The active learning integrative approach of simulation-based exercises along with the core course would help undergraduate students with more engaged learning. The present study describes the simulation approach using an open-source process simulator with the help of three simulation-based exercises. The first one exemplifies the importance of the selection of an appropriate fluid package. The second exercise presented in the study shows the effect of using optimized and default values of binary interaction parameters on VLE prediction of alcohol-ester systems. The small interactive simulation-based problems with expected outcomes were presented in the third exercise which makes the learning more engaging and interesting. The current study highlights an integrative approach to inculcating critical thinking and self-learning abilities using small simulation-based exercises while learning chemical engineering thermodynamics. Finally, a survey with closed- and open-ended questions was used to gather the opinions of students on the presented exercises. A short communication is needed that sheds light on the integrative approach of learning process simulation complementing the thermodynamic theory learning.

This critique discusses the Excel spreadsheet developed by Gómez-Siurana and Font-Escamilla for the application of relaxation methods to solve a simple multicomponent distillation column.

The level of safety and efficiency of technological processes operation largely depends on the qualifications of operating personnel. In continuous processes of such industries as chemical, mining, processing, energy, etc., it is common practice to use computer simulators to master the skills of making the right decisions in emergency conditions or ability to choose an efficient mode of operation. With the aim of controlling the safety level of work, it is required to have an opportunity to evaluate the efficiency of methods and learning outcomes. There is no single approach to learning outcomes using simulator trainings at energy-providing enterprises with continuous and technological processes. The main task of such enterprises is to train students with a set of knowledge and skills that will ensure the required level of safety and operational efficiency. This research proposes the technique for training, which includes the sequence of theoretical and practical exercises, metrics for automatic recording of students’ actions and criteria for assessing training efficiency. The authors have tested the proposed sequence of theoretical and practical exercises on the simulator on groups of engineering students. The results of the students’ execution of practical tasks on the simulator have been recorded using the proposed metrics. Based on the results the authors have proposed the criteria to assess students’ understanding of cause-and-effect relationships. The learning outcomes according to the technique and the proposed criteria have been verified with the help of blind test and the implementation of the final practical task on the simulator. The technique has been tested on different groups of students and it is obvious that due to the proposed metrics instructors are able to track the progress of learning. The research results can be applied at plants with continuous technological processes or in higher educational institutions. This practice-based approach to training can help to build the required set of knowledge and skills, which, in turn, will enhance the level of safety and operational efficiency. The engineering universities and enterprises of industry are currently implementing the proposed technique and computer simulator and it enables receiving feedback and updating of the technique for training operational personnel.

Gamification is considered as an approach to motivate and engage students in their learning process. An empirical study is carried out here on the use of gamification techniques in two engineering courses, in the field of Thermal Engineering, taught in two Spanish universities during several academic years. Both courses have similar syllabuses, and require the understanding and application of relatively complex concepts, related to Thermodynamics and Heat Transfer. The aim of this work was to increase students´ motivation and to help them in the process of assimilating and establishing key concepts related to these courses. Students´ satisfaction with the activity was assessed by means of surveys designed and proposed according to the Student Evaluation of Educational Quality (SEEQ) model, using a statistical package. The students were quite satisfied with the participation in the activity, the teamwork, the organization, and the grades. However, they considered that the learning of concepts was stronger in traditional classes. No significant differences were found between degrees or group size. Incorporating gamification techniques has proved to have a motivating effect on students, getting them involved in learning and in the development of the course.

Alongside innovation in teaching practice, student assessment in chemical engineering has seen significant changes in the recent past. This article undertakes a systematic review of the recent advances that have been reported in assessment practice in chemical engineering education. The main trends that emerge are: a shift towards authentic assessment methods, an increase in emphasis on peer-assessment and other approaches for group-based assignments, and a greater use of digital tools for the delivery of authentic assessments and improvement of marking and feedback practice. The analysis also examines the diversity of assessment methods used across the different chemical engineering subjects and how these map against assessment frameworks reported in the wider pedagogical literature. The emerging strand of research on synoptic and interdisciplinary assessment is used to develop an assessment framework for producing chemical engineering graduates who are also socially responsible and competent global citizens.

Rigorous calculation methods to simulate multicomponent distillation processes involve large number of variables and equations that are difficult to solve by hand and require the use of specific software. With this purpose, commercial process simulators have been included for years as learning tools in the syllabus of Chemical Engineering degrees. Nevertheless, there is thus a possibility of using these packages as a black box and strategies to mitigate that risk have been developed, as the use of spreadsheets where students can follow and check the calculation algorithms and the details of such calculations. One alternative to solve multicomponent distillation problems is the use of relaxation methods, that find the steady-state solution of a continuous distillation column by solving unsteady-state equations from a specified initial condition, thus providing an analogy with the column startup. In this work, a novel spreadsheet to apply a relaxation method is proposed. Calculation begins with the simulation of a distillation column at total reflux, which is a common way to start up these processes. In order to facilitate the development of unsteady-state equations and operation, a batch distillation column is also simulated. Finally, the evolution of a continuous distillation column from a specified starting condition to steady-state is simulated.

