The Gas Sweetening System, also known as the Amine gas treatment plant, serves the purpose of treating sour gas, which typically contains hydrogen sulfide (H2S) and carbon dioxide (CO2), commonly present in raw natural gas streams. When CO2 combines with water, it forms carbonic acid, an extremely corrosive mixture. Additionally, concentrated amounts of H2S pose significant toxicity risks, necessitating the safe and prompt removal of these compounds to prevent harm to both equipment and personnel.

The frequency of servicing Amine plants varies depending on their size and design. Some plants require continuous 24/7 service, while others can operate for up to a week without service, ensuring the system and its components are functioning optimally. Proper functionality of parts is crucial in Amine plants, as corrosive environments can lead to rapid degradation.
