Removing Acid Gas and Carbonyl Sulfide from Hydrocarbon Streams

AMINEX | Amine Extraction of Contaminants

Developed by Merichem Technologies’ AMINEX is a proven technology for the removal of acid gas (H2S) and carbonyl sulfide (COS) from LPG-type liquid and gas streams.

Both technologies use Merichem Technologies’ FIBER FILM® Contactor device for mass transfer, with the appropriate amine as the treating reagent.


AMINEX technology, used with Merichem Technologies’ proprietary FIBER FILM® Contactor, helps our clients in a number of ways:

  • Reduced capital expenditures
  • Less plant space required compared to other treating alternatives
  • Faster and more efficient mass-transfer process
  • Proven technology

FFC Plus Technology

The latest iteration of Merichem Technologies’ FIBER FILM® Contactor technology, FFC Plus can increase hydrocarbon treating rates by up to 150 percent as compared to earlier designs.
