Zinc Oxide Desulfurizer — H₂S removal

Description

Product Overview
This high-performance Zinc Oxide Desulfurizer is engineered for the precise removal of hydrogen sulfide (H₂S) from industrial gas streams, including natural gas, biogas, synthesis gas, and refinery off-gases. Its primary value lies in delivering H₂S reduction to sub-ppm levels, protecting downstream catalysts and equipment from corrosion and poisoning. With superior sulfur absorption capacity and low pressure drop, it offers a strategically critical balance of operational efficiency and cost-effectiveness for global energy and chemical producers.

Key Specifications & Technical Characteristics

• Chemical composition: ZnO (zinc oxide) ≥ 95%, with proprietary promoters

• Purity: Industrial grade, free of heavy metal contaminants

• Physical form: Extruded pellets (4×5–10 mm) or spherical beads; white to light yellow

• Bulk density: 0.8–1.1 g/cm³

• Surface area: 50–80 m²/g; crush strength ≥ 50 N/cm

• Packaging options: 25 kg laminated paper bags, 500 kg FIBCs, or 1000 kg big bags

• Shelf life: 24 months in unopened, dry, sealed packaging

Core Industrial Applications

• Oil & gas: Upstream natural gas sweetening; H₂S removal from LPG and condensate stabilizer off-gas

• Biogas & landfills: Polishing to meet natural gas grid injection or vehicle fuel standards (<4 ppm H₂S)

• Syngas & hydrogen plants: Guard bed service before methanol synthesis, Fischer-Tropsch, or fuel cells

• Refining: Claus tail gas cleanup and amine unit protection

• Performance edge: Higher breakthrough sulfur capacity (25–35 wt%) than iron oxide or activated carbon, with no leachate disposal issues.

Competitive Advantages

• Quality consistency: ISO 9001:2025 certified; each batch tested for H₂S adsorption capacity (ASTM D664 method)

• Supply reliability: Dedicated production lines with 15,000 MT annual capacity; safety stock held in three regional hubs

• Logistics capability: Just-in-time delivery to any major port within 21 days

• Price competitiveness: Direct mine-to-manufacturer zinc sourcing eliminates raw material volatility premiums
