Monoethanolamine — CO₂ / H₂S removal

Description

1. Product Overview

Monoethanolamine (MEA) is a proven alkanolamine solvent engineered for the selective absorption of carbon dioxide (CO₂) and hydrogen sulfide (H₂S) from natural gas, refinery off-gases, and synthesis gas streams. Its primary industrial use is in amine gas treating units (AGRU) where it chemically binds acid gases, enabling downstream purification and sulfur recovery. The key value proposition is a combination of fast reaction kinetics, high loading capacity, and reliable thermal stability under cyclic regeneration. With tightening emissions regulations and expanding LNG capacity, MEA remains a strategically indispensable molecule for decarbonizing industrial gas streams.

2. Key Specifications & Technical Characteristics

• Chemical composition: Monoethanolamine (2-Aminoethanol), CAS 141-43-5, ≥99.5% min.

• Physical characteristics: Clear, colorless to pale straw liquid; mild ammonia-like odor; kinematic viscosity ~24 cSt @ 20°C; density 1.012 g/cm³ @ 20°C

• Purity grade: Gas treating grade – low chloride, low iron, low diethanolamine content

• Packaging options: ISO tanks (20–24 MT), IBC totes (1,000 kg net), 210 kg steel drums

• Shelf life: 24 months when stored under nitrogen blanketing in sealed, corrosion-resistant containers

3. Core Industrial Applications

• Primary industries: Oil & gas (upstream and refining), petrochemicals, biogas upgrading, ammonia and hydrogen production

• Operational use cases:

  • Natural gas sweetening (removing H₂S to pipeline spec <4 ppm)

  • Flue gas CO₂ capture for EOR or sequestration

  • Tail gas treatment in Claus sulfur recovery units

• Performance advantages over alternatives:

  • Faster CO₂ absorption kinetics than MDEA or DEA, requiring shorter contactors

  • Lower heat of reaction (partial) for certain CO₂ slip applications vs. hot carbonate

  • Higher base strength enables deeper H₂S polishing without co-absorbing hydrocarbons

4. Competitive Advantages

• Quality consistency: ISO 9001:2025 certified with batch-to-batch CV <0.3% purity and controlled oxidative degradation precursors

• Supply reliability: Dual-feedstock (EO and bioethanol) production sites in three continents, with 4-week lead time guarantee

• Logistics capability: Dedicated stainless steel ISO tank fleet for amine-grade product, preventing iron contamination

• Price competitiveness: Long-term ethylene oxide contracts allowing price stability ±5% over 12 months

• Sustainability benefit: Option for mass-balanced bio-based MEA (ISCC PLUS certified) reducing carbon footprint by 70%

• Technical support: Full process simulation support (Aspen HYSYS files), corrosion inhibition advisory, and reclaiming service contracts

5. Commercial & Supply Information

• Minimum order quantity (MOQ): Bulk – 20 metric tons (one ISO tank equivalent)

• Loading capacity: 20–24 MT per 20-ft ISO tank container (direct-to-process shipment)
