Module summary

Chemical engineers have a crucial role to play in the defining how every day processes that are critical to the modern world impact on the environment and also the health of society. There are perhaps no processes more important than the production of drinking water and maintaining of clean air standards. This module will examine both air and water systems from a society and engineering view point, as key examples of environmental and health impact.Secondly, leaders and managers of any chemical or process engineering activity, be this in the private or public sector, need to make responsible, ethical decisions that protect the safety and health of an organisation's employees, users of the organisation's products and the wider public. Operating with a strong regard for safety and health protects not only people, but also the organisation's reputation and future. There can be a substantial, positive return on investment in safety and health, for example through avoiding productivity and property losses, impact on future insurance premiums, uninsured costs, fines etc. This module provides the tools and ways of thinking needed to address safety in the context of a chemical or process engineering organisation.

Objectives

Semester 1 of this module combines water treatment and air quality environmental health aspects. The key objectives for the water treatment section are to arm students with a knowledge of all the major unit operations involved with front end water treatment for domestic drinking purposes. It also includes a general assessment of the need for treatment, and international challenges to clean water, as well as the main types of organic and inorganic contaminants present. The air quality section highlights key air quality issues around the world, and includes analysis of monitoring data, in order to assess whether objectives in the National Air Quality Strategy have been met, and solutions for tackling these issues.

The process safety and health section of the module (in Semester 2) aims to equip students with the ways of thinking and tools needed to conduct chemical and process engineering activities in a safe manner that does not have negative impacts on health. This section of the module, therefore, focuses on the intersection of technology, people and processes but primarily exemplifies the methods used in industry to ensure process safety. The concepts covered in the module are illustrated by means of case studies.

Learning outcomes
Environment
- Be aware of specialist aspects of safety and environmental issues.
- Be aware of relevant legal requirements, codes or practice, and industry standards governing engineering activities.
- Have knowledge of the local legislative framework and how it is applied to the management of safety, health and environment in practice and in the workplace.
- Understand and be able to apply the principles of sustainability and the ability to apply techniques for analysing the interaction of process, product and plant with the environment and minimising adverse impacts.
- Understand basic chemical principles to characterize the performance of a range separation and similar processing steps for fluids and particulates in the context of water treatment.

Health and Safety
- Be able to identify the principal hazard sources in chemical and related processes.
- Be able to apply systematic methods for identifying process hazards (eg HAZOP), and for assessing the range of consequences.
- Understand the principles of safety and loss prevention, and their application to inherently safe design.
- Understand the principles of risk assessment and of safety management, and be able to apply techniques for the assessment and abatement of process and product hazards.
- Understand the security risks of digitalisation using process, cyber and automation.
