Abstract
Methods and apparatus for prilling are provided which include dynamically controlling the pressure at the prill head for increased control over prill quality and size distribution. In one embodiment, the pressure of a headspace above a volume of liquid or slurry is regulated to maintain a more precise control of the pressure of the liquid or slurry at the prill head. In another embodiment, an axial upflow device is used to maintain a more precise control of the pressure of the liquid or slurry at the prill head.
