S.; Oladimeji E.; Abatan O.; Ayeni A. O.; Agboola O.; Ayoola A. A.; Ojewunmi M. O.; Efeovbokhan V. E.Biomass gasification and the production of syngas are important in the production of biohydrogen, a green fuel and an energy carrier for the fuel cell. The tool for the prediction of biohydrogen production from any biomass should be readily available to determine the viability of such biomass for gasification. The software implementing a robust gasification model is complex, proprietary, and expensive. In order to solve this problem, we developed Gasific, a software module for simple, free, and accurate biomass gasification product gas prediction. Gasific, implemented biomass gasification, stoichiometric equilibrium models, in Python and runs on a variety of platforms. We discussed the application of Gasific on biomass wastes, namely, Imperata cylindrica; the simulation shows good performance in predicting the gas composition product of gasification. The developed software and the code can be modified and applied to other scientific models and transform the models into software applications.Item Modelling and simulation of the volume flow of NH3, K2CO3 and for the Carbon dioxide absorption from coal(2021) Nkhwashu M.

E.; Oyedemi M.; Emetere M. E.; Agboola O.; Adeoye J. B.; Odunlami Olayemi A.The incidence of water pollution in developing countries is high due to the lack of regulatory policies and laws that protect water bodies from anthropogenic activities and industrial wastewater. Industrial wastewater contains significant amounts of heavy metals that are detrimental to human health, aquatic organisms, and the ecosystem. The focus of this review was to evaluate the sources and treatment methods of wastewater, with an emphasis on technologies, advantages, disadvantages, and innovation. It was observed that conventional methods of wastewater treatment (such as flotation, coagulation/flocculation, and adsorption) had shown promising results but posed certain limitations, such as the generation of high volumes of sludge, relatively low removal rates, inefficiency in treating low metal concentrations, and sensitivity to varying pH. Recent technologies like nanotechnology, photocatalysis, and electrochemical coagulation have significant advantages over conventional methods for removing heavy metals, including higher removal rates, improved energy efficiency, and greater selectivity for specific contaminants. However, the high costs associated with these advanced methods remain a major drawback. Therefore, we recommend that future developments in wastewater treatment technology focus on reducing both costs and waste generation.Item Role of Biomaterials in Automation(International Conference on Energy and Sustainable Environment (IOP Publishing), 2021) Fayomi O.
