Xtend™ by XRG Technologies

The unique design of Xtend™ causes the flow to swirl inside the tube, increasing the amount of heat transferred. This generates more swirl with less pressure drop compared to a conventional twisted tape. The swirling flow: Cools the film on the tube wall Removes coke precursors from the film Increases temperature and product uniformity in the tube Xtend™ only needs to be installed in tubes that limit run length due to hot spots; this minimizes pressure drop while maximizing run length and cost savings. Xtend™ is removable. The unique design is sized so that it flexes with build-up and does not engage with coke layer. In coker unit simulations, Xtend™ reduces the tube wall temperature by as much as 33 °F. Lower film temperature and increased bulk flow uniformity result in up to 3x less coking in tubes equipped with Xtend™. Simulations show similar benefits for other services including crude, vacuum, and pyrolysis heaters. If one of these units causes a bottleneck, fixing a few problematic tubes could save millions.

  • Large crude heater revamp by XRG Technologies

    A large crude heater in The Netherlands suffered from reliability, fouling and capacity problems caused by flame impingement. In addition to eliminating this bottleneck, the client wanted to increase heater throughput by 29% and increase fuel efficiency to at least 90%.  XRG evaluated the system ...

  • Xceed™ by XRG Technologies

    Fired heaters in refineries and petrochemical plants emit millions of tons of CO2 & NOx every year. Lowering those emissions often causes flame quality issues which can reduce the coil life, run lengths, and capacity of your heater.

    Built on 30 years of research, XRG developed the Xceed ...
