Amine Filtration

Filtration plays a crucial role in the design of an amine system and is essential for optimal operation. The effectiveness of the system relies on the cleanliness of the amine, making filtration the top choice for eliminating contaminants like solids, liquid hydrocarbons, and heat stable salts. Removing these contaminants greatly improves the performance of the system and also has the following benefits:

  • Preventing the generation of foam caused by amines
  • Minimizing the occurrence of corrosion and fouling issues during the manufacturing process
  • Lowering the amount of amine used
  • Sustaining the effectiveness of amines and ensuring optimal plant capacity.

Amine filtration is used in two locations of gas sweetening unit, at the bottom outlet of and at the top inlet of absorber. They consist of three parts with below duties:

  • Liquid Particle Filter: removal of scale and solids to protect carbon filter
  • Carbon Filter: removal of dissolved organic acid and hydrocarbons
  • Liquid Particle Filter: removal of carbon bed fines
