prove the dissolution property and oral bioavailability of poorly water-soluble drugs, solid dispersion methods have been extensively used and numerous approaches have been reported such as fusion, solvent evaporation, and spray-drying methods. However, these methods involve various problems. Solid dispersions prepared by fusion usually have the shortcoming of being tacky and unstable, and solv...

Despite the wide-spread applications of spray drying in production chemicals, food, and pharmaceuticals, accurate control development this unit remains an elusive task because complex interactions variables phenomena. In paper, we offer a computationally efficient closed-loop system with model predictive controller (MPC) where computational fluid dynamics (CFD) process is utilized to represent ...

Removal of sludges from Wastewater Treatment Plants (WWTP) represents a serious worldwide environmental problem for which alternatives other than their simple incineration are investigated. In this work the treatment of raw sludge from urban WWTP by means of a minimization process through spray-drying is analyzed as well as some proposals for revaluating the resulting dry product. Analysis is s...
