Tricom Scan provides a specialized process investigation service and an efficient means of finding out the inside problems of column. • Our personal have many years in the industry, and they have performed hundreds of scans of columns. • The problems we can find, impact sometimes in thousands or even millions of dollars in worth productions, the more quickly the problem is corrected, the lower the worth is. • Detecting the exact location and cause of the problem, allow operation to choose the best course of action to alternate it. • Gamma Scanning is a quick and reliable technology for evaluating the operating characteristics inside tray and packed tower. • Tricom Scan Gamma Scanning is a method classified as a primary investigation tool in tower diagnosis. • The presence of liquid on the trays and the absence of liquid in the vapor spaces affect the radiation that passed through the column.

Tray Tower • We place a radiation source on one side of the tower and a detector in the opposite side. Both are aligned at the top of the column, and then synchronously lower down. • The amount of radiation that passed through the column depend on the density of the material between the source and the detector. • The presence of liquid on the trays and the absence of liquid in the vapor spaces affect the radiation that passed through the column.
