Efficient cyclone systems for fine particle collection

Numerically optimised cyclones and recirculation systems have been shown to be highly efficient for the capture of fine particles, such as those occurring in the production of active pharmaceutical and food ingredients. Romualdo Salcedo and Júlio Paiva describe some of the recent developments in this area.

The optimised design of gas cyclones is of particular relevance for the recovery of highly valuable products, such as in the production of active pharmaceutical ingredients (API) through drying systems such as spray or fluid bed drying.
