Simulators of tray distillation columns as tools for interpreting gamma–ray scan profile signals
Simulators of tray distillation columns were used to provide technical guidelines for interpreting signals from gamma ray scans used for analysing malfunctions in distillation columns. The transmitted radiation intensities at 0.05 m intervals were determined from top to the bottom of simulators of tray distillation columns exposed to 20 mCi of 137 Cs. Signals generated from the simulators were identical with the experimental signals obtained from the Stabilizer Column of the crude oil distillation unit at the Tema Oil Refinery Ghana Limited. Changes in the signal level were observed with changes in diameter, type of material (gasoline, air, debris, steel) and orient-ation of scan line. The analysis provided accurate interpretation of gamma scan profiles.
