Amine Treating Equipment for Natural Gas Sweetening

What Is an Amine Gas Treating Plant?

Amine treating, also called gas sweetening or acid gas removal, uses alkanolamines to remove hydrogen sulfide (H₂S) and carbon dioxide (CO₂) from natural gas. These contaminants create serious safety, environmental, and operational issues:

  • H₂S is extremely toxic, even at low concentrations
  • CO₂ can cause freeze-ups in cryogenic processing systems
  • Both gases contribute to pipeline corrosion and reduce gas quality
  • Pipelines typically require gas to contain less than 4 ppm of H₂S and no more than 2–3% CO₂. In cryogenic applications, CO₂ content may need to be as low as 50 ppm.

Selecting the Right Amine Solvent

Choosing the right amine is critical to system performance. We assist with selecting the most suitable solvent based on your process, pressure, and outlet specifications.

Common Amine Types:

  • DGA® (Diglycolamine®): Ideal for low-pressure, oxygen-rich, or tight spec applications
  • MDEA (Methyldiethanolamine): Selective for H₂S, allows some CO₂ slip
  • DEA (Diethanolamine): Often combined with MDEA to reduce CO₂ slip
  • Formulated Solvents: Specialty blends for unique treating challenges

How the Amine Sweetening Process Works

  • 1Sour gas enters the contactor tower and rises through the descending amine.
  • 2Sweetened gas flows from the top of the tower.
  • 3The amine solution is now considered Rich and is carrying absorbed acid gases.
  • 4The Lean amine and Rich amine flow through the heat exchanger, heating the Rich amine and cooling the Lean amine.
  • 5Rich amine is then further heated in the regeneration still column by heat supplied from the reboiler. The steam rising through the still liberates H2S and CO2, regenerating the amine.
  • 6The acid gases flow out of the top of the still tower and are cooled to separate them from the, now liquid, water.
  • 7The condensed water is separated in the reflux accumulator and returned to the still while the acid gases are sent to flare or containment.
  • 8Hot, regenerated, Lean amine is cooled in an aerial cooler and circulated to the contactor tower, completing the cycle.
