The research study presents the development of a model for Energy cost in manufacturing industries under irregular power supply. The work considers power consumption in the operation of production machines, hence cost incurred in running of these machines Parameters such as machine types for production, numbers of machine types for production and power ratings of machines for production were also considered in the development of the model The study employs linear programming approach in formu...
Kenaf reinforced polyethylene composites for ballistic protection was produced in this work. The samples of alkaline treated and silane-coupled non-woven matted kenaf fibers were cut to the required dimensions and oriented vertically and horizontally in combinations with a virgin high density polyethylene (VHDPE). The composite panels were produced using Box-Behnken 3-variables settings. The following factors settings were used (molding temperature: 160 0C to 200 0C; molding time: 60 minute...
Abstract A smoke detector is a device that senses smoke typically as an indicator of fire or non- smoking zone. In order to ensure human safety and safeguard property against fire in both domestic and commercial settings, different solutions for smoke detection have been developed, a comprehensive literature was carried out on smoke detector, this project describes the construction and design of a micro controller smoke detector, it discusses the components used, design methodology and test...
ABSTRACT The potential advantage and application of the photocatalytic process using titanium dioxide as the photocatalyst to treat industrial waste water in UV irradiation has been reported. The aim of this work is to investigate the effectiveness of photocatalytic degradation using TiO2 in treating pharmaceutical waste water. Wastewater was collected from the homogenous tank of effluent treatment plant (ETP) of a Pharmaceutical company. The raw sample was tested and the COD, BOD and pH we...

ABSTRACT Tree residues are generated in large quantity in our environment. Nowadays, adding value to these residues could make them become item of economic importance. The aim of this study is to adapt a traditional method of charcoal production (Earth Mound) in order to add value to the tree residues generated in University of Ibadan with a view to enhance the benefit derived from them. The billets of Acacia nilotica were converted from both wet and dry wood samples. The billets were t...
Abstract The cost of managing ornamental and naturally growing trees in the University of Ibadan, Nigeria, is becoming challenging. Adding value to the residues from these trees with a view to enhance its economic value will minimize the management cost. This study adapted Earth Mound method of charcoal production to add value to tree residues generated in the University of Ibadan to enhance its economic value. Mixed residues of Acacia nilotica (Acacia), Albizia zygia (Ayunre) and Melicia ex...
ABSTRACT Wood Plastic Composite panels were produced using a locally fabricated extruding machine at a temperature of about 170°C-200°C. the Sawdust of Anogeissus leiocarpus(Ayin) and Recycled Polyethylene Teraphthalate (PET) Chips were mixed in the ratio 1:1 to 1:5 and densities of 770.58 kg/mm3, 888.65 kg/mm3, 1,114.71 kg/mm3, 1,117.58 and 1, 141.84 kg/mm3 respectively. The quantity of recycled polyethylene teraphthalate (PET) Chips and sawdust used in the panels production were later...
An energy audit on the Brass Liquified Natural Gas plant at Brass Island former Agip facility was carried. The average offshore windspeed and wave return periods for 12months were measured for their wind and wave energy potentials. Also, the solar insolation for the location was collected for a 12month period. A pilot design based on techno-economic analysis was made for a wind-solar- gas turbine hybrid power system and results showed it's cheaper, environmentally friend, and more efficie...
ABSTRACT This project work deals on the feasibility of transferring the Toe – To – Heel Air Injection (THAI) technology which is a new in-situ combustion method of heavy oil recovery from Alberta, Canada, where the technology has recorded success with high rate of recovery to South-West, Nigeria (Ondo state) for efficient heavy oil recovery. In this work, the textural, reservoir, physical and chemical properties of oil sand in Nigeria were compared with that in Canada where the t...
ABSTRACT The advent of sachet and bottled water has increasingly filled the gap in household water security. This research work was carried out to assess the quality of bottled and sachet water sold in Bauchi metropolis. Thirty (30) water brands consisting of twenty (20) sachet water brands and ten (10) bottled water brands were assessed for their physical, chemical and microbiological parameters using standard analytical procedures. Physical examination was carried out...
Carbon steel corrosion is a commonly encountered issue in pipelines transporting hydrocarbons containing corrosive agents such as CO2, H2S and water. As a result, several corrosion prediction models have been put forward over the years although no standard model exists for corrosion prediction in the industry. Two of such models are the Norsok model for predicting sweet generalized corrosion and the Papavinasam model for predicting localised corrosion which are both insufficient to accurately...
The household lighting cost accounts for 10% of the electric bill, changing the light bulbs effectively can reduce the long term energy costs significantly. In Nigeria, where less than one percent of the population has access to 24 hours of interrupted power supply there is a need for a complementary, renewable source of light which provides enough illumination at a reasonable price, with assured safety using it and also using for a long duration of time before the need to replace it. Recentl...
