Amine gas treating system with field-proven

Hydrogen sulfide, Carbon dioxide,and other contaminations are often found in natural gas streams. Amine gas treating systems remove these contaminations so that the gas is suitable for transportation and use.

  Overview – Amine gas treating systems

  • Prepare natural gas for commercialization

Custom and standard Amine gas treating systems remove CO2 and H2S, resulting in gas with <2-mol% CO2 and <4-ppm H2S. Efficiently removing CO2, H2S, and mercaptans makes the gas suitable for transportation and use.

The amine plant can be installed as a stand-alone component or as a part of an integrated processing system. We can custom engineer solutions for amine recirculation rates above 700 galUS/min [2.64 m3/min], and we offer five standardized designs for rates below 700 galUS/min. Years of gas sweetening expertise is built into the design and engineering of our standardized gas plants. So you can expect to achieve performance comparable to a custom-designed sweetening plant.

  • Amine treating advantages

    • Various heat sources (direct-fired, waste heat, hot oil, and steam systems) can be used for the still reboiler.
    • Customized plants can be designed to customer specification while maintaining fast delivery.
    • Our amine systems can meet required CO2 and H2S levels operating with multiple solvent types and recirculation rates.
    • Standard system designs reduce manufacturing and commissioning times.
    • Amine systems are easily combined with other technologies into hybrid systems for many sizes of gas sweetening projects.

   Application of Amine gas treating systems

Amine sweetening process as following:

  1. Sour gas enters the contactor tower and rises through the descending amine solution.
  2. Purified gas flows from the top of the tower.
  3. The amine solution, carrying absorbed acid gases, leaves the tower for the heat exchanger or optional flash tank.
  4. Rich amine is heated by hot regenerated lean amine in the heat exchanger.
  5. Rich amine is further heated in the regeneration still column, by heat supplied from the reboiler.
  6. Steam and acid gases separated from the rich amine are condensed and cooled, respectively, in the reflux condenser.
  7. Condensed steam is separated in the reflux accumulator and returned to the still. Acid gases may be vented, incinerated, or directed to a sulfur recovery system.
  8.  Hot regenerated lean amine is cooled in a solvent aerial cooler and circulated to the contactor tower, completing the cycle.
  9. A variety of heat sources can be used for the still reboiler—direct fired, waste heat, hot oil, and
    steam systems.
