Mass & Energy Balances

Mass and energy balances are the bookkeeping fundamentals of chemical engineering: every atom in must equal every atom out, and every joule must be accounted for across each unit operation. Engineers use balances to size equipment, verify operating data, troubleshoot losses, and assess process efficiency and emissions. Mastery of balances is the prerequisite for nearly every downstream skill in refining and chemical processing, from process design to advanced control to sustainability reporting.
