Description
Gamma ray scanning technique has been demonstrated to investigate the performance of trayed column in a petrochemical company. The trayed column is a caustic/water tower of having diameter of 4.2 m and 40 m height. The multigrid scanning was performed using 70 mCi of Co-60 gamma source and scitillation detector. Ten trays, starting flrom tray # 13 at elevation of 35.050 mm to tray # 4 at elevation of 26.950 mm above groun level. Scan data show that all trays were in their potisitons. Tray # 4 to tray # 10 were functioned properly dan carried approximately the same amount of liquid. Light liquid flooding on tray # 11 and heavy flooding on tray # 12 were identified. Partial flooding was identified on the tray # 13. At the time of shutdown, the scanned data was verified and it was found that the liquid flooding on the tray # 12 was caused by presence of a bucket on that tray, covered with solidified mud.
