Chilled water issues
A cooling water closed loop is installed in the production plant
The cooling water is used for cooling different parts of the equipment that is used in the plant.
There are two main parameters of the water: pH and conductivity. Both parameters are controlled and should be kept within certain limits.
Typically the pH of the water slightly decreases. This is compensated by adding a small amount of NaOH.
Suddenly pH started to reduce faster than usual. The compensation requested much more amount of NaOH which may result in a strong increase in the conductivity.
A regular audit showed that some flanges are affected by strong corrosion as shown below:

The project addresses instability in the dissolution of tantalum (Ta) anodes in hydrofluoric acid (HF), where hydrogen gas generated during the reaction becomes trapped in the solution, forming foam that disrupts the process and creates safety risks. Using the PRIZ Platform, a Functional Model of the system was developed. The model revealed that the HF solution is both the most functional and the most problematic component, leading to a physical contradiction: HF must interact with Ta anodes to enable dissolution, but must not retain the hydrogen gas produced during the reaction. Applying the PRIZ principle of Separation in Space, two reactor concepts were proposed: a spray interaction reactor, where HF is pumped to spray onto anodes placed above the solution, and a surface wetting reactor, where anodes are positioned at the top of the solution, allowing natural circulation and easy hydrogen release. Both designs eliminate foam formation and provide a stable, controllable, and safer dissolution process.
