MDEA in Gas Treatment
Methyldiethanolamine is the industry-standard tertiary amine for selective removal of hydrogen sulfide from natural gas and refinery streams. Unlike primary and secondary amines, MDEA absorbs H₂S rapidly while being kinetically selective against CO₂ at low CO₂/H₂S ratios, reducing energy consumption in regeneration. Activated MDEA blends with piperazine or other promoters are widely used for bulk CO₂ removal in LNG and hydrogen production plants.
Supply to Gas-Processing and Chemical Industries
Terracore supplies MDEA in 200 L drums and 1,000 L IBCs. Gas-treating grade includes specification for water content, iron content, and MDEA assay. Pharmaceutical-synthesis grade is available on request with additional purity documentation. Full SDS and COA are standard with each delivery.
Applications
- Selective H₂S absorption in natural gas treating
- CO₂ removal from syngas and flue gas
- Pharmaceutical synthesis building block
