Improved Visbreaker and Coker Performance for Better Yields
Making the most of feedstock can offer cost and environmental advantages to refinery operators. When used before the visbreaking or coker process, Cavitech™ heads—placed in the feedline before heating—provide the following benefits:
- Increased conversion of light components
- Reduced visbreaker residuum viscosity
- Reduced cutter consumption
