In present paper, an integrated software system for the γ ray nondestructive monitoring and troubleshooting of both trayed and packed distillation columns was realized on the IBM PC/XT personal computer. The software system consists of the controlling and sampling program, the data processing program, and the plotting program. With the support of the controlling and sampling program, the hardware system can automatically perform axial elevating and locating, one-way or return scanning, empty and full column reading calibration. The Chinese character menu driven user interface made the operation easy and convenient. The sampled data were stored in binary data files and could be further processed by the data processing program to output the position-pulse data files or the position-density data files, which were served as the input of the plotting program. The plotting program Grapher developed by Golden Software Inc. has been employed to process the scanning data and thus the position-pulse curves or the position-density curves could be produced. These curves make it possible to analyse the hydrodynamic behavior and malfunction of distillation column in operation. The success of the software system stated above has been evaluated on a bench-scale trayed distillation column and a bench-scale packed distillation column. This would provide a basis for further industrial application of the γ ray scanning technique.
