Proactive Solutions in Visbreakers
The Visbreaking process obtains more valuable lighter hydrocarbons by thermally converting the heavier, less desirable residual oils. The process can produce a range of issues that need to be addressed, including foaming, corrosion, exchanger fouling, furnace coking and product instability. Dorf Ketal offers unique chemical programs to address these issues.
- Coking/fouling control in the heaters, while maintaining unit conversion rates
- Reduced deposition of asphaltenes and inorganic solids
- Stabilization of asphaltenic species in the visbroken tar product
- Reduced foaming
- Corrosion control in the fractionator overhead
