PROCESS AND ENERGY INTEGRATION - 2023/4

Module Overview

Process integration is an efficient paradigm, 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 equips students with the knowledge and skills required to maximise the energy efficiency of existing and new industrial processes while improving process economics and minimising its environmental impact. It 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. Students will also continue to develop their problem-solving skills and digital capabilities by using state-of-the-art process simulation software.

• Class discussions


• Questioning


• Problem solving

Module aims

• - Develop the students' understanding of the area of process integration.

  - Develop an understanding of the main approaches to the solution of heat integration problems in process design and available software tools.

Learning outcomes

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:

• captured content


• lectures


• tutorials


• supervised computer labs


• independent learning

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.

Other information

This module contributes to the student development in the following ways aligned with the five pillars of the Surrey Curriculum Framework:
Digital capabilities: students will be developing their general IT skills by engaging with SurreyLearn and other electronic resources provided to them. They will also learn how to use state-of-the-art process simulation software (Aspen Plus) which is widely used in industry. Students will also be encouraged to use additional software tools such as MS Excel and GAMS to solve heat integration problems.
Employability: the module provides students with knowledge and skills on how to maximise energy efficiency in new and retrofit industrial processes. These are of critical importance for improving process economics as well as reducing green house gas emissions. These skills and understanding the wider context of the knowledge acquired in the module will improve the students’ competitiveness in the job market.
Global and cultural capabilities: the module content is presented in the context of the global challenges, in particular, climate change caused by human activity, which helps students to become well-rounded professionals.
Resourcefulness and resilience: the tutorial problems and coursework assignments are designed to challenge students and develop their reasoning and problem-solving skills, which requires consistent effort throughout the semester and develops their resilience.
Sustainability: this module has sustainability at its core due to the focus on improving energy efficiency of industrial processes. This leads to the development of ‘greener’ processes due to the reduction of associated greenhouse gas emissions and more sustainable production.
