With worked examples on biochemical, electrochemical, environmental, physico-chemical and thermochemical processes. What you need to know to calculate the distribution of material and energy in industrial and natural processes.

“Ol’s Notes on Material and Energy Balances” is a compact and inexpensive resource for teaching the basics of chemical and biological engineering at the 1st and 2nd year university level.

Based on the author’s 20 years experience as an instructor of material and energy (M&E) balances and related topics (www.chml.ubc.ca) “Ol’s Notes” presents the calculation of M&E balances as a powerful tool in accounting for the distribution of material and energy in chemical* processes. Assuming a background in high-school science and mathematics the “Notes” treat M&E balances in a user-friendly, efficient and transparent format, hinging on the general balance equation, combined with the function of six generic process units: divider, mixer, separator, heat exchanger, pump and reactor. 

The worked examples illustrate the principles of each chapter and range from simple computations to relatively complex modeling of multi-unit recycle and unsteady-state processes. The calculations focus on SI units, and are directed to the use of computer spreadsheets, with itemized flowsheets and stream tables to represent practical systems.  Although the examples are mainly concerned with chemical engineering many are angled at environmental problems that show the relevance of material and energy balances to the sustainability of life on Earth.

The text is sprinkled with cartoons that help to focus attention on important concepts. 

*“Chemical” means biochemical, electrochemical, environmental, photochemical,
 physico-chemical and thermochemical.
