Strong Acid Equivalent Control of pH Processes: An Experimental Study Conference Paper uri icon


  • The authors' approach to controlling pH consists of defining an alternative equivalent control objective, the strong acid equivalent, which is linear in the states, and using a linear control law in terms of this new control objective. The strong acid equivalent is then calculated on line from pH measurements given a nominal titration curve of the inlet stream. A laboratory system has been built to implement this method. Experimental results for the hydrochloric acid/sodium hydroxide and acetic acid/sodium hydroxide systems are given. The results show the control which can be achieved with the strong acid method.
