There are many reasons, such as an inappropriate control system, improper hydraulic design, and operational faults, which can make a tower unstable. In this case, with the aid of simulation and checks on the control system, it has been confirmed using the foaming test that instability is due to foaming in the system. The method described in this article can be used for any separation system with instability problems.
