Diethanolamine — Gas sweetening

Description

1. Product Overview

Diethanolamine (DEA) is a high-purity alkanolamine specifically formulated for acid gas removal (H₂S and CO₂) in natural gas, refinery, and syngas processing streams. As the industry standard for selective sweetening in medium-pressure systems, DEA delivers superior absorption efficiency and reduced circulation rates compared to primary amines. Its strategic value lies in enabling regulatory compliance, asset integrity protection, and downstream catalyst life extension—making it a mission-critical consumable for global energy operators.

2. Key Specifications & Technical Characteristics

• Chemical composition: Diethanolamine (HN(CH₂CH₂OH)₂) ≥ 99.0%

• Grade: Gas sweetening / industrial high-purity

• Physical form: Clear to pale yellow viscous liquid

• Color (APHA): ≤ 50

• Density (20°C): 1.090 – 1.095 g/cm³

• Equivalent weight: 105.1 g/eq (active amine basis)

• Water content: ≤ 0.5%

• Packaging options:

  • 225 kg net steel drums

  • 1,100 kg IBC totes

  • Bulk ISO tank containers (20 MT)

• Shelf life: 24 months in original sealed container under dry, ambient conditions

3. Core Industrial Applications

• Natural gas processing: Selective removal of H₂S and CO₂ from sour gas streams (3–8% acid gas) at mid-range pressures (300–800 psi), enabling pipeline-spec gas sales.

• Petroleum refining: Amine treating of LPG, fuel gas, and liquid hydrocarbon streams in Claus sulfur recovery units; reduces downstream corrosion and protects Claus catalysts.

• Syngas & hydrogen plants: Acid gas scrubbing upstream of methanation or ammonia synthesis; DEA minimizes co-absorption of valuable hydrocarbons.

• Why DEA outperforms alternatives: Compared to MEA, DEA offers lower regeneration energy (≈15–20% savings), reduced solvent losses, and higher selectivity for H₂S over CO₂. Versus MDEA, DEA provides faster kinetics in moderate-acid-gas applications.

4. Competitive Advantages

• Quality consistency: ISO 9001:2025 certified production with batch-specific COA; trace amine impurities (≤0.3% TEA, ≤0.2% MEA) guaranteed.

• Supply reliability: Redundant production lines + buffer stock in three regional hubs (Americas, Europe, Middle East) ensures ≥99.5% on-time delivery.

• Logistics capability: Dedicated amine fleet including stainless steel ISO tanks, heated for cold-weather regions; demurrage risk mitigation contracts available.

• Price competitiveness: Direct-from-manufacturer pricing with volume-based tiering—no distributor markup.

• Sustainability: DEA is non-PFAS, fully recyclable via reclamation services partnership; residual amine waste can be incinerated for energy recovery with low NOx profile.

• Technical support: Full amine analysis (degradation, heat-stable salts, foaming tendency) included with bulk orders; process simulation support available.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20 MT (single ISO tank or flexibag in container)

• Loading capacity:

  • 20′ ISO tank container: 20 MT net

  • 40′ HC with 2 × IBC totes: 2.2 MT (not cost-optimal; bulk recommended)

  • Standard break-bulk: 20 MT per 20′ container (flexibag configuration)
