The use of energy is fundamental in the process industry. Energy sources such as gas, oil, and coal are becoming increasingly costly, and also lead to environmental problems. Minimising the use of external heating and cooling sources and making the most efficient use of available energy is a cornerstone in the design of chemical processes.

This unit will briefly examine the various types of heat exchanger available to transfer heat between streams in chemical processes.

The unit will also evaluate opportunities to minimise and target energy use prior to the detailed design of the energy exchange (or heat exchanger) network. Such targets can be used to scope and screen many design options quickly and effectively without having to carry out the designs. Methodologies, including the well established Pinch Analysis, are developed and evaluated for both new design and retrofit (existing design) scenarios. Once design options have been chosen using targets (both energy and capital), then systematic procedures allow the targets to be achieved in practice. The external heating and cooling requirements of the chemical process can also be evaluated and included in this design.

Teaching Methods

The course makes use of traditional face-to-face lectures and problem solving sessions in the computer room. The course will also use flipped classroom and blended learning strategies. Students will watch online lectures, collaborate in online discussions, or carry out research at home.
All materials are available in the e-learning site. Communications outside of teaching slots also make use of tools such as MS teams.
You will be required to make use of engineering calculations and general problem solving skills, as well as simulation softwares.
Lectures will be mainly held in classrooms, and will be integrated with online teaching resources

Verification of learning

Referred to the objectives, test (3 h) to evaluate competence in process analysis and heat exchanger network design (simulation of a process, data analysis, HEN design)
