Are you planning a scheduled turnaround and want to know the advantages of scanning before and after your planned turnaround?
A Tru-Scan™ or Tru-Grid™ Scan will assist in defining and developing a turnaround critical path project scope at an early stage ensuring that your turnaround meets your goals. The most common use of gamma scans is to give process engineers and operations an online tool that results in understanding how a column is performing. This data can be used in advance of a turnaround to identify tray or packing damage and other process problems without having to shut down the column for internal inspections. These results will fully prepare turnaround planners with the knowledge they need for critical path decisions that must be made prior to a shutdown. At other times the results from a Tru-Scan™ or Tru-Grid™ Scan can either justify an unscheduled shutdown or identify options that will enable a plant to continue operating until the next scheduled shutdown.

Diagnose and take control of fouling issues.
In some processes a common problem that towers experience over a period of time is fouling of trays and packing with solid deposits. Fouling can cause conditions such as liquid maldistribution in packed columns or premature entrainment/flooding in trayed columns resulting in a loss of efficiency and an increase in operating pressure drop. Fouling may result from foreign material entering a column or from polymerization or decomposition occurring inside the column. The fouling may start under normal conditions or begin to build due to abnormal operating conditions.

Advanced analytics introduce a numerical and easily understood approach to tower gamma scanning
Refinery and chemical plant operations depend heavily on distillation and separation towers. Tower gamma scanning is well established in the process industries as a qualitative tool to help troubleshoot towers. Advances in data analysis have lead to a quantitative approach in expressing gamma scan data in numerical terms easily understood by process and operations engineers.
In a recent Tracerco article published by Petroleum Quarterly Technology (PTQ) magazine you will be able to read three example case studies of packed towers that will answer questions concerning the state of liquid distribution through the packed bed and illustrate how Tracerco's PackView™ analysis was developed to consistently analyse Tru-Grid™ Scan data to reach a conclusive result.
