Abstract (en)

[origin: WO2023033825A1] Systems and methods for applying a chemical treatment solution to a process stream in an industrial processing system while the system is online. The method includes measuring a real-time pH of the process stream, determining a dosage of the chemical treatment solution based on a relationship between the dosage and a scale saturation parameter that is calculated based on the real-time pH of the process stream, and controlling application of the chemical treatment solution to the process stream based on the determined dosage.
