How to use actionable insights to optimise trayed tower performance

Gas plants play a critical role in cleaning raw natural gas after being extracted from subterranean deposits.
This process isolates hydrocarbons, non-methane fluids, hydrates and impurities to produce dry pipeline quality gas, which is then transported to the end user. These plants are generally low maintenance compared to oil refineries and most chemical processing complexes. However, they have limited options in the event of disruptions, degrading conditions or incoming raw gas flows. If these conditions do arise, scanning technology has proven to be an effective screening tool for providing detailed information about the hydraulic performance of trayed towers.

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

Posted by Margaret Bletsch

Dec 20, 2017 3:15:04 PM

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.

How to define foam profiles in coke drums and verify level devices: A case study

Posted by Margaret Bletsch

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 Tracerco

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
