Solids Processing Fluidized-bed Solids Among the IPNF Topics
A series of talks at the International Powder and Nanotechnology Forum (IPNF) showcased several research projects on the behavior of solid materials in fluidized beds.
Stephen Heinrich, professor at Hamburg University, spoke about a hierarchical simulation approach to fluidized-bed spray-granulation processes. Heinrich’s multiscale simulation framework combines submodels at the microscale, mesoscale and macroscale to better understand the complex interconnections in granulation and agglomeration processes.
Osaka University Professor Takuya Tsuji presented research on simulating particle-drying processes in fluidized beds. Tsuji extended discrete-element-method simulations to take into account inter-particle, gas-particle, particle-wall and gas-wall heat transfer processes. Jun Oshitani, from Okayama University discussed the use of fluidized beds for dry-separation processes in waste treatment and mineral processing.
Aside from solids behavior in fluidized beds, the IPNF sessions at Achema also addressed several other solids-related topics. Among them was the use of atomic-force microscopy in evaluating the adhesion of particles to each other.
Other topics covered included antisolvent crystallization, crystallization at liquid-liquid interfaces and characterization of crystal shapes. The IPNF continued with talks on nanoparticle synthesis and characterization, microreactor technology and pharmaceutical co-crystals and drug delivery.
