pH Process Modeling and Control Simulation in Industry 4.0.

CyboSoft has released a Real-Time pH Process Modeling and Control Simulation Software package. It is the first in CyboSoft's virtual plant software family to help engineers learn how a pH process behaves, and how to effectively control this extremely nonlinear process to comply with EPA wastewater discharge codes and save chemical reagent.

CEO Dr. George Cheng said, "We are entering the era of the 4th Industrial Revolution, where everything is supposed to be 'smart'. Ironically, about 90% industrial wastewater pH processes are still controlled by on-off Bang-Bang control, resulting in chemical reagent wastes, equipment corrosion, and environmental pollution. It is our mission to provide software tools and control solutions to help the industry improve control systems and achieve better safety, higher quality, and lower costs."

The Real-Time pH Process Modeling and Control Simulation Software is built in National Instruments' LabVIEW platform and includes:

(1) pH process diagram,
(2) a strong-acid-strong-base pH model,
(3) a weak-acid-strong-base pH model,
(4) a strong-acid-weak-base pH model,
(5) a weak-acid-weak-base pH model,
(6) MFA control simulation for the 4 pH processes using an MFA pH controller,
(7) PID control simulation for the 4 pH processes,
(8) On-Off control simulation for the 4 pH processes,
(9) graphical interface with control faceplates and real-time trends,
(10) LabVIEW diagrams, and
(11) pH process model description, MFA controllers used, and recommended control strategy.

"Most process models are presented as mathematical equations or formulas, which are important but have limited usage. A real-time process model can be used as a virtual process to simulate a real process with minimal setup time and cost. Using a virtual plant software tool to solve real problems is a powerful and cost-effective way to help build a Smart Industry," Dr. Cheng added.

CyboSoft's pH process models are delivered as VIs (virtual instruments) in LabVIEW. The user can design and test their pH control systems using the pH process models running in real-time. For instance, a pH process model can run in a PC with real-time interface to a popular pH controller on the market or to an existing pH controller in service. The control results can be compared with the MFA pH control results obtained in MFA control simulations. The user can then take the results, estimate the chemical reagent savings, and show the potential return-on-investment (ROI) when applying for budget to buy the proper pH controller or control software to improve pH control performance.

CyboSoft will release a number of real-time process modeling and control simulation software products in its virtual plant software family that can be purchased from CyboSoft's online store. The pH Process Modeling and Control Simulation Software can also be purchased from National Instruments' Tools Network store, where a 30-day trial version is available. Customers can contact CyboSoft for various MFA control products or for consulting and engineering services. The pH control device vendors can contact CyboSoft for embedding MFA pH control software in their devices.
