Pre-turnaround scans are very useful tools for facilities to utilise for planning turnaround projects. They can indicate some damage within a vessel, allowing for parts to be ordered and onsite ahead of time. They can also indicate an operational issue, which can be corrected without an entry into the vessel. If required they can indicate that the vessel is healthy and no work is needed on it at this time.

Baseline scanning is critical to diagnose future column problems
Jan 18, 2021 8:49:22 AM
Baseline scans of a vessel are undertaken when it is known to be clean, operating normally, and in good mechanical condition. They are often used for comparison purposes on future troubleshooting scans. Any anomaly, or abnormal absorption observed on a baseline scan, that cannot be explained by a visible external interference or by something indicated in the column drawings, may be able to be eliminated as a potential problem area in future troubleshooting scans.

Diagnosing the cause of off-spec production in a distillation column: A case study
Jul 21, 2016 7:53:47 AM
Tru-Scan™ and Tru-Grid™ scans are powerful tools that give you valuable insights into packed and trayed towers, tanks, pipes and more. Using this field-proven predictive maintenance technique on distillation columns allows plant personnel to monitor tray or packing hydraulics. A sophisticated monitoring programme can track the effects of fouling or other incapacitating conditions to extend run times and identify maintenance requirements in advance of scheduled turnarounds.
