Renewable energy: desktop learning module for gasification processes

PI: Idris Bugaje (National Research Institute for Chemical Technology)
U.S. Partner: Bernard J. Van Wie (Washington State University)
Project Dates: August 2013 to September 2015

Gasification is a promising process that can be used in promoting the commercialization of drop-in fuels produced from renewable sources. Gasification is, however, a complex process that entails both simple and complex reactions that could be very difficult to comprehend. The advent of Desktop Learning Modules (DLM) in engineering education has been shown to increase conceptualization, as evidenced by numerous publications from the U.S. partner on the project, Dr. Van Wie. In this PEER Science project, Dr. Bugaje and Dr. Van Wie will extend previous DLM-related work that the latter has carried out with Ahmadu Bello University, originally targeting fluid mechanics and heat transfer, to biofuels education by developing a DLM system for a gasifier process. This will serve as an excellent means of introducing both students and researchers into the field of gasification and enhancing their understanding of the process. Currently, such a simple and yet important set-up is not available. Designing such a process to work in the developing nation of Nigeria will serve to educate and train the next generation of workforce personnel who will promote and implement renewable energy processes. Furthermore, because the process will be self-contained and self-powered, it will be designed to work in domains where electricity and water utilities are intermittent or even non-functional – this itself will allow use as well as personnel training in remote areas where renewable energy is most needed. It will also provide an inexpensive teaching and learning device that can be used worldwide, especially in programs with low budgets and less than desirable access to utilities.

It is expected that the desktop learning system will serve as a learning module for the general introduction of the concept of gasification and pyrolysis as well as a basis from which laboratory data obtained could be used to design an up-scaled pilot plant. At the planned research institute, the learning module will serve as an instructional guide for teaching the concept of gasification with application to industrial processes. This should be especially useful to engineering students temporarily attending the National Research Institute for Chemical Technology on industrial attachment. It will serve as a test platform and display system so that the desktop learning module can be extended to other educational and research institutions. It is expected to provide learners with an overview of the concept and stimulate the development of desktop learning modules for other challenging engineering processes.

Summary of Recent Activities
 
 
The fourth quarter of 2014 saw remarkable progress in the actualization of the desktop learning module for bio-fuel production. Having selected a suitable process and carried out material and energy balances for the various units selected for each unit, the team finalized the overall design. In order to reduce variability, increase efficiency, and ensure the safe operation of the proposed DLM, various controls were installed including temperature, pressure, and level alarms, and, in line with established safety requirements, a preliminary hazard analysis was performed. Additionally, start-up and shutdown procedures for the DLM were outlined to ensure its safe operation. With the completion of the paper design of the DLM gasifier and the syngas cleanup unit in this past quarter, efforts in the new year will be geared towards practical actualization of the design.
