Introduction to Process Energy Analysis


This course focuses on analysis methods and strategies to design a minimum energy consumption process, including the evaluation of the thermodynamically lowest energy requirement of the process. Basics of pinch technology and heat exchanger network design will be reviewed. Examples will be provided to illustrate strategies for energy reduction via decreased utility consumption.

What can you learn?

  。The basic theory and applications of pinch analysis.

  。How to determine the utility consumption of plants and processes.

  。Why certain process modifications will reduce the energy consumption.

  。How to determine the true cost of steam and electricity.

  。What you should know about your plant when making fuel purchase contracts.

  。Tools to better evaluate projects for energy related capital expenditures.

  。How to identify mistakes in your operations that cost you money.

  。How to develop comprehensive energy reduction program for your company.
