Principles of Chemical Engineering

Energy Laws Several laws have been proposed to relate size reduction to a single variable, the energy input to the mill. These laws are encompassed in a general differential equation (Walker, Lewis, McAdams, and Gilliland, Principles of Chemical Engineering, 3d ed., McGraw-HiU, New York, 1937) ... 

Instruments favoring the standardization of chemical engineering curricula quickly multipled after 1921. First of all, a textbook based on unit operations was needed. Principles of Chemical Engineering written by W. H. Walker, W. K. Lewis, and W. H. McAdams appeared in 1923. Two years later, the first list of accredited institutions was drawn up, and its impact must have been rather great since its main characteristic was strict selectivity. Only fourteen universities shared the honor of appearing in the select list of AIChE. This policy was not a...

In the following pages we shall see that reactor design involves all the basic principles of chemical engineering with the addition of chemical kinetics. Mass transfer, heat transfer and fluid flow are all concerned and complications arise when, as so often is the case, interaction occurs between these transfer processes and the reaction itself. In designing a reactor it is essential to weigh up all the... 

The cocoa and chocolate consumed by the American market are produced by a relatively small number of American and Dutch manufacturers who start with the dried, fermented beans. Current manufacturing practice uses improved machine design and extended automatic control in accord with modern principles of chemical engineering, but it is based solidly on the traditional process, little modified during the last century.

Thanks to the leadership of Lewis and his colleagues, the chemical engineering department became an intellectually powerful center during this period. Its preeminence was fostered by the publication of the pioneer text in 1923, Principles of Chemical Engineering, by Walker, Lewis, and William H. McAdams. At the same time, Lewis developed a new kind of relation with industry, one that proved to have enormous impact on the chemical process industries and on teaching and research in academia. In fact, petroleum refining was the industry that provided the key to many future developments in chemical engineering.
