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.

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

Tru-Scan™ and Tru-Grid™ scans are powerful tools that give you valuable insights into packed and trayed towers, tanks, pipes and more. Using this field-proven predictive maintenance technique on distillation columns allows plant personnel to monitor tray or packing hydraulics. A sophisticated monitoring programme can track the effects of fouling or other incapacitating conditions to extend run times and identify maintenance requirements in advance of scheduled turnarounds.