The business sustainability of technological companies such as those operating in the extractive sector requires multi-faceted talented individuals able to invent and deploy cutting-edge technologies, minimize environmental footprint, secure financial stability, achieve and maintain the social license to operate, among other challenges. These requirements echo those needed for addressing grand challenges such as the Sustainable Development Goals presented by the United Nations. However, traditional educational programmes are structured within the silos of well-defined academic disciplines. This lag between industrial need of individuals proficient in a variety of disciplines, and the professional figures prepared by most academic establishments could be due to a combination of several factors, including (a) the difficulty of offering programmes that require expertise from across several academic departments, and in some cases universities; (b) the perceived lack of interest among students for learning about interdisciplinary challenges; and (c) the possibility that graduates from interdisciplinary programs might not be easily hired by corporations operating in related disciplines. Reflecting on the efforts required to establish the postgraduate masters’ program in ‘Global Management of Natural Resources’ (GMNR), we suggest a possible pathway to overcome the first of these hurdles. After five years of offering the GMNR program, we assess the latter two perceived hurdles using the responses to a questionnaire distributed among the graduates. In particular, we quantify whether the graduates have experienced benefits or hurdles in their professional careers directly related to their graduation from an interdisciplinary program. The results could help the community develop and when necessary improve interdisciplinary programs, which could allow industries to overcome their future challenges, and perhaps contribute to achieve the UN Sustainable Development Goals.

Green engineering education is of great significance. The development of the chemical industry has a new direction under the background of engineering back to green engineering and chemistry. The undergraduate graduation chemical design is an important course for the comprehensive application of professional knowledge and bridging to the actual production, and also important support for the cultivation of chemical talent. This paper presents a case in which the improvement of ethyl acrylate process design can be selected as a topic of undergraduate graduation chemical design, which has both an industrial production process foundation that student can learn and engineering design innovation under the guidance of the green engineering concept. After the design study, the results show that the process design of ethyl acrylate supported by new clean catalysis and membrane separation technologies has been improved in reducing process complexity and improving environmental friendliness. Furthermore, the teaching result indicates that the process design reinforces students' green engineering thinking and provides a green engineering teaching format for chemical design.

Educators in chemical engineering have a long and rich history of employing digital tools to solve fundamental engineering problems. Today, with the megatrend of digitalisation, there is a growing set of tools that can be used for chemical engineering education. However, identifying which tool is ideally suited to support teaching a given chemical engineering concept can be challenging. To answer this question a survey was distributed to Heads of Departments at IChemE institutions and members of the IChemE committees focused on digitalisation. The survey respondents rated Microsoft Excel (VBA), commercial simulators, and scripting tools as ideal for teaching core subjects such as mass and energy balances, mass transfer and reaction engineering while respondents found 3D Models, and Virtual/Augmented Reality models as being most suited for teaching subjects such as process design, safety and sustainability. Mathematical/programming simplicity, ease of maintenance, and low initial investment costs were identified as key non-technical aspects that will hinder the adoption of a given digital tool. Weighing the benefits of education and non-technical hurdles, the respondents preferred the use of simpler digitalisation platforms such as Excel and scripting languages over the more advanced platforms such as Virtual/Augmented Reality where possible. It was identified that the widespread adoption of more advanced digitalisation tools will require removal of the above mentioned non-technical barriers as well as other barriers such as tool shareability.

The extent to which learners have scope and opportunity to direct and influence their own approach to learning activities, what may be termed ‘learner agency’, has been shown to be important for students across many disciplines, in developing key advanced skills and qualities such as self-efficacy, critical thinking, resilience and innovative problem-solving. Employers unsurprisingly value graduates able to exhibit and cope with agency in their approach to work through such elements as self-learning ability, capacity to formulate and solve open-ended problems, coping with unfamiliar situations, and effective teamwork. Here, through a student-led and student-designed research project using questionnaire and interview methodology, we explore via the perceptions of students themselves how a typical UK Chemical Engineering BEng/MEng curriculum provides opportunities for agency and how students feel they cope with agency. We examine the curriculum class-by-class and year-by-year, studying correlations and patterns in the types of learning activity which students perceive as enabling them to exert influence and control over learning. In follow-up one-to-one interviews we further examine the link between perceived degree of agency and critical thinking skills, as measured by standardized scales, to explore how perceived agency-delivering activities may correlate with actual developments in thinking styles and skills.
