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
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.
