This method is used for determination of monoethanolamine (MEA) content in a fresh & regenerated solutions. MEA is most commonly used to remove acid gases, such as hydrogen sulfide and carbon dioxide from hydrocarbon streams. The method utilizes an acid-base titration that determines basic constituents, i.e., free amine and amine associated with weak acids. The value obtained is a measure of the potential efficiency of the solution to remove the above gases. The lower limit of detection is approximately 0.5 mass-%.
The sample should be free from any contamination of caustic materials like sodium or potassium hydroxide and their carbonates and also from basic material like ammonia, which also form salts with sulfuric acid and will impart a positive interference in this method.
