Tracerco’s technologies provide actionable information on trayed towers when the system is operating, whether in normal, test, or upset conditions. A Tru-ScanTM diagnosis delivers better insights on tray conditions, including flooding, foaming, weeping and internal damage. Our patented FrothViewTM technology offers another level of detail, quantifying total froth height on individual trays. This is displayed as % tray space, and has been shown to correlate very well with % flood. The measurement has been validated with pilot plant studies, matching model predicted froth heights.
Tru-ScanTM and PhaseFinderTM technologies are an important measurement to take during or when restarting your operations. Tru-ScanTM can be used to measure the liquid level in towers quickly and efficiently if you suspect there is a problem. This technology could help your business make a significant financial saving.
A Tracerco DiagnosticsTM Helium study is a unique service, detecting air ingress in vacuum columns. There is potential for air ingress to occur in areas such as a gasket flange, threaded fitting, sight glass, block valve and valve stem. Therefore, a Tracerco DiagnosticsTM Helium study can assist in decreasing downtime, reducing maintenance and repair costs, and securing process system integrity.
Baseline scans are highly recommended when a distillation column is clean, known to be in good mechanical shape, and operating with no known problems. It eliminates the uncertainty for future column troubleshooting scans that aid in diagnosing subtle operational changes. Baseline scans can also be used to assess the effects of tower revamps, to document the start-up of a column and to ensure it has made it through without any damage.
In fouling services, a baseline scan provides a profile of the column internals at their cleanest. The column can be scanned over time to monitor build-up, which can help establish operating parameters that may slow the fouling process down and prolong running times. This will give you a better idea of when the fouling is near critical levels, and allows you to plan for outages, instead of having to shut down on an emergency basis. This in turn will reduce downtime.
Pre-turnaround scans help avoid turnaround surprises and allow you to manage costs. By defining and developing a turnaround project scope at an early stage, you will be able to identify columns with process issues, rather than mechanical issues. Pre-turnaround scans allow for columns to be removed from your overall turnaround package, saving time, excessive costs associated with emergency tray or packing orders, and having to extend downtime.
The TracercoTM Insights Platform provides fast, secure and convenient access to your process insights, allowing you to rapidly and confidently optimise your process and increase efficiencies. With its cloud-based reporting, you can track the status of tower scanning projects, explore interactive reports and access a library of your historic tower scan data from wherever you are in the world. Being able to visualise and understand changes, you can identify potential issues quickly, saving valuable time and money associated with remediation costs.
Scans do not directly detect fouling (unless a non-operating scan is done). Scans detect density or density differences. Scans cannot detect the difference between density caused by solids or density caused by liquid. What scans do detect is how fouling affects the liquid traffic in a piece of equipment. If a scan detects more liquid in a location than should be there, the question is why? Fouling could be one reason. The absolutely best way to monitor or determine fouling effects is to use a baseline scan for a hydraulic profile before there is any fouling present. Then after time when and where fouling forms and starts to have an effect it will be more readily obvious by comparing scans to the baseline.
