“…Petrochemical and chemical process industries are the main users and beneficiaries of the column scanning technology [2] In engineering applications, gamma scanning technique has been used for inspection of various processing units of industrial plants and has been reviewed [3,4] and documented [5]. Gamma scanning technique with one source-one detector was used to for multiphase flow regime of hydrocarbon in the horizontal pipeline transport [6], distillation columns [7,8], and debutanizer of Fluidized Catalytic Cracking Unit (FCCU) in petroleum plant [9]. The gamma scanning technique was also used for characterization of radioactive waste in the container [10,11].…”

Nuclear based technology called gamma scanning technique found its application for troubleshooting and diagnosing industrial process performance. The success of application of the gamma scanning technique is attributed to its unique ability in providing information which is cannot be obtained by any other techniques. One of the most prominent advantages of the gamma scanning technique was demonstrated by implementing this technology for scanning caustic/water wash tower DA 202 which was running in normal condition of operation. The DA 202 tower is trayed column having diameter of 4.2 m and height of 40 m. The scanning work has been performed using 70 mCi 60 Co isotope as gamma emitter and scintillation detector as radiation counter to investigate condition of ten trays, starting from tray # 13 at elevation of 35050 mm to tray # 4 at elevation of 26950 mm above ground level. Scan data show that all trays were in their position. Tray # 4 to tray #10 were functioned properly and carried approximately the same amount of liquid. Light flooding on tray # 11 and heavy flooding on tray # 12 were identified. Partial flooding was identified on tray # 13. Further examination at the time of shutdown it was found that the liquid flooding on tray # 12 was caused by presence of a bucket covered with solidified mud.

The gamma-ray transmission technique is well known and widely used to on-line examine inner details of industrial process column. For that purpose, a particular case study was conducted to diagnose the performance of a Naphtha Splitter Column in real time at one petrochemical plant in Malaysia. The technique employed Co-60 as a radioisotope sealed source to emit gamma radiation and a Nal(TI) scintillation as detector. This technique provides a visible representation of the true nature of the naphtha splitter column wherein the process and mechanical problems inside the column can be identified while it is in operation. This paper demonstrates details of the technique used and shows the result obtained.
