Fast Liquid-phase Processes In Turbulent Flows

Various processes in which reagents in consequence of interaction undergo deep conversions followed by changing of internal structure, substances composition and aggregate state are realized in chemistry and applied chemistry. Chemical-engineering processes use to contain the physical ones also, in particular liquids movement, their mixing, heating and cooling, dispersion, etc. It is worth saying that technology of various chemical products production as a rule comprises chemical and physical processes of the same type characterized by common regularities. But for all that processes of different productions are carried out in apparatus of analogous principles of operation. According to the classification of applying chemistry apparatus there are only two theoretical (limit) models of instruments: apparatus of ideal displacement and of ideal mixing. Real ever-functioning reactors are representing apparatus of intermediate type with some approximation to apparatus of mixing or displacement. It is because particles residence time in them distributes more uniformly than in ideal displacement apparatus but never becomes level as in ideal mixing apparatus. Annotation This book deals with the fundamental laws of passing of fast liquid-phase chemical as well as heat and mass transfer processes in turbulent flows. The fundamental laws of passing of fast liquid-phase chemical and also heat and mass transfer processes in turbulent flows are considered in the book. Development of a macrokinetics approach is generalized to the analysis of fast chemical reactions mainly based on an example of cationic isobutylene polymerization, which falls into to a new class of liquid-phase processes. The ways of decision of the hydrodynamical, thermal and kinetic movement's equations of reaction mixture in which the fast exothermic chemical reaction runs are described. The principles and laws of formation of the essentially new mode of quasi-plug-flow mode are considered in turbulent flows ensuring quasi-isothermal conditions in zone reaction. The principles of work and area of industrial use of tubular turbulent devices cylindrical reactor, divergent-covergent reactor, shell-and-tube reactor, and reactor with fractional introduction of reactants are considered
