Features Of Huntsman DGA Diglycolamine

  1. High selectivity for hydrogen sulfide (H₂S) removal in gas treating applications.

  2. Lower heat of regeneration compared to monoethanolamine (MEA), reducing energy consumption.

  3. Excellent thermal and chemical stability under typical amine loop operating conditions.

  4. Reduced corrosion potential relative to primary amines when properly formulated and controlled.

  5. Compatible with standard carbon steel infrastructure in well-managed amine systems.

Typical Applications Of Huntsman DGA Diglycolamine

  1. Natural gas sweetening for pipeline specification compliance.

  2. Refinery fuel gas and LPG treating to meet sulfur specifications.

  3. Biogas upgrading to remove acid gases prior to compression or injection.

  4. Coal gasification syngas conditioning for downstream processing.

  5. Offshore platform gas treatment where operational efficiency and reliability are critical.
