How to identify deposits inside the riser of a FCCU

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.

How to diagnose liquid maldistribution in packed beds: A case study - Part 2

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.

How to diagnose liquid maldistribution in packed beds: A case study - Part 1

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.

How to minimise maintenance costs with exchanger leak testing: case study

Posted by Callum Grieves

Detecting and identifying small leaks in heat exchangers can be an extremely difficult and time consuming task for many operators and plant personnel. Product quality, process efficiency and the time and cost associated with maintenance and potential shutdowns caused by a leaking vessel can have a significant and detrimental impact on production and process operating margins.

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.
