Neutron Scan - Tanks

Benefits of TRACERCO Diagnostics™ Scan

• Determine sludge and product levels
• Inventory of vessels where more than one material is present
• Verify level indicator is working correctly

The TRACERCO Diagnostics™ Scan application uses a source of high energy or “fast” neutrons with a neutron detector that is sensitive to low energy, or “slow” neutrons. When the neutron source/detector tandem moves across a liquid/vapor interface such as water and nitrogen, then a large change in detector response is observed due to the hydrogen concentration difference between the water and nitrogen. At interfaces between materials of different hydrogen concentration, such as oil and water, then a smaller magnitude change in detector response would be observed. In general, the greater the difference is in the concentration of hydrogen nuclei between two or more substances, the greater the magnitude of change in the detector response.

Routine scans of tanks and spheres can determine sludge and product levels and if there are any plugging issues on vent lines. Results from the neutron scans are available on-site, allowing operators optimal time to schedule shutdowns and preparation of the storage facility for startup.
