Description
1. Product Overview
Diethanolamine (DEA) 99% is a high-purity alkanolamine widely used in gas sweetening processes to remove acidic contaminants such as hydrogen sulfide (H₂S) and carbon dioxide (CO₂) from natural gas and refinery gas streams. Its balanced reactivity and absorption capacity make it a reliable solvent for amine gas treating systems across oil, gas, and petrochemical operations.
With a 99% purity specification, DEA delivers stable performance, efficient acid gas removal, and long operational life in industrial absorption systems. Strategically, it plays a critical role in ensuring regulatory gas quality standards, protecting downstream equipment from corrosion, and enabling efficient hydrocarbon processing across global energy markets.

Performance & Cost Advantages
DEA provides an optimal balance between absorption efficiency and regeneration energy requirements, making it particularly effective for moderate acid gas concentrations. Its chemical stability and relatively low vapor pressure minimize solvent losses during operation.
Compared with more aggressive amines, DEA reduces corrosion risks and operational maintenance requirements in many gas treating systems. This balance of performance and stability makes it a cost-efficient solution for continuous industrial gas purification processes.
