Sommario/riassunto: | Stirring is one of the most important operations in process technology. No chemical exists that has non been submitted to a mixing process during its synthesis. Furthermore, stirring is important for the pharmaceutical and food industries, too.The most important mixing operations are applied to homogenize miscible liquids, to intensify the heat transfer between a liquid and the heat exchanger, and to perform mass transfer in multiphase systems, to whirl up solid particles in fluids and to disperse immiscible liquids.This book discusses in detail the above listed operations, tak |
