ChE-408: Process intensification and green chemistry

The first part of the course (~20%) is devoted to green chemistry and life cycle assessment. The remainder focuses on process intensification (fundamentals, detailed description of a few selected technologies, with a special focus on microreactors). Exa ...

Description

This lecture introduces the principles and applications of green chemistry, focusing on the benefits and technologies of chemical process intensification. It covers topics such as green metrics, industrial examples, life cycle assessment, and process intensification technologies like membrane reactors and modular plants. The course also delves into the twelve principles of green chemistry and engineering, emphasizing the importance of renewable feedstocks and safe product design. Students will explore the environmental aspects of chemical processing, the evolution of world chemical sales, and the environmental/safety aspects of chemical synthesis.

Life-cycle assessment

Life cycle assessment or LCA (also known as life cycle analysis) is a methodology for assessing environmental impacts associated with all the stages of the life cycle of a commercial product, process, or service. For instance, in the case of a manufactured product, environmental impacts are assessed from raw material extraction and processing (cradle), through the product's manufacture, distribution and use, to the recycling or final disposal of the materials composing it (grave).

Sustainable design

Environmentally sustainable design (also called environmentally conscious design, eco-design, etc.) is the philosophy of designing physical objects, the built environment, and services to comply with the principles of ecological sustainability and also aimed at improving the health and comfort of occupants in a building. Sustainable design seeks to reduce negative impacts on the environment, the health and well-being of building occupants, thereby improving building performance.

Sustainability

Sustainability is a social goal for people to co-exist on Earth over a long time. Specific definitions of this term are disputed and have varied with literature, context, and time. Experts often describe sustainability as having three dimensions (or pillars): environmental, economic, and social, and many publications emphasize the environmental dimension. In everyday use, sustainability often focuses on countering major environmental problems, including climate change, loss of biodiversity, loss of ecosystem services, land degradation, and air and water pollution.

Sustainable development

Sustainable development is an organizing principle that aims to meet human development goals while also enabling natural systems to provide necessary natural resources and ecosystem services to humans. The desired result is a society where living conditions and resources meet human needs without undermining the planetary integrity and stability of the natural system. Sustainable development tries to find a balance between economic development, environmental protection, and social well-being.

Life cycle thinking

Life cycle thinking refers to the consideration of environmental impacts throughout the various stages of a product's existence and the endeavor to minimize these impacts whenever feasible. It aims to prevent the transfer of environmental burdens from one stage to another. Additionally, life cycle thinking acknowledges the role of technological advancement in addressing environmental concerns. This approach is adopted by companies in the development of eco-friendly products, by consumers in making conscious product selections, and by governments in establishing regulatory standards to mitigate environmental effects.
