TRACERCO Diagnostics™ ThruVision

Investigation and Analysis of Maldistribution Problems

• Map liquid maldistribution in packed columns
• Profile catalyst distribution in FCCU risers
• Identify integrity problems with column and reactor internals (packing, demister pads, catalyst beds, etc.)
• Measurement of Ice / hydrate deposits in gas lines
• Measurement of solid / liquid buildup in pipelines
• Two dimensional vessel scanning

The use of TRACERCO Diagnostics™ ThruVision Tomography system provides a powerful non-intrusive
inspection tool to examine the contents of pipe lines and vessels across a wide range of process industries. The process vessel can be a packed distillation column or a fluidized catalyst riser or standpipe where flow distribution of the process fluids is vital to performance.

The first step to determine liquid maldistribution in a packed column is to use the TRACERCO Diagnostics™ Tower Scan. This provides an initial look at the liquid distribution within the packing. If more quantitative information about liquid distribution is desired or if there is a reasonable suspicion that the bed is experiencing annular liquid maldistribution then the TRACERCO Diagnostics™ ThruVision is recommended.

The system produces 2D density maps of the contents of a vessel. The results are produced on-site and an initial report can be given by the experienced Tracerco engineers undertaking the measurements. The system is adaptable to a wide range of pipe and vessel sizes.

Tomography System

The TRACERCO Diagnostics™ ThruVision technology has proven to be a practical tool for investigating flow distributions of vapor/liquid and vapor/solid systems inside process vessels. TRACERCO Diagnostics™ ThruVision has been used in packed bed and other applications on column diameters ranging from 2 to 35 ft. (0.6 to10.7m) and in fluidized catalyst risers in reactors ranging from 0.7 to 6 ft. (0.2 to1.8m).

Applications of TRACERCO Diagnostics™ ThruVision technology has provided a new “window” for observing hydraulic phenomena inside industrial process units in real time at an economical cost.
