Identify the cause of liquid maldistribution inside packed beds

Diagnosing liquid maldistribution problems inside packed beds that can cause mass transfer efficiency loss is a challenge to process engineers.

Pless, L., Tracerco

Diagnosing liquid maldistribution problems inside packed beds that can cause mass transfer efficiency loss is a challenge to process engineers. In industrial distillation columns, the potential causes of liquid maldistribution include problems with the design, manufacture or installation of packed tower internals, as well as complications from damage, fouling and other process disturbances. Gamma scan and tomography scan technologies have proven to be an essential measurement tool to supplement operating data analysis. Process engineers and operations personnel must know what is happening inside their process equipment so they can consider solutions and take corrective action.
