Case Study: Sasol protects its cooling water system with Datacor Impulse

Sasol models pump transients with Datacor to avoid reverse rotation at 286 rpm

The customer, Sasol, faced a significant risk during a valve refurbishment project on its petrochemical cooling water system. A change in the closure time of its large valves could cause reverse pump rotation, leading to potential equipment damage and a multi-week plant shutdown. They partnered with vendor Datacor to address this challenge using Datacor Impulse for transient analysis.

Using Datacor Impulse, the vendor's team modeled various valve closure scenarios with four-quadrant pump modeling. The analysis, calibrated against field data, identified a safe operational window for valve closure between 6 and 12 seconds. This solution from Datacor prevented excessive reverse rotation and motor overcurrent, thereby mitigating the risk of a catastrophic shutdown.
