201 - Energy Balances Course Goals Energy is involved when a substance changes temperature, pressure, location, or phase, or when it reacts or forms a solution.
Energy is involved in all manufacturing processes.
Because of the First Law of Thermodynamics, all of the energy involved in a process can be accounted for, just like balancing a bank account. Providing and removing energy presents the chemical engineer with economic, safety, and environmental concerns as well as a technical challenge. The skills introduced in ChE 200 with matter will be reinforced and mastered here. Sketch a chemical process from a description, or describe a chemical process from a sketch. Identify parts of the process that involve the gain or loss of energy.
