Development of a Pedagogical Model to Help Engineering Faculty Design Interdisciplinary Curricula
International Journal of Teaching and Learning in Higher Education 2016, Volume 28, Number 3, 372-384 http://www.isetl.org/ijtlhe/ ISSN 1812-9129 Development of a Pedagogical Model to Help Engineering Faculty Design Interdisciplinary Curricula Maria Navarro, Timothy Foutz, Kerri Patrick Singer and Sidney Thompson Ray International Group University of Georgia The purpose of this study was to develop a model to help engineering faculty overcome the challenges they face when asked to design and implement interdisciplinary curricula. Researchers at a U.S. University worked with an Interdisciplinary Consultant Team and prepared a steering document with Guiding Principles and Essential Elements for the design, implementation, and evaluation of integrative curricula in engineering education. The team also developed exemplar materials (Integrative Learning Module) to provide a practical example and demonstrate how the tools provided could be used in the development of new curricula. The Guiding Principles, Essential Elements, and Integrative Learning Module were evaluated by faculty and students who provided feedback for their improvement. Faculty indicated that the tools provided were appropriate guidelines for faculty, but they indicated that the Integrative Learning Module was too long to be a manageable example. Students agreed about the need for more interactive, real-world applications of engineering concepts, but they expressed differences of opinion regarding how humanities and social sciences topics should be addressed in the engineering curriculum. Students who participated in a course modeling the Integrative Learning Module were satisfied with its use and learning outcomes. After the course, these students were able to explain the importance of problem definition, process, and disciplinary integration in engineering work. -
Chemical Engineering Careers in the Bioeconomy
BioFutures Chemical engineering careers in the bioeconomy A selection of career profiles Foreword In December 2018, IChemE published the final report of its BioFutures Programme.1 The report recognised the need for chemical engineers to have a greater diversity of knowledge and skills and to be able to apply these to the grand challenges facing society, as recognised by the UN Sustainable Development Goals2 and the NAE Grand Challenges for Engineering.3 These include the rapid development of the bioeconomy, pressure to reduce greenhouse gas emissions, and an increased emphasis on responsible and sustainable production. One of the recommendations from the BioFutures report prioritised by IChemE’s Board of Trustees was for IChemE to produce and promote new career profiles to showcase the roles of chemical engineers in the bioeconomy, in order to raise awareness of their contribution. It gives me great pleasure to present this collection of careers profiles submitted by members of the chemical engineering community. Each one of these career profiles demonstrates the impact made by chemical engineers across the breadth of the bioeconomy, including water, energy, food, manufacturing, and health and wellbeing. In 2006, the Organisation for Economic Co-operation and Development (OECD) defined the bioeconomy as “the aggregate set of economic operations in a society that uses the latent value incumbent in biological products and processes to capture new growth and welfare benefits for citizens and nations”.4 This definition includes the use of biological feedstocks and/or processes which involve biotechnology to generate economic outputs. The output in terms of products and services may be in the form of chemicals, food, pharmaceuticals, materials or energy. -

Introduction to Separation Processes What Is Separation and Separation Processes ?
Introduction to Separation Processes What is Separation and Separation Processes ? • Separate (definition from a dictionary) - to isolate from a mixture; [extract] - to divide into constituent parts • Separation process - In chemistry and chemical engineering, a separation process is used to transform a mixture of substances into two or more distinct products. - The specific separation design may vary depending on what chemicals are being separated, but the basic design principles for a given separation method are always the same. Separations • Separations includes – Enrichment - Concentration – Purification - Refining – Isolation • Separations are important to chemist & chemical engineers – Chemist: analytical separation methods, small-scale preparative separation techniques – Chemical engineers: economical, large scale separation methods Why Separation Processes are Important ? • Almost every element or compound is found naturally in an impure state such as a mixture of two or more substances. Many times the need to separate it into its individual components arises. • A typical chemical plant is a chemical reactor surrounded by separators. Separators Products Reactor Separator Raw materials Separation and purification By-products • Chemical plants commonly have 50-90% of their capital invested in separation equipments. Why Separation is Difficult to Occur? • Second law of thermodynamics - Substances are tend to mix together naturally and spontaneously - All natural processes take place to increase the entropy, or randomness, of the universe -
7 Secrets to a Well-Run Plant a Guide for Plant Managers and Operations Staff
WHITE PAPER Making Confident Decisions in Operations: 7 Secrets to a Well-Run Plant A Guide for Plant Managers and Operations Staff Terumi Okano, Aspen Technology, Inc. Have you ever received a call in the middle of the night because of a plant operational crisis? The production engineer responsible for the process is already onsite but they really need your advice and will likely also need support from the process engineering team. You can almost see the lost revenue growing as the plant drifts further from its Key Performance Indicators (KPIs). Detailed simulation models are likely already used by the process engineering or modeling team who support your plant in solving these kinds of complex process issues. Your production engineers certainly don’t have the time to learn new software to build detailed models. What you may not know is that sophisticated modeling technology can be accessed by your team through an easy-to- use, Microsoft Excel® interface. Model-based decision-making can apply to plants of nearly every type ranging from ethylene to polymers, fertilizers and specialty chemicals. The following seven secrets explain how building a model-based culture in your plant will bring clarity and continuous improvements to plant operations. Secret #1: Conceptual design models can assist plant operations. Do you know how or where the design work was done for your chemical plant? If you are able to find the conceptual design work that was completed with process simulation software, you’re already one step ahead. If it’s been decades since the plant was built and there is no design work 1to be found, start with asking for simulation models of problematic pieces of equipment or a section of your process that can be unreliable.
