To learn process integration with regard to an efficient use of energy and enhance energy efficiency

Development of specific quantitative skills that will be useful in a wide range of processes in the design of inherently energy-efficient plants

The course contains the following deliverables:
1. Understand process integration and intensification
2. Find the minimum heating and cooling requirements for a process
3. Identify existing non-optimal arrangements of heat exchangers
4. Find lower cost solutions for arrangements of heat exchangers
5. Proficiency in energy efficient, environmentally benign and economic design of processes
