A Tracerco Diagnostics™ FCCU study allows refiners to identify operational and mechanical issues while the Fluid Catalytic Cracking Unit is still online. The use of Tracerco’s sophisticated scanning and tracer technologies allows refiners to improve productivity, maximise throughput, and plan any maintenance effectively. The insight provided from the study will lead to greater unit efficiency and higher profitability across the units run cycle. In this blog post we will discuss the top three questions we are asked with regard to a Tracerco Diagnostics™ FCCU study.

In FCC Units (Fluidised Catalyst Cracking Units), the atmospheric residue from the distillation is cracked to LPG, naptha and other components. This sometimes leads to “invisible” deposits inside the riser.

This post is the second part of the "Diagnosing liquid maldistribution inside packed beds" series.
In the previous blog, we explained how Tracerco’s Tru-Grid™ Scan technologies can be used to diagnose suspected maldistribution in packed beds. In Part 2, we will discuss how we obtain more details on distribution within the packed bed.
A challenge to process engineers is diagnosing liquid maldistribution problems inside packed beds that can cause severe mass transfer efficiency loss. In industrial distillation columns, common examples of the cause of liquid maldistribution are design, manufacture or installation defects of distributors as well as damage, plugging and process disturbance of packed beds.
In this latest blog we will explain how following a Tru-Grid™ Scan, Tracerco’s ThruVision™ technology was able to obtain a more detailed liquid distribution profile of the packed bed.

This post is the first of the "Diagnosing liquid maldistribution inside packed beds" series.
A challenge to process engineers is diagnosing liquid maldistribution problems inside packed beds that can cause severe mass transfer efficiency loss. In industrial distillation columns, common examples of the cause of liquid maldistribution are design, manufacture or installation defects of distributors as well as damage, plugging and process disturbance of packed beds.
In this latest blog, we will explain using a case study approach how Tracerco's scanning technologies can be used to diagnose suspected maldistribution in packed beds.
The first step to determine liquid maldistribution in a packed column is to perform a Tracerco Tru-Grid™ Scan to provide an initial look at the liquid distribution in the packing. A Tru-Grid™ scan consists of four equal-distant chords, one through each quadrant of the tower. Under ideal conditions and uniform liquid loadings, each scan plot will overlay closely with all others.

A problem plaguing butadiene purification unit operations is the potential for free radical polymerisation, commonly known as popcorn polymer. This popcorn polymer formation can disrupt the operation of the unit by plugging lines, sticking valves, and even physically damaging equipment. Under certain conditions the polymer growth can push apart flanges, rupture lines and even pop the head off exchangers.
