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.

This book describes the fundamentals of fast liquid-phase chemical reactions and the principles of their scientific foundation, technical implementation and industrial application of new technologies. In addition, the equipment required to perform these reactions, in a turbulent mode in the chemical, petrochemical and petroleum industries, is also discussed. The macrokinetic approach has been developed with consideration of the diffusion, hydrodynamics, and heat transfer processes. Due to the advancement of fundamental knowledge, equations of practical engineering importance have been obtained for the calculations of mass and heat transfer processes carried out in conditions of high turbulence, and developed for the implementation in fast chemical reactions involving the synthesis of low molecular weight products and polymers. New methods for controlling the molecular characteristics of polymers have been developed based on the tailored regulation of the hydrodynamics of the reactive mixture flow. Typical processes have been used as model examples to reveal the influence of turbulence on the behaviour of fast chemical reactions used for the synthesis of low molecular weight products, in single-phase and two-phase reactive systems. Brand new tubular devices have been developed with the following characteristics: compact size, high productivity, and a quasi-perfect mixing operation mode in turbulent flows. These devices are subdivided into cylindrical, shell-and-tube, 'zone', and diffuser-confusor designs. Original solutions are proposed for the instrumental implementation of fast liquid-phase processes and development of continuous energy- and resource-efficient technologies for the synthesis of some large-scale compounds.

Fast Polymerization Processes presents fundamental results of investigation in the field of fast polymerization processes. A practical approach to the studying and modeling of polymerization processes is highlighted, taking into consideration the influence of such issues as the reactants' concentration, flow velocities, densities, heat conductivities, and hydrodynamics parameters. Particular attention is devoted to an in-depth description of previously unknown rules which are characteristic of fast polymerization processes.

This book contains papers presented at the 11th Symposium of Computer Aided Process Engineering (ESCAPE-11), held in Kolding, Denmark, from May 27-30, 2001. The objective of ESCAPE-11 is to highlight the use of computers and information technology tools, that is, the traditional CAPE topics as well as the new CAPE topics of current and future interests.The main theme for ESCAPE-11 is process and tools integration with emphasis on hybrid processing, cleaner and efficient technologies (process integration), computer aided systems for modelling, design, synthesis, control (tools integration) and industrial case studies (application of integrated strategies). The papers are arranged in terms of the following themes: computer aided control/operations, computer aided manufacturing, process and tools integration, and new frontiers in CAPE. A total of 188 papers, consisting of 5 keynote and 183 contributed papers are included in this book.

The main goal of this book is to describe the synthesis and properties of low and high-molecular compounds on the quantitative level. Special attention was given to composition materials based on polymers and dispersed wood, the mechanism of HCL elimination reactions via a four-centre transition state during PVC thermal destruction, swelling of the filled polymer compositions, structure and properties of combined systems based on butadiene-nitrile and ternary ethylene-propylene elastomers, intensification mass transfer processes in fast liquid-phase chemical reactions, the examples of hetero-nanophase kinetic description of photochemical reactions, the nanometric particle-like local structures and their implications in polymer behaviour, fractal physical chemistry of polymer solutions, modification of polycyanurates by polyethers, polyesters and polyurethanes, hybrid and interpenetrating polymer networks. This collection includes articles devoted to production of polymers, polymeric mixtures, composite and filled polymers, questions of expanding lifetime of polymeric articles, biologically active substances, modification of polymers and polymer-analogous transformations, fractal physical chemistry of polymer solutions, the study of structural transformations in polymers and some other questions. Of special attention are also production of pure substances and protection of the environment.

Polymer material science is the science of polymer materials creation, their processing, preservation and control of their operation properties. Ageing and stabilisation of polymers, as well as combustibility of polymeric materials, are broad sections of polymer material science. This collection presents articles not only on polymers, but also on some low-molecular compounds (and their reactivity), which are important for production of polymeric articles.
