Furnace fouling control

Furnace fouling control

Increases thermal conversion unit profitability by reducing heater tube fouling rates

  • Our furnace fouling control technology can be used to tackle the challenging issues that arise when you are trying to improve refinery profitability by:

    • Increasing thermal conversion unit throughput, where unit capacity is heater limited
    • Allowing unit to maintain maximum conversion, where heater outlet temperatures are reduced to maintain target throughputs or tube skin temperature limits during a run
    • Enabling upstream crude units to process higher rates of lower cost heavy crude oils
    • Decreasing coil de-coking costs
    • Reducing heater fuel consumption

    Our furnace fouling technology has significantly extended heater run lengths while reducing the frequency of coil decoking procedures

    Following a long-term research program to understand coker heater fouling mechanisms and how to control them, we developed specific fouling control treatment strategies for high severity applications such as visbreaker and coker heaters.  We can calculate and track the economic benefits provided through application of our furnace fouling technology using a proprietary heater fouling economic analysis software tool. 

    Customized treatment programs are designed using proprietary feedstock characterization and analysis methods. Feedstock properties are benchmarked versus our extensive database of characterization information developed for a wide range of thermal conversion unit feedstocks.

    Use of this proprietary characterization process and feedstock information database provides a better understanding of fouling mechanisms in a particular unit heater and helps determine the probable impact of candidate chemical solutions on heater fouling, which helps assure program success.

    Our fouling control additives have been developed to control heater fouling due to:

    • Thermal degradation of oils
    • Asphaltene destabilization
    • Catalytic effects of feed metals and equipment surfaces
    • Precipitation of organic and inorganic solids
