Title: Differentiating the Performance of Co and Ter Polymers in Static and Dynamic Laboratory Studies
The objective is to educate the audience on new innovative methods for evaluating scale inhibitor chemistries.
Scale inhibitor type selection
Phosphate/carbonate inhibition from intended or incidental sources
Formulation optimization for various stress factors
Evaluation of deposit control agents is a recurrent process as new products and test methods are developed. Deposit control polymers (DCPs) are optimized for effective control of carbonate, phosphate, sulfate, and silicate scale. A chemical analysis of the polymer can highlight chemical differences but, proof of performance is determined on the ability of the polymer to control the precipitation of inorganic salts. Laboratory screening methods have been utilized for years, however, these studies are conducted in a controlled environment & actual field applications involve a variety of variables that cannot always be simulated or predicted by individual experiments.
In order to maximize the predictive capabilities of DCPs, this study utilizes both static and dynamic testing to evaluate carboxylate/sulfonate-based copolymers and terpolymers of varying molecular weight and functional groups on their ability to inhibit inorganic salt precipitation.
