aiming to lower carbon footprint and operational downtime.

2. Key Specifications & Technical Characteristics

• Chemical composition: Fe₂O₃ · H₂O (granulated hematite/goethite blend), ≥ 88% active iron oxide

• Purity level: > 95% iron oxide content; < 0.5% soluble salts; H₂S removal efficiency ≥ 99.8%

• Physical characteristics:

  • Form: Spherical pellets

  • Color: Reddish brown to dark brown

  • Particle size: 2–5 mm (standard), 1–3 mm available

  • Bulk density: 1.2–1.4 g/cm³

  • Crush strength: ≥ 15 kg/pellet

  • Surface area: > 50 m²/g

• Packaging options: 1 MT super sacks (FIBC), 25 kg laminated bags, or bulk pneumatic trailers

• Shelf life: 24 months in dry, sealed packaging; store away from acids and moisture

3. Core Industrial Applications

• Natural gas processing (upstream / midstream) – Removes H₂S from 5,000 ppm down to < 4 ppm for pipeline compliance. Outperforms iron sponge by higher porosity and lower bed shrinkage.

• Biogas upgrading to biomethane – Polishes biogas from digesters or landfills; operates at high humidity with no deactivation, reducing replacement frequency by 30% vs. granular oxide.

• Refinery fuel gas and amine guard beds – Protects downstream catalysts and compressors from sulfur poisoning; lower pressure drop (ΔP < 0.2 bar per meter) cuts energy costs.

• Landfill gas treatment – Performs at variable flow rates and H₂S spikes (up to 10,000 ppm) without thermal runaway, unlike liquid scavengers.

4. Competitive Advantages

• Quality consistency – Lot-to-lot uniformity with full traceability; independent SGS/Intertek analysis available per shipment.

• Supply reliability – 100+ MT monthly production capacity; safety stock held in three regional hubs (Americas, Europe, Middle East).

• Logistics capability – Global shipping with incoterms EXW, FOB, CIF; lead times 7–14 days from order.

• Price competitiveness – 15–20% lower cost per kg of sulfur removed vs. iron sponge or iron chelate liquids; no expensive disposal surcharges.

• Sustainability – Spent pellets are non-hazardous (EPA TCLP compliant) and can be used as iron feedstock in cement or steel industry.

• Technical support – Free bed design calculation, breakthrough modeling, and on-site sampling kits included for contract volumes.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ) – 20 MT (bulk order)

• Loading capacity – 22 MT per 20‑ft standard container (stuffed with 1 MT super sacks)
