Huntsman Diglycolamine DGA

Huntsman Diglycolamine DGA is a high-purity diethanolamine derivative in the Huntsman Amines series, widely used for CO₂ and H₂S removal in gas treating. Its dual-hydroxyl structure enhances reactivity, selectivity, and regeneration efficiency versus monoethanolamine. Ideal for low-corrosion, energy-efficient amine systems in natural gas and refinery applications.

Features Of Huntsman Diglycolamine DGA

  1. Highly selective for hydrogen sulfide (H₂S) removal in acid gas treating applications.

  2. Lower heat of reaction compared to monoethanolamine (MEA), enabling reduced regeneration energy consumption.

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

  4. Low volatility and minimal solvent loss during operation, contributing to improved process safety and reduced emissions.

  5. Compatible with standard carbon steel infrastructure when properly inhibited and operated within recommended pH and temperature ranges.

Typical Applications Of Huntsman Diglycolamine DGA

  1. Natural gas sweetening for pipeline specification compliance.

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

  3. Biogas upgrading to remove H₂S prior to compression or injection.

  4. Ammonia plant syngas purification to protect catalysts from sulfur poisoning.

  5. Off-gas treatment in sulfur recovery units (SRUs) and tail gas treating systems.
