# PROCESS AND ENERGY INTEGRATION - 2021/2

Module code: ENGM071

Module Overview

Process integration is an efficient tool, which enables the reduction of capital investment and energy consumption according to the principles of sustainable development applicable for new and retrofit process design. Computer-aided process engineering tools together with mathematical programming enable systematic and simultaneous handling of process integration problems.

This module introduces a wide range of methods of heat integration of processes within a production site and for total site energy integration. The design of heat exchanger networks (HEN), utility selection, integration of units such as heat engines, heat pumps, and placement of reactors and separators will be addressed. Sequential and simultaneous approaches will be explored utilizing graphical, empirical and mathematical modelling tools.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate

• Learning outcomes 1, 2, 3 in the unseen written examination;

• Learning outcomes 1, 2, a, b, c in Coursework 1;

• Learning outcomes 3, 4, a, b, c in Coursework 2.

Thus, the summative assessment for this module consists of:

• Unseen written examination, 2 hours;

• Coursework 1: Homework assignment, approx. 12 hours;

• Coursework 2: Design project with individual report, approx. 20 hours.

Formative assessment

• Class discussions

• Questioning

• Problem solving

Feedback

The students will receive written feedback on their coursework

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

Introduce graphical and mathematical methods of heat integration to students through lectures and working sessions. The methods are then applied in case studies identifying their advantages and disadvantages.

The learning and teaching methods include:

• 2 hours of lectures per week x 11 weeks;

• 1 hour working sessions per week x 11 weeks;

• 2 hours of supervised computer labs per week x 3 weeks.

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
