Emphasizing basic mass and energy balance principles, Chemical and Energy Process Engineering prepares the next generation of process engineers through an exemplary survey of energy process engineering, basic thermodynamics, and the analysis of energy efficiency. By emphasizing the laws of thermodynamics and the law of mass/matter conservation, the author builds a strong foundation for performing industrial process engineering calculations. The book’s systematic treatment applies these core principles on a macro-level scale, allowing for more manageable calculations.

The development of new processes is demanding and exciting. The instruction within these pages enables engineers to understand and analyze existing processes and primes them for participation in the development of new ones.
