O.; Alagbe E. E.; Sadiku E. R.; Popoola P.Laser cladding is a growing technological method that utilizes a navigating high power laser for melting a small region of the substrate; it has a function of trapping and melting entering powder particles. Hence, the process leads to the development of a new stratum. Aluminum alloy Matrix composites afford properties suchlike high wear resistance, high tensile strength, lightweight; this composites is finding wide applications in automotive industry. This review presents a brief discussion on laser cladding for aluminum base alloys for automotive industry with emphasis on aluminum alloys matrix composite for automotive industry.Item Short review on solvent resistance nanofiltration membranes for the treatment of waste water(2022-08) Agboola O.; Fayomi O. S. I.; Sadiku R.; Popoola A. P. I; Adegbola A. T.; Moropeng I.; Oyebanji J. A.; Oluwasegun K. M.With the potential wastewater generated in modern chemical industries, separation of organic at more extreme conditions is inevitable. On the account of finding a sustainable and effective separation, the preparation of solvent-resistant Nanofiltration (SRNF) membranes appeared to be a promising solution. In this review, a short overview on SRNF and its benefits was given. We highlighted the efforts made in using SRNF for some industrial applications like bio-refinery and petrochemical. The performance evaluation of SRNF for different applications was also discussed, briefly. Factors responsible for the Stability of SRNF membrane and classification of SRNF Membranes were also discussed.Item Short overview on the mitigation of corrosion in coal gasification plant(RESEARCH ARTICLE, 2022-08) Agboola O.; Fayomi O. S. I.; Adegbola A. T.; Moropeng I.; Sani S. E.Tn a coal gasification plant the performance of components significantly degrade over time under extremely sulfiding environments of the extreme temperature coal gas. The use of newly discovered organic corrosion inhibitor such as DNA from plants and animals could mitigate corrosion in coal gasification plant. However, reports have revealed the deposition of an appropriate coating on a low cost alloy could enhance components resistance to the attack of sulfidation; hence, minimizing capital and working costs. Here, we review the coal gasification process and methods of mitigation corrosion in coal gasification plantItem Review on the impact of heavy metals from industrial wastewater effluent and removal technologies(REVIEW ARTICLEVolume 10, Issue 23, 2024-12) Oladimeji T. 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 Review on coal-fired power plants from post-combustion CO2 process and challenges(TECHNOLOGIES AND MATERIALS FOR RENEWABLE ENERGY, ENVIRONMENT AND SUSTAINABILITY: TMREES21Gr, 2022-05) Agboola O.; Moropeng M. L.; Fayomi O. S. I.; Oyebanji J. A.; Oluwasegun K. MThe capturing of CO2 from power plant flue gases offers unique chance to alleviate the emissions of coal-fired power plants to the environment. The fraction of CO2 captured and the increased production of CO2 that results from loss in the whole efficiency of power plants are determinant factors for the net emissions reduction to the atmosphere via carbon dioxide capture storage. Post-combustion capture is of great interest as it is easy to implement as to existing power plants. The use of post combustion capture in power plant was reviewed. The challenges of post combustion process were reviewed with possible solutions.Item Modelling and simulation of the volume flow of NH3, K2CO3 and for the Carbon dioxide absorption from coal(2021) Nkhwashu M. I.; Moropeng M. L.; Agboola O.; Mavhungu A.,; Moropeng R. C.; Fayomi O. S. I.Item CONTROL OF FOSSIL FUEL GAS OPERATING CONDITIONS ON THE PERFORMANCE OF CARBON DIOXIDE CAPTURE PROCESS(2021) Letsholo I.; Moropeng M. L.; Mavhungu A.; Agboola O.; Fayomi O. S. I.; Moropeng R. C.Item Gasific: A Python Tool for Biomass Gasification Process(Advanced Manufacturing in Biological, Petroleum, and Nanotechnology Processing, 2022-04-04) Oladokun O.; Nyakuma B.; Luing W. 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 Data on the effect of Ibruprofen drug derivative on 430T1 stainless steel in acid solutions(International Conference on Engineering for Sustainable World (IOP Publishing), 2021) Sanni O.; Fayomi O. S. I.; Popoola A. P. I.; Agboola O.Item Empirical assessment of ammonia and urea concentrations in wastewater from a pharmaceutical plant: A case study(International Conference on Energy and Sustainable Environment (IOP Conf. Series), 2021) Sanni S E.; Odigure J. O.; Agboola O.; Emetere M. E.; Okoro E. E.; Audu C.In several ways, urea is one of the most prominent sources of fixed nitrogen due to its relative abundance in waste water treatment plants. In this study, the wastewater effluent from X-Chemical Industries was considered for hazard analysis in order to ascertain the water quality and impact at the outfall effluent of company X relative to environmental standards. The study period is for December, 2013 – February 2014. Based on the results, it was observed that at the company’s sluice gate, the desorber (primary treatment unit) did not perform optimally. Also, the variation of the parameters measured i.e. urea concentration, pH and ammonia concentrations exceeded the standards established by the World Bank, International Finance Corporation (IFC) and the National Environmental Standards and Regulations Enforcement Agency (NESREA), i.e. against the specified standard of 100 ppm, higher concentrations include December 3, 9, 11, 12, 19, 20, 21, 24, 25, 27, 28 and 29 with corresponding urea concentrations of 1457, 1970.4, 122.7, 163.2, 150.3, 171.4, 148.76, 270.78, 178, 123, 101.33 and 250.43 ppm respectively, whereas that of ammonia is higher than 5 ppm on December 3, 21, 24, 25, 26, 27, 28 and 29 with corresponding concentrations of 8.4, 9.69, 8.13, 9.45, 12.5, 6.98, 22.95 and 9.95 respectively, whereas, it was lowest on other days. It was also observed that the treated waste water advancing the creek (jetty) close to the plant, will have environmental consequences on marine lives such as marine micro-flora as well as fishes.
