Chemical Engineering Principles

The purpose of this chapter is to gather in one place some of the basic considerations that apply to the engineering techniques and unit operations that are important in the chloralkali process. Thus, the chapter begins with a discussion of material and energy balances (Section 10.2). These are basic to all of chemical engineering and are used implicitly throughout this book. Here, we present some of the fundamentals. Section 10.3 then covers current distribution. This is uniquely important in electrochemical processing. The presentation discusses methods of predicting and determining the distribution of current in electrochemical reactors of different kinds.
