Inlet Filter

The inlet filter is used to remove unwanted solid particles and liquid hydrocarbons from the sour gas stream before it goes through the sweetening loop.

Amine Contactor

Untreated natural gas containing carbon dioxide (C0₂) and hydrogen sulfide (H₂S) flows into the bottom of the amine contactor where it contacts countercurrent flowing amine-water from the top of the tower. The amine solution sweetens the natural gas by absorbing the C0₂ and H₂S upon contact. The sweet gas is removed overhead and the rich amine is drained and recirculated for regeneration.

Amine Regeneration

Rich amine is routed to into the amine regenerator column where the application of heat is applied to reverse the absorption of H₂S and C0₂. The lean amine is then re-circulated to the gas contactor while the concentrated acid is directed off-skid for further processing.

Amine Reboiler

The amine reboiler is part of the amine regeneration process where the mixture is boiled to release unwanted gases.

Amine Charge Pumps

Amine Charge pumps are used to increase the pressure and circulate the amine solution to the amine contactor after it is regenerated.
