The top three questions we are asked about our tower scanning technology

It is common in many oil refineries, chemical, ethanol and ammonia plants, for critical process equipment to experience problems. Issues in trayed towers such as internal tray damage, missing trays, plugged downcomers and tray foaming can all lead to off-spec production and in some cases, un-anticipated shutdowns. Scanning technology can help you avoid these scenarios by providing you with an assessment of your operating conditions, whilst your process equipment remains online. In this blog post we will feature the top three questions we are asked with regard to Trayed Towers and our Tru-Scan™ technology

Measuring the depth of refractory inside steel walls

Every refinery invests a tremendous amount of time and money in planning a unit turnaround. Scheduling of the tasks, manpower and equipment has to be detailed and thorough. In order to plan, information is needed about the process system so that critical tasks can be planned to meet turnaround time constraints. Some of this condition-based information is gathered using tools such as gamma scans, radiography, ultrasonic probes, vibration monitors, acoustic sensors, and other non-destructive techniques whilst the process is still operating. It is vital to be aware of any internal damage to distillation columns, heat exchangers, reactors, and other vessels to avoid surprises that can disrupt the turnaround schedule. Each day of downtime is a day of lost production, so it is critical that a turnaround is not extended due to unexpected repair work.

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.

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.

Jul 21, 2016 7:53:47 AM

Tru-Scan™ and Tru-Grid™ scans are powerful tools that give you valuable insights into packed and trayed towers, tanks, pipes and more. Using this field-proven predictive maintenance technique on distillation columns allows plant personnel to monitor tray or packing hydraulics. A sophisticated monitoring programme can track the effects of fouling or other incapacitating conditions to extend run times and identify maintenance requirements in advance of scheduled turnarounds.

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

Posted by Nicola Porter

Jun 8, 2016 11:35:29 AM

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.
