A virtual lab as a complement to traditional hands-on labs: Characterization of an alkaline electrolyzer for hydrogen production
Publication date: Available online 27 March 2018 Source:Education for Chemical Engineers Author(s): J.C. Domínguez, R. Miranda, E.J. González, M. Oliet, M.V. Alonso Laboratories are commonly included as part of university courses as a way to relate theoretical lectures with experimental processes. In this sense, an excellent tool widely employed in academic teaching is the use of simulation software as a link between theory and traditional hands-on practice. This work is focused on the use of a virtual lab, i.e., a simulation, to study the electrolysis of water for hydrogen production, as a complement to tradition...

Sieving the class: Teaching particle size distributions and analysis
Publication date: Available online 23 March 2018 Source:Education for Chemical Engineers Author(s): Colin Brown, Clive Davies, Nicola Brown, Tony Paterson Some engineering subjects, while mathematically straightforward, can be conceptually difficult for students to understand. Traditional lecture methods using textbooks and PowerPoint point slides, while popular with some lecturers, are not always the best teaching tool when critical concepts require embedding. In this paper we consider the development of a simple exercise to introduce and teach principles of particle size analysis. A practical exercise we have terme...

Gamestorming for the Conceptual Design of Products and Processes in the context of engineering education
Publication date: Available online 11 November 2017 Source:Education for Chemical Engineers Author(s): G. Feijoo, R.M. Crujeiras, M.T. Moreira Creating an ideal environment to develop creativity and innovation in engineering education is a real challenge. One alternative approach can be based in the application of Gamestorming methodology that considers the use of games in the process of brainstorming. Presenting the problem in a game format eludes the conventional lecturing and frees the participants to think creatively to solve problems. In this contribution, the adaptation of the Gamestorming methodology was applie...

Graphic web –apps for teaching ternary diagrams and liquid–liquid extraction
Publication date: Available online 14 November 2017 Source:Education for Chemical Engineers Author(s): Tamás Bánsági, Thomas L. Rodgers Recent years have seen a rapid development in e-learning technologies. Specific topics; however, may require additional teaching tools created particularly for their unique characteristics. It is important that these tools are developed with learning outcomes in mind, and if possible are in a format easily accessible. We have developed graphic web applications for the teaching of liquid–liquid equilibria, single- and multi-stage liquid–liquid extraction using ternary phase diagr...

Development of operator training simulator for isopropyl alcohol producing plant
In this study, an operator training simulator was developed for an isopropyl-alcohol producing plant. The main product of this plant is isopropyl alcohol — water azeotrope, by-product is diisopropyl ether which are formed by direct hydrolyzation of propylene via strong acid cation exchange resins. Firstly, the steady-state simulator of the plant was developed. The next step was to develop the dynamic simulator and the control system of the process. Reference data – main parameters of the equipments and streams – for this simulator was provided by the stationary simulator. The simulator contains the preheater and the ...
