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.

How to determine the best suited demulsifier for your application

Scans aid plant personnel in determining which demulsifier is best suited for their application.

Tracerco’s scanning technology is an excellent means of measuring interface levels, whether between vapour and liquids, liquid and solids, or between two different types of liquids. Tru-Scan™ and PhaseFinder™ neutron scanning technologies can be used very effectively in trials of emulsion breaking chemicals to determine the best type and concentration to use in a particular vessel. This can lead to increased efficiency and significant cost savings as well as reduce the environmental impact of excess chemical use.

This blog will present two demulsifier trials that will show the difference in performance base on the presence or absence of an emulsion layer.

Mar 3, 2017 3:24:45 PM

Tru-Scan™ is used by refineries to define foam profiles and verify level detection devices in their coke drums. A Tru-Scan can determine the difference in vapour density throughout a typical drum cycle.

In this latest blog, Tracerco, part of Johnson Matthey Plc, discusses how a Tru-Scan™ can be a powerful tool for gathering much needed information to optimise a coke drum cycle.

The top three questions we are asked about our tower scanning technology

Posted by Callum Grieves

Sep 29, 2016 10:01:29 AM


It is common in many oil refineries, chemical, ethanol and ammonia plants, for critical process equipment to experience problems. Issues in trayed towers such as internal tray damage, missing trays, plugged downcomers and tray foaming can all lead to off-spec production and in some cases, un-anticipated shutdowns. Scanning technology can help you avoid these scenarios by providing you with an assessment of your operating conditions, whilst your process equipment remains online. In this blog post we will feature the top three questions we are asked with regard to Trayed Towers and our Tru-Scan™ technology

How to minimise maintenance costs with exchanger leak testing: case study

Posted by Callum Grieves

Mar 15, 2016 10:30:36 AM

Detecting and identifying small leaks in heat exchangers can be an extremely difficult and time consuming task for many operators and plant personnel. Product quality, process efficiency and the time and cost associated with maintenance and potential shutdowns caused by a leaking vessel can have a significant and detrimental impact on production and process operating margins.

How to optimise the performance of your trayed columns: case study

Posted by Callum Grieves

Dec 9, 2015 10:12:34 AM

There are a number of problems that can cause a loss of efficiency and lead to loss of production in a distillation column, including tray damage, flooding, weeping, and foaming. Gamma scan technology available from Tracerco can be utilised to locate the origin and/or severity of these problems. A Tru-Scan™ across the active area of a fractionation tray can provide hydraulic conditions and/or mechanical status of the active area, such as weeping and tray froth heights. FrothView™, a new methodology developed by Tracerco, provides a quantitative analysis of tray capacity as the total froth height on a tray that is measured using Tracerco's new detector technology and software interpretation.

In this latest blog post we will discuss how a Tru-Scan™ and FrothView™ technology was used to provide the % tray space to show the amount or percentage of available tray spacing that is occupied by froth or aerated liquid. Knowledge of the actual process conditions inside a vessel, provides engineers with the ability to make process adjustments accordingly.

How to reduce operating costs and shutdown time of a distillation tower: case study

Posted by Nicola Porter

Sep 15, 2015 12:41:38 PM

Improving process operating margins can be achieved by maximising production of higher value products and/or minimising production costs. It is important for plant engineers to know how much capacity is available in the trays in a distillation tower.  Gamma scanning is an established method used by many in the process industries as a qualitative tool to help troubleshoot distillation towers. Gamma scanning can be used to diagnose virtually any operating malfunction that can be identified by an observable change in density. This includes most mechanical, process or rate related problems such as tray damage, foaming, weeping and entrainment. By deploying new measurement detector technology and incorporating innovative analysis of gamma scanning data, plant engineers can now acc ss the all-important quantitative data about the capacity of distillation towers.
