Book Description
Fixed-Bed Reactor Design and Diagnostics: Gas-Phase Reactions presents the essential theoretical and conceptual background of gaseous reactions catalyzed by solid catalysts in fixed beds. This book intends to provide recommendations to professionals who seek for modeling, scale-up, and diagnostics of fixed-bed reactors. The text is divided into three parts. Part I provides the conceptual background and relevant theories. Part II presents recommended mathematical models, scale-up procedures, and diagnostic methods. Part III gives a number of practical examples. The topics that are specifically discussed include heterogeneous catalysis and kinetics; general tubular reactor model; and general diagnostics for fixed-bed reactors. Engineers and professionals working with fixed-bed reactors will find the book highly informative.

Book Description
Practical Guides in Chemical Engineering are a cluster of short texts that each provides a focused introductory view on a single subject. The full library spans the main topics in the chemical process industries that engineering professionals require a basic understanding of. They are ‘pocket publications’ that professional engineers can easily carry with them or access electronically while working. Each text is highly practical and applied, and presents first principles for engineers who need to get up to speed in a new area fast. The focused facts provided in each guide will help you converse with experts in the field, attempt your own initial troubleshooting, check calculations, and solve rudimentary problems. Adiabatic Fixed-bed Reactors covers the fundamentals of fixed-bed reactors, including various types and their physical properties. Applications of each device type are discussed, as well as trouble-shooting Solid-supported Catalysts. This text is ideal for any engineer who is new to working with fixed-bed reactors and needs to know the basics quickly and easily. Practical, short, concise information on the basics will help you get an answer or teach yourself a new topic quickly Supported by industry examples to help you solve a real world problem Single subject volumes provide key facts for professionals

Book Description
This book provides a hybrid methodology for engineering of trickle bed reactors by integrating conventional reaction engineering models with state-of-the-art computational flow models. The content may be used in several ways and at various stages in the engineering process: it may be used as a basic resource for making appropriate reactor engineering decisions in practice; as study material for a course on reactor design, operation, or optimization of trickle bed reactors; or in solving practical reactor engineering problems. The authors assume some background knowledge of reactor engineering and numerical techniques. Facilitates development of high fidelity models for industrial applications Facilitates selection and application of appropriate models Guides development and application of computational models to trickle beds

Book Description
Chemical Engineering and Chemical Process Technology is a theme component of Encyclopedia of Chemical Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty Encyclopedias. Chemical engineering is a branch of engineering, dealing with processes in which materials undergo changes in their physical or chemical state. These changes may concern size, energy content, composition and/or other application properties. Chemical engineering deals with many processes belonging to chemical industry or related industries (petrochemical, metallurgical, food, pharmaceutical, fine chemicals, coatings and colors, renewable raw materials, biotechnological, etc.), and finds application in manufacturing of such products as acids, alkalis, salts, fuels, fertilizers, crop protection agents, ceramics, glass, paper, colors, dyestuffs, plastics, cosmetics, vitamins and many others. It also plays significant role in environmental protection, biotechnology, nanotechnology, energy production and sustainable economical development. The Theme on Chemical Engineering and Chemical Process Technology deals, in five volumes and covers several topics such as: Fundamentals of Chemical Engineering; Unit Operations – Fluids; Unit Operations – Solids; Chemical Reaction Engineering; Process Development, Modeling, Optimization and Control; Process Management; The Future of Chemical Engineering; Chemical Engineering Education; Main Products, which are then expanded into multiple subtopics, each as a chapter. These five volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.

Book Description
Various aspects of the behaviour of fixed bed reactors supporting highly exothermic reactions, relevant to stable -optimal design and control, have been studied using detailed mathematical models. In order to establish the form of the simplest basic structure, two methods of describing radial heat transfer in two dimensional packed beds have been examined. It is shown that a lumped parameter single phase heat transfer model which implicitly incorporates the heterogeneous structure can account not only for the radial heat flux associated with both the fluid and solid phases but is also the more appropriate formulation since it allows the important reaction rate limitations due to intraparticle mass transfer to be properly estimated. Using this two dimensional, heterogeneous dynamic model of the reactor it has been possible to evaluate a simpler one dimensional formulation. It is shown that the latter gives an adequate-description of the dynamic behaviour of the system, provided that the overall heat transfer coefficient between the fluid and the coolant is suitably defined, and may, therefore, be used for general studies of reactor performance. Consideration has been-given to the response of the reactor to sinusoidal perturbations of the inlet conditions. It has been found that at certain frequencies of oscillation temperature runaway may develop before a safe quasi-stationary state is reached. A detailed examination of this behaviour has shown that in addition to the non-linear effects the difference in the speeds of propagation of the concentration and temperature waves along the reactor as a result of the heterogeneity of the system is also very significant. The effect of both cocurrent and countercurrent cooling of a single reactor tube has been examined. The behaviour for perturbations in coolant temperature is similar to that for inlet temperature and indicates potential difficulties in the design of control systems. A mathematical model of a multitubular reactor with crossflow cooling has been developed and used to identify some of the problems which may arise in these systems. In particular, considerable interaction between the individual reactor tubes occurs when significant conversion of the reactant takes place. This causes tubes in different parts of the bundle to exhibit different behaviour and with countercurrent cooling this may give rise to multiple steady states due to the feedback of heat within the system. A technique has been developed for predicting regions of parametric sensitivity and temperature runaway in heterogeneous fixed bed reactors. The relationship between this form of instability and that due to multiple states of the catalyst pellet has been demonstrated. Application of this method to both the design and control of a reactor is discussed and it is shown that it provides an insight as to the behaviour of the system since it makes possible the establishment of a relationship between local and global reactor stability and the operating variables.
