Abstract
Processes for continuously coalescing particles from an aggregated particle slurry are disclosed. An aggregated particle slurry is further heated in a first heat exchanger, and the heated slurry then flows through a residence time reactor. The slurry, now containing coalesced particles, then flows through a second heat exchanger and is quenched. The recovered coalesced particle slurry is then suitable for washing and drying. No moving parts are needed in this system.
