Amine Treating Plants
- Efficiently remove CO2 and/or H2S to meet pipeline specifications and reduce corrosion
- Regenerate amine for continual use and reduced chemical costs
- Wide range of standard and custom plant sizes available
- Modular design as applicable for ease of installation and reduced field work
- Typically, amine treating plants are identified by the circulation rate in gallons per minute (GPM) of amine solution circulated in the system. Kinder Morgan Treating provides equipment ranging from 5 GPM to 2,000 GPM.
Kinder Morgan Treating Offering:
For each potential application, our process engineers perform a simulation to determine the equipment required to meet the desired specification. Once modeled, the equipment is designed and/or identified:
- New equipment: Our fabrication facility in Odessa, TX designs and builds new standard and custom amine treating plants from 25 GPM to 2,000 GPM.
- Lease Equipment: Our large lease fleet of amine plants consists of over 200 amine plants ranging in size from 5 GPM to 400 GPM.
Our typical amine treating plants incorporate:
- Robust gas trains with inlet filter separator, amine contactor and outlet scrubber that help maintain the integrity of the amine, thereby reducing operational expense and enhancing runtime
- Redundant pumps and full flow bypasses on charcoal beds and sock filters that allow the plant to continue to operate during preventative maintenance
- Flash tanks with adequate residence time to promote flash regeneration of amine, reduce the load on the reboiler and still column, and improve fuel efficiency
- Allen Bradley PLC’s with touch screens for ease of operation and integration to SCADA systems
- Larger plants use multi-stage centrifugal solution pumps that improve run time and reliability
CO2 and H2S Removal Process Summary:
Amine removes the corrosive, non-desirable CO2 and H2S (acid gas or sour gas) from natural gas streams via physical and chemical reactions in the contactor tower (absorber) to meet pipeline specifications and prevent corrosion of downstream equipment. Liquid amine/water solution flows from the top of the contactor and natural gas flows from the bottom of the contactor. Natural gas leaving the top of the tower has reduced CO2 and H2S (sweet gas) acceptable for downstream delivery. Amine leaving the bottom of the tower contains CO2 and H2S (rich amine), which is regenerated (lean amine) and sent back to the top of the contactor.
