Gamma column scanning

Gamma column scanning

Gamma column scanning is one of the inspection techniques that is useful for distillation columns in petroleum and petrochemical plants. Thailand Institute of Nuclear Technology (TINT) can identify locations of problems in your process column.

Any problem in the process column would be figured out as soon as possible. An unplanned shutdown is a big financial and requires extra time. It would be better if we accessed value data of the columns immediately by gamma column scanning.

Advantage

• On-line inspection, no need to remove insulation.
• Reduce time of turnaround/shutdown.
• Preventive maintenance.
• Prepare a spare part before turnaround and shutdown.
• Verify the location/position of the installation internal part in the column.
• Optimization and monitoring operating process conditions.

Scanning results

• Location of problem.
• Tray damage/ missed tray.
• The height of packing bed.
• The density distribution in packing bed.
• Operation problem : Flooding, Foaming, Weeping, and liquid entrainment.
