A Direct Measurement Method for the Characterization of Corrosion Inhibitors for Quality Metrics in Formulation and New Product Development
Corrosion costs the petroleum industry an estimated $1.3 billion in non-productive time, materials and labor annually. Imidazolines prepared from fatty acids and amines are a widely-used class of chemical corrosion inhibitor, due to excellent performance and ease of handling. However, commercial imidazolines are actually mixtures of several different chemical compounds, and the relative proportions of these species can have a large impact on both corrosion inhibition and product physical properties. The absence of gold standard analytical methods to characterize the active ingredients in imidazoline formulations limits the understanding of the chemistry of these materials. It is for this reason that a SPE-LC-MS method was developed to supplement the chemical information afforded by bulk testing / wet chemistry methods. It is anticipated that this method will have significant impact in the formulation of new corrosion inhibitors for oilfield applications as well as the quality control of finished products in manufacturing.
