Decommissioning and the transportation of NORM and TENORM

Posted by Andrew Smith

Oct 3, 2018 9:56:48 AM

Underestimating the time and resource required to correctly transport NORM (Naturally Occurring Radioactive Material) or TENORM (Technologically Enhanced Naturally Occurring Radioactive Material) during decommissioning could prove to be costly, not least because it is likely to cause delays in shipping. It is clear that there are many considerations required to managing the transport of NORM and TENORM. Consultation with experts at the very early stages will be essential and could lead to significant cost saving benefits.

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.

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.

Decommissioning - To End or Extend?

Posted by Callum Grieves

Mar 27, 2018 9:04:10 AM

The challenging conditions faced in today’s oil and gas market has increased the focus on cost effective, sustainable operations. Operators are faced with the decision of extending or ending offshore production asset life and pre-decommissioning planning has emerged as a key challenge for the industry. Mitigating uncertainty, enabling decision making and justification as to whether to end or extend asset life, as well as detailed knowledge of asset conditions is crucial. In this blog, we will discuss how a range of Diagnostics services can be used to provide this detailed knowledge throughout late life operations.

Determine the Volume and Value of Material Lost To The Flare

Flare flow measurement is a crucial activity in chemical plants and refineries with loss of process material to the flare costing millions of dollars each year in profits and environmental costs. Tracerco Diagnostics™ Flow studies performed through sections of the flare piping system detect and isolate sources of fugitive flow. Once it is determined which unit(s) are contributing to the flare flow, each valve can be individually tested to determine which is leaking.

This blog will cover a customer case study illustrating how our Tracerco Diagnostics™ Flow studies played a key role in their predictive maintenance and process optimisation and a link to our Tracerco newsletter featuring two additional case studies on our flow study and meter proving services.

Active Personal Dosimetry in Industrial Radiography

Posted by Nick Hutchinson

Mar 13, 2018 8:29:12 AM

The International Atomic Energy Agency’s (IAEA) Specific Safety Guide No. SSG-11 which relates to Radiation Safety in Industrial Radiography states that radiography companies must ensure that employees (Category A Workers and potentially others who enter controlled areas) are subject to regular dose assessments in order to ensure that radiation doses are kept as low as reasonably achievable and dose limits are not exceeded. It is essential that reliable dose information is collected to ensure that the exposure of workers is properly controlled. Furthermore, dose assessments will also serve to highlight bad (and good) working practices. To meet this requirement, the employer will engage an Approved Dosimetry Service (ADS) so that they may provide suitable personal dosimeters together with a formal dose record keeping service.

Document liquid sulphur levels in a Sulphur Recovery Unit (SRU) Reactor during a catalyst wash.

Are you planning to “wash” a catalyst bed in a reactor and need to monitor process conditions?

Using Tru-Scan™ technology to detect liquid levels in pressure vessels and catalyst levels in reactors is a fast and extremely reliable measurement performed online. One of the problems operations staff faced when planning a catalyst “wash” was not having an indication of any accumulated liquid level in the bottom of the vessel to monitor the procedure. Read more on how Tracerco was able to assist a customer with monitoring the liquid level throughout their planned wash campaign.
