1. A method for applying a chemical treatment solution to a process stream in an industrial processing system comprising a heat exchanger, the method comprising, while the system is online:
measuring a mineral hardness and alkalinity of the process stream;
measuring an inlet-side temperature and an outlet-side temperature of the heat exchanger and determining a skin temperature of the heat exchanger based on the inlet-side temperature and the outlet-side temperature;
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 mineral hardness and the alkalinity of the process stream, and the skin temperature of the heat exchanger; and
controlling application of the chemical treatment solution to the process stream based on the determined dosage.
