摘要：
Instrumentation combining feedback or feedforward pH signals with process flowrate is described. Characterization of pH based on average process titration data provides a linearized reagent demand signal for control. Advantages and limitations of feedback and feedforward control are compared in evaluating their abilities to reduce the costs of tankage and mixing in industrial neutralization systems.
