Mole balances industrial reactors

From this general mole balance equation we can develop the design equations for the various types of industrial reactors batch, semibatch, and continuous-flow. Upon, evaluation of these equations we cau determine the time (batch) or reactor volume (continuous-flow) necessary to convert a specified amount of the reactants to products. 

The first chapter focused on the general mole balance equation die balance was applied to the four most common types of industrial reactors, and a design equation was developed for each reactor type. In Chapter 2 we first define con-version and then rewrite the design equations in terms of conversion. After car rying out this operation, we show how one may size a reactor i.e., determine the reactor volume necessary to achieve a specified conversion) once the relationship between reaction rate, r, and conversion is known. 

Overview—Chapter 1, This chapter develops the first building block of chemical reaction engineering, mole balances, that will be used continually throughout the text. After completing this chapter the reader will be able to describe and define the rate of reaction, derive the general mole balance equation, and apply the genera mole balance equation to the four most common types of industrial reactors. 

We call Equation (2-6) the dit ferential form of the design equation for batch reactor because we have written the mole balance in terms of converstor The difTereniial forms of the batch reactor mole balances. Equations (2-5) ani (2-6). are often used in the interpretation of reaction rate data (Chapter 5) atu for reactors with heat effects (Chapter 9), respectively. Batch reactors are fre qiiently used in industry for both gas-phase and liquid-phase reactions. Thi laboratory bomb calorimeter reactor is widely used for obtaining reaction raa data (see Section 9.3). Liquid-phase reactions are frequently carried out it batch reactors when small-scale production is desired or operating diflicultie rule out the use of continuous (low. systems.

Overview. In the hrst chapter, the general mole balance equation was derived and then applied to the four most commcm types of industrial reactors. A balance equation was deveicqred fcM each reactor type and these equations are summarized in Table 1 in Chapter L In Chapter 2, we will show how to size and arrange these reactors conceptually, so that the reader may see the structure of CRE design and will not get lost in the mathematical details.
