Standard Practice for Extraction of Water-Soluble Amines from Crude Oils

Importancia y uso:

5.1 Amine-based scavengers are commonly used to abate sour gas from hydrocarbon streams via a stoichiometric reaction with hydrogen sulfide. Some of these amines can contribute to downstream amine-chloride corrosion and fouling of crude oil fractionation towers and overhead condensers. The detection and quantification of amine contamination is important in the planning and implementation of control measures. Water soluble amines can be extracted from crude oil at low concentrations with proper washing and isolation. Such species can be quantified using various analytical techniques including ion chromatography. This approach has been found effective for isolating key amines MEA, MDEA, and MMA among others.
