How the amine operation works?

Amine systems become contaminated with organic and inorganic contaminants due to various reasons. These solids can cause severe problems in the process, like foaming which causes poor system performance and corrosion which reduces equipment life time.


amine process


The system consists of the following components:

  1. Activated carbon injection system
  2. Static mixer
  3. Pre-coat tank with impellor and pre-coat pump
  4. Pre-coat particle filter
  5. Polishing filter

Problems with activated Carbon Bed Filter?

And want to get rid of it? We can assist you with this and improve the activated carbon filtration process. Carbon, removed in the pre-coat filter, is continuously added to the amine solution and mixed thoroughly in the static mixer. This method removes the surface-active contaminants and hydrocarbons that contribute to foaming.


Particle filters in combination with Activated Carbon Bed Filters are used in the amine treatment. Due the high investment cost, complex and difficult replacement of the activated carbon Sulphurnet offers a different solution.


In Sulphurnet design the activated carbon is added to the amine and will be removed in the particle filter down stream. This set up guarantees a good contact time between the activated carbon and efficient removal of the carbon. This solution offers the following advantages:

  • Prevention of amine foaming
  • Reduced corrosion problems
  • Reduced fouling problems in the process
  • Maintaining of amine efficiency and plant capacity
