Description

An innovative approach that helps students move from the classroom to professional practice

This text offers a comprehensive, unified methodology to analyze and design chemical reactors, using a reaction-based design formulation rather than the common species-based design formulation. The book's acclaimed approach addresses the weaknesses of current pedagogy by giving readers the knowledge and tools needed to address the technical challenges they will face in practice.

Principles of Chemical Reactor Analysis and Design prepares readers to design and operate real chemical reactors and to troubleshoot any technical problems that may arise. The text's unified methodology is applicable to both single and multiple chemical reactions, to all reactor configurations, and to all forms of rate expression. This text also . . .

  • Describes reactor operations in terms of dimensionless design equations, generating dimensionless operating curves that depict the progress of individual chemical reactions, the composition of species, and the temperature.
  • Combines all parameters that affect heat transfer into a single dimensionless number that can be estimated a priori.

  • Accounts for all variations in the heat capacity of the reacting fluid.

  • Develops a complete framework for economic-based optimization of reactor operations.

Problems at the end of each chapter are categorized by their level of difficulty from one to four, giving readers the opportunity to test and develop their skills.

Graduate and advanced undergraduate chemical engineering students will find that this text's unified approach better prepares them for professional practice by teaching them the actual skills needed to design and analyze chemical reactors.

Index.

  • A unified, systematic, generic approach to design chemical reactors with multiple reactions.
  • Capability to formulate the design of any reactor configuration with any number of chemical reactions having any stoichiometry and any form of rate expression.
  • Reactor operations are described by dimensionless variables (in most cases, between -1 and 1) and dimensionless design equations.
  • The design is formulated in terms of the smallest number of design equations and the least number of terms in each equation; hence, the most robust formulation.
  • Solutions of the design equations provide dimensionless operating curves (a new concept in CRE).
  • These curves provide complete information on the progress of the chemical reactions, the formation (or depletion) of all individual species, and changes in temperature (see example on next page). Reactor sizing represents a "point" on these curves (similar to the way a "point" on dimensionless friction factor versus Reynolds number charts is used).
  • New design capabilities for reactor configurations whose design equations are not available in the literature (semi-batch reactor, filling reactor, plug-flow reactor with distributed feed, distillation reactor, etc.).
  • A framework for new economic-based optimization tools for chemical reactor operations, and for analyzing integrated chemical processes.
