Key issues:
- Investigated concept of diaphragm actuators and control valves to transfer energy from the slurry to clean water which can then be passed through a turbine.
- Ensure constant flow caused by energy transfer
- Dynamic Simulation with control.
- Optimise control philosophies.
Methodology:
- Simulate the pilot plant.
- Compare simulation and test data for the test plant.
Solution:
- Flownex Model provided the ability to tune valve opening and closing sequences
- Pressure peaks in the system as well as water hammer scenarios were evaluated
- Optimisation the valve operating sequences and opening and closing rates.
