This book is intended primarily for regulatory officials, company administrators, engineers, technicians, industry maintenance personnel, and both undergraduate and first-year graduate students. It is assumed that the reader has taken basic courses in physics and chemistry; only a minimum background in mathematics is required (though calculus is desirable). The authors' aims are to offer the reader the fundamentals of HS&AM with appropriate practical applications in the chemical process industries and to provide an introduction to the specialized and reference books in this and related areas. The reader is encouraged to use the works cited in the bibliography to continue development beyond the scope of this book.
