pH Control

Develop a correlation between the buffer stream value position and the buffer stream flow rate that allows a desired buffer flow rate to be established manually. Determine operating conditions that provide a neutral pH. Use the PI tuning parameters for the acid, base, outlet flow and level controllers obtained by the previous group. Collect dynamic process data by introducing various step changes in the acid, base and buffer flow rates. Develop a dynamic model of the pH neutralization system based on the concept of reaction invariants. Simulate the dynamic model for step changes in the acid, base and buffer flow rates and compare the simulation results to the corresponding experimental data. Assess the quality of the dynamic model. |
