Sodium Hydrosulfide Bulk — Gas treatment

Description

Product Overview
Sodium Hydrosulfide Bulk (NaHS) is a high-purity, industrial-grade reagent engineered for efficient sour gas treatment, specifically the scavenging of hydrogen sulfide (H₂S) from refinery, petrochemical, and natural gas streams. Its key value proposition is delivering rapid, stoichiometric H₂S neutralization while minimizing downstream sludge formation and operational downtime. Strategically, this product is indispensable as global sulfur emission regulations tighten, making reliable NaHS supply a critical lever for compliance and cost management in hydrocarbon processing.

Key Specifications & Technical Characteristics

• Chemical composition: Sodium Hydrosulfide (NaHS), typically 32–48% aqueous solution or flake form; low iron and low sodium carbonate content

• Purity grade: Technical grade ≥32% (liquid) / ≥70% (flake) with <0.5% Na₂S impurity

• Physical characteristics: Clear yellow to light green liquid (solution); off-white to yellow crystalline flake; density 1.18–1.32 g/cm³ at 20°C

• Packaging options: ISO tank (20–24 MT), IBC totes (1,200 kg), steel drums (200 kg net), or bulk tanker

• Shelf life: 6 months (solution) / 12 months (flake) when stored in sealed, nitrogen-blanketed containers away from moisture and acids

Core Industrial Applications

• Oil & gas refining: Direct injection into amine units and caustic wash systems to convert residual H₂S into sodium sulfide, reducing corrosion and toxic emissions.

• Pulp & paper (Kraft process) : Selective sulfide generation for pulping liquor; outperforms elemental sulfur in reaction speed and yield consistency.

• Mining (copper/molybdenum flotation) : Depressant for iron sulfides; provides better selectivity and lower dosage than cyanide alternatives.

• Leather & tannery: Unhairing agent where controlled sulfur release improves hide quality and reduces effluent BOD/COD by 20–30% versus lime-sulfide blends.

Competitive Advantages

• Quality consistency: Batch-to-batch <±1% active content variation with third-party SGS/Intertek certification.

• Supply reliability: Dedicated export terminals in Houston, Rotterdam, and Singapore enabling 7-day lead times for 20 KT+ monthly volumes.

• Cost advantage: Byproduct sourcing from leading mercaptan units yields 12–15% lower pricing than virgin-synthesis competitors.

• Sustainability: Closed-loop returnable ISO tank program reduces single-use drum waste by 90% for qualified partners.

• Technical support: On-staff chemical engineers provide free dosage modeling and emergency H₂S safety audits.

Commercial & Supply Information

• Minimum order quantity (MOQ) : 20 metric tons (MT) bulk

• Loading capacity per container : 24 MT per 20′ ISO tank container (liquid) / 20 MT per 20′ dry container (flake, palletized)
