Diethanolamine (DEA)

Description of product

Diethanolamine (DEA) is a versatile organic chemical compound that is widely used in various industrial applications. It is a colorless, viscous liquid with an amine odor and is typically produced by the reaction of ethylene oxide with ammonia. DEA is primarily used as a surfactant, emulsifier, and corrosion inhibitor in numerous processes, particularly in the oil and gas industry.

Applications:

  1. Oil and Gas Industry:
    • Corrosion Inhibition: DEA is commonly used to prevent corrosion in oil pipelines and equipment by forming a protective layer on metal surfaces.
    • Gas Treating: It is used as an amine solution for gas sweetening, removing acidic gases such as hydrogen sulfide (H₂S) and carbon dioxide (CO₂) from natural gas and refinery gas streams.
    • Emulsifier and Surfactant: DEA is used in drilling fluids to help maintain stability and improve the performance of the emulsions in oil-based mud systems.
  2. Chemical Manufacturing:
    • Detergents and Cleaners: Used in the formulation of detergents, soaps, and cleaners due to its surfactant properties.
  3. Water Treatment:
    • DEA is used in water treatment applications to reduce the formation of scale and improve the performance of reverse osmosis membranes.
Chemical & Physical properties
Documentation
  • DEA is a hazardous chemical, and appropriate safety measures should be followed.
  • Protective Equipment: Wear gloves, goggles, and respiratory protection when handling DEA.
  • In case of skin or eye contact, immediately rinse with plenty of water and seek medical attention if necessary.
  • Storage: Store in a well-ventilated, cool area away from sources of heat, sparks, and open flames.
  • Handling: Handle in a controlled environment, avoiding exposure to large quantities of DEA.
