| Abstract: | Gamma scanning technique is used for troubleshooting
most of the problems of distillation columns. However, optimization of the
column at design stage or during operation requires higher sensitivity,
improved performance and reliability which conventional gamma scanning
technique lacks to provide. The paper elaborates new
approach used in gamma scanning to improve the accuracy and reliability of the
technique. The results presented here are of a laboratory study carried out
using two gamma ray energies and a sample column simulating problem between the
tray spaces, and by scanning it using Cs-137 and Co-60 radiation sources. The
raw data is then processed to obtain ratio profile of the sample column. The
ratio profile is found to be more sensitive in detecting column problems. The
interpretation of ratio profile appears much easier than conventional gamma
profile. The laboratory study suggests that dual energy scanning technique has
potential to improve the overall sensitivity and performance of the gamma
scanning technique. |
