Caustic Soda Liquid — Refining

Description

Product Overview
Caustic Soda Liquid (Refining Grade) is a high-purity sodium hydroxide solution (NaOH) engineered for demanding industrial neutralization and refining processes. It is primarily used in petroleum refining, alumina extraction, and chemical manufacturing to remove acidic impurities and control pH with precision. The key value proposition is its consistently low carbonate and chloride content, which minimizes scaling and maximizes process efficiency. Strategically, securing a reliable refining-grade supply mitigates production downtime risks and ensures regulatory compliance in capital-intensive sectors.

Competitive Advantage Spotlight
Superior purity consistency (≤0.3% Na₂CO₃) reduces fouling in heat exchangers; 24/7 logistics support guarantees on-time bulk delivery; backed by full MSDS, COA, and technical compliance documentation.

2. Key Specifications & Technical Characteristics

• Chemical composition: Sodium hydroxide (NaOH) solution – Refining Grade

• Purity level: 48–50% NaOH by weight ±0.5%

• Impurity limits: Na₂CO₃ ≤0.3% max, NaCl ≤0.02% max, Fe ≤10 ppm

• Physical characteristics: Clear to slightly hazy colorless liquid; density ~1.53 g/cm³ at 20°C; viscosity 60–80 cP at 20°C

• Packaging options: ISO tank (20–25MT), bulk tanker truck (25–30MT), IBC totes (1,200L), HDPE drums (200L)

• Shelf life: 12 months in sealed, temperature-controlled (5–40°C) containers away from CO₂ ingress

3. Core Industrial Applications

• Petroleum refining: Removes H₂S and mercaptans from hydrocarbon streams (MEROX, caustic wash). Performs better than lower-grade caustic due to minimal carbonate buildup, extending amine unit life by 15–20%.

• Alumina refining (Bayer process): Digests bauxite ore to extract sodium aluminate. Higher purity reduces red mud contamination, improving yield per ton of ore.

• Water treatment & chemical synthesis: Neutralizes acidic waste streams and produces sodium salts. Cost advantage from reduced scaling in dosing systems lowers maintenance frequency by 30%.

4. Competitive Advantages

• Quality consistency: Every batch IEC-60754 compliant; COA with 10+ trace contaminants available before shipment.

• Supply reliability: Dedicated stainless steel tank fleet with GPS tracking; 98% on-time delivery rate over 24 months.

• Logistics capability: Bunker/barge, rail, and road options from Gulf Coast and Rotterdam hubs.

• Price competitiveness: Fixed monthly index-linked pricing + volume rebates for >5,000MT/year contracts.

• Sustainability: Returnable ISO tank program reduces single-use drum waste; zero-liquid-discharge compatible.

• Technical support: In-house refining engineers for online dilution, storage corrosion audits, and emergency neutralization planning.
