Mass and Energy Balances

Mass and Energy Balances are what could be termed "The Chemical Engineer's bread and butter". Every problem that a Chemical Engineer encounters relies on a basic understanding of the concepts presented as mass and energy balances. The main concept from this topic is that "what goes in, must come out". Or in more professional terms, "In - Out + Generation - Accumulation = 0".
As for what is going in or coming out, that can be any number of things:

  • Raw Chemicals
  • Recycled streams from later in the process
  • Air
  • Water

This can also refer to lesser known items in the Chemical Engineers tool bucket

  • Heat
  • Enthalpy
  • Catalyst
  • Work
