Significance and Use
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.
Scope
1.1 This practice covers a procedure for extraction of water-soluble amines in crude oil for subsequent measurement by undefined analytical techniques. This practice is applicable to crude oils and is intended to provide guidance on water washing crude oil for optimal recovery of amines at low concentrations.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
