【 摘 要 】

Reduced tomography analyzed the data of cross section which no rotation and translation of the detectors and radioactive source. The main objective is investigating the industrial process in term of mechanical and process problems such as formation of catalyst/solid in multiphase packed bed column. A diameter of 0.2 m packed bed column was used in this study. The gas velocities were varied to get some movement of the particles. Multiple scanning was conducted using Industrial Process Computed Tomography instrumentation. However, only three detectors were used to collect and analyzed the data. The results were compared with other portable instruments with one source and three detectors manually. In addition, Monte Carlo modelling was conducted to get better results comparison. The results were successfully diagnostic any mechanical, and process problem such as maldistribution or channelling happen in the packed bed column.
