Advantages of PreTurnaround and Baseline Scans

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.Fouling_towers_web

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.

Packed bed performance analytics

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.

Tru-Grid™ Scans reveal vital process information that helps solve operating problems.
 
A Tru-Grid™ Scan of packed towers is a reliable and widely used field measurement used for evaluating the hydraulic performance in packed beds, including the results from plugging / fouling or damage. When experiencing problems there are two important questions you would like answered:
 
1. Where is the fouling / plugging or damage?  
2. What is the extent of the hydraulic problem due to fouling or damage to the packing?

Gamma scanning has proven to be an essential measurement tool to supplement operating history data analysis. Process engineers and operations personnel need to know what is happening inside their process equipment so they can take corrective action. A Tru-Grid™ Scan provides a density profile of the internal process to diagnose hydraulic operating conditions such as damage to internals, flooding, liquid levels on trays and distributors, and liquid distribution through packed beds.

Performing Tru-Grid™ Scans before a scheduled shutdown can help capture real-time data to optimize your turnaround and reduce cost over-runs. Scan results will prepare those planning the turnaround activities with the knowledge needed for critical path decisions. Scans performed five to six weeks prior to a scheduled shutdown usually provides enough time to order new equipment without expediting charges and to schedule the required manpower. 

In this latest blog, Tracerco, part of Johnson Matthey Plc, discusses how an unexpected pressure surge affected the performance of an acid solvent recovery column.
