1. Product Overview & Technical Specifications

Monoethanolamine (MEA), CAS 141-43-5, is a versatile amino alcohol with the molecular formula C₂H₇NO. Key parameters:

2. Industrial Applications of Monoethanolamine

2.1 Gas Treatment Solutions

MEA dominates acid gas removal with 65-75% market share in CO₂ capture systems due to its high absorption efficiency (up to 90% recovery rate).

2.2 Personal Care Chemistry

In cosmetics, MEA functions as:

• pH adjuster (optimal range 5.5-7.5)
• Surfactant precursor
• Emulsification agent

3. Operational Guidelines & Safety Protocols

4. Case Studies: Real-World Implementations

4.1 Petrochemical Refinery – Qatar

Challenge: Reduce H₂S emissions from 2500 ppm to <4 ppm in LNG processing.

Solution: Implemented 30% MEA scrubbing system with temperature-controlled absorption towers.

Outcome: Achieved 98.7% sulfur recovery with 22% operational cost reduction versus previous DEA system.

4.2 Cosmetic Manufacturer – France

Requirement: pH stabilization in vegan hair care products without animal derivatives.

Implementation: 0.8-1.2% MEA concentration in shampoo formulations.

Result: Maintained consistent pH 6.2±0.1 through shelf life, achieving ECOCERT certification.
