... of two stages. In a first stage, a membrane system is used to reduce the inlet feed gas bulk H 2 S and CO 2 concentrations. Consecutively, the sweet gas product final specifications are met using an amine-based system. Ultra-sour gas (e.g., 25% H 2 S) is considered to be treated. The study uses...

Paper Number: SPE-177406-MS
... Abstract Organic amines are corrosion control agents that increase pH and scavenge corrosive contaminants. Their presence in sour water can lead to the formation of heat-stable salts, resulting in potentially corrosive deposits. The measurement and monitoring of amines in sour water requires...

.... In this study, we examined the relationship between the electronic structure and inhibition performance of the compounds in an atmospheric corrosion test. The condensation products have significantly lower vapor pressure than parent amines, resulting in longer residence times of inhibitor species at a metal...
