OUTLINE
OBJECTIVES
To gather information on the condition of the vessel at
varying process parameters
To make an assessment prior to arranging necessary maintenance operations
Column Diameter = 1m
Wall Thickness = 10mm Total height to be scanned =
440cm
Number of scans = 12

Blockage below Tray 1
Blockage on top of Tray 2
Partial blockage on top of
Tray 4
Flooding during Scans 3 & 8
RESULTS
Gamma column scanning was able to identify blockage that caused the anomalies in the flow of liquid inside the rectifier column.
Result of gamma scanning provided necessary information for
planning efficient repair and maintenance operations.
