Tracerco provides cost-effective monitoring methods for packed bed towers as well as trayed towers. Our Tru-GridTM Scan technology provides a density profile of the process, providing detailed information about the liquid distribution. This helps with diagnosing conditions such as fouled or crushed packing, liquid maldistribution as well as overflowing distributors and collector trays. Tracerco’s PackViewTM technology provides a quantitative measure of the liquid retention through the beds of packing and is an excellent tool to evaluate the quality of liquid phase distribution.
ThruVisionTM is the next step to investigate liquid maldistribution. In some cases, a Tru-GridTM Scan may appear to show no major problems, but symptoms of a problem persist. Tracerco’s advanced ThruVisionTM technique is a 360° scan, performed at a single elevation using multiple and overlapping positions, that produces a detailed contour map of the liquid distribution inside the tower. This detailed data can help identify a more complicated problem that may be proving difficult to identify using other techniques.
The use of Tru-GridTM Scan and ThruVisionTM technologies confirms the position and operating condition of packed beds and other major internals. This allows preparation of equipment and field services for any necessary repairs in advance, minimising downtime, emergency expenditures and lost production.
If you require any further information about packed bed towers, or any of our other cost-effective monitoring solutions, please do not hesitate to contact us.
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 troubleshooting column 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.
