When a packed bed column is scanned, the two most common scenarios are where a single scan is performed, or scans on a 2 x 2 grid as shown in the image above.
A single "TowerScan" on a packed bed column will determine:
By performing and analyzing a full 2 x 2 grid scan, our engineers evaluate:
The initial scan (red) showed that the demister pad, distributor, packed bed, and chimney tray were at the proper elevations. The bed however had experienced severe fouling, especially in the bottom two thirds of the packing. The column was shut down and the packing replaced.
The scan taken after the turnaround (blue) exhibited a far more uniform bed density. Some higher densities were seen at the top and bottom of the bed due to the hold down plate and bed support, and part way down the bed due to external mechanical interference.
