- •
Residence time distributions of heavy residues were measured in pilot-scale soakers.
- •
Bromine-82 as dibromobiphenyl was used as radiotracer.
- •
Mean residence times were determined and flow patterns were quantified.
- •
Sectionalizing the visbreaker reduced the backmixing.
- •
Tanks-in-series with backmixing model was found suitable to describe flow.
