Method Measures Effective Scale-Inhibitor Concentration at Low Detection Limit

The authors of this paper develop an assay method to determine effective scale-inhibitor concentration.

The accurate measurement of residual scale-inhibitor concentration in produced brine is essential for scale prevention. However, these scale inhibitors are effective at substoichiometric concentrations in most production conditions. It is difficult to measure such low inhibitor concentration with traditional methods, especially for non- or low-phosphorous polymeric scale inhibitors. In the complete paper, an assay method is developed to determine effective scale-inhibitor concentration.
