Kinder Morgan Treating is an industry leader for treating natural gas to remove CO2 and H2S. We manufacture equipment for purchase at our 84-acre, ISO 9001 & ASME Code Southtex facility in Odessa, Texas. We offer amine plants ranging from 25 GPM to 2,000 GPM. Our modular plant construction reduces time and material spent on installation, and reduces the overall impact on the project site.

Our typical amine plants include standard features to improve runtime and reliability:

  • Inlet and outlet separators to preserve amine integrity
  • Backup solution pumps and filter bypasses
  • Flash tanks to reduce boiler duty and improve fuel efficiency
  • Allen Bradley PLCs (programmable logic controllers)
  • Centrifugal solution pumps to promote runtime and reliability

AmineAmine treating: Amine removes CO2 and H2S (acid gas or sour gas) via physical and chemical reactions in the contactor tower (absorber). This pressure vessel is typically the tallest component of an amine plant, in order to provide adequate residence time and control vapor-liquid flooding condition within design guidelines of the tower internals (trays or packing). Liquid amine/water solution flows from the top down and natural gas flows from the bottom up. Natural gas leaving the top of the tower has reduced CO2 and H2S (sweet gas) and amine leaving the bottom of the tower contains CO2 and H2S (rich amine).

Amine regeneration: From the contactor, amine flows through a flash tank where a pressure drop allows some of the acid gas to flash into a vapor (flash gas) that is separated from the liquid. The liquid amine continues through a heat exchanger, filters, boiler and finally through the still column (stripper). In the still, hot steam breaks the chemical bonds between the amine and the acid gases. Liquid amine/water solution flows from the top down and steam flows from the bottom up. Amine leaving the bottom of the column has reduced CO2 and H2S (lean amine) and steam leaving the top of the tower is cooled to condense the water (reflux), while the non-condensable vapor (acid gas) is combined with the flash gas and routed to plant outlet (vent gas). An amine regeneration plant (regen) requires electricity to drive the motors, fuel gas to fire the steam boiler (reboiler) and chemical makeup (amine and water).

Through a closed-loop, regeneration process, an amine plant typically provides the most cost-effective solution for a wide range of natural gas treating applications. Over the years, advancements in amine chemistry have yielded new amine formulations (e.g. DEA, MDEA, MEA and DGA). In the hands of experienced plant operators, the process has been in use for decades establishing a strong track record of reliability and efficiency. Kinder Morgan Treating employs more than 60 plant operators and we have process engineers on staff to select the right amine for your application.
