Abstract It is of no doubt that one day, fossil fuels, which the whole world highly depends on, will come to a halt in a few decades to come. To this reason, researches have been geared towards alternative sources of energy: biodiesel, a form of renewable energy (energy that can be regenerated once used up), is one that has been made known and being tested in some parts of the world. Due to the fact that biodiesel is hygroscopic (absorbs water readily from the atmosphere), as well as other fa...
Natural gas is one of the major sources of fuel and raw material to industries all over the world. However, it contains some acid gases such as CO2 and H2S which are corrosive and harmful to the environment. These acid gases must be brought to permissible limits to promote safety in the operation and increase the heating value of the natural gas. In this project, we design an acid gas removal plant based on the amine treatment process using ASPEN HYSYS software. In our propose...

ABSTRACT The study aimed to assess the quality of drinking water in Olowotedo community of Ogun state, Nigeria. Five samples were taken from different sources (wells, borehole, tap and sachet water) were analyzed, Selection of water samples was carried out using proportionate allocation, equal allocation, simple random sampling and systematic sampling methods depending on the stage. The water quality parameters examined and their results for all the five water samples were; colour having...
The energy generation and power consuming loads at Brass LNG facility located in Brass Island, Bayelsa State Nigeria were analyzed and compared with expected demand changes and means of minimizing cost and greenhouse gas emission were also proffered with wind and solar energy penetration into the overall power mix . The wind and solar hybrid power generation system reduced the fuel consumption, greenhouse gas emission and noise pollution by the generators and turbine by relieving some of the ...
Since the inception of the Private Finance Initiatives (PFI) in the United Kingdom, Government are increasingly adopting it as a means of proving infrastructure to the public neglecting the traditional procurement methods which relies completely on the public finance. Private Finance Initiative (PFI) is a method of contract procurement where the private organisation provides an infrastructure, finances, operates and maintains the infrastructure. This is done by transferring the risks involved...
ABSTRACT The AVR is automatic voltage regulator and it is a device which is used to regulate or stabilize electrical power supply for electrical or electronic appliances In this project, therefore, we are interested in the construction of this all important device. Furthermore, we shall discuss the techniques, processes, switching stages and then the working principle of the automatic voltage regulator Chapter one of this project dwells on the introduction of the pr...
ABSTRACT Automatic voltage inverter is an important area in power system engineering. It is the process of using a 12v DC from the battery to achieve a 220/230V AC through the help of oscillator, drivers, power transistors and transformer. The stages are battery to oscillators, oscillators to drivers, drivers to power transistors then from power transistors to transformer which is capable of giving out 220/230V (1000w) as an output. A 1.25KVA (1000w) voltage inverter was construct...
Voltage stability is a major concern when planning and operating electrical power systems. As demand for electric power increases, power systems are stressed more and more. Since the construction of new transmission lines is very expensive, and the right of way requirements are not easy to come by, a cost-effective policy is to use the existing lines to their maximum thermal and stability limits, and this requires optimum sharing of power flow in the system. Flexible AC Transmission Systems ...
ABSTRACT The design of 2 tones automated hydraulic jack was carried out using the basic principles of machine design and analysis. The hydraulic jack was designed with a 204watts wiper motor with the output lever having a torque of 30Nm. The effective diameters of ram and plunger pistons were found to be 12mm and 6mm respectively, when the load lifted was 2000N with mechanical advantage being 3.4. The working stress was 21MPa when the effort applied at the handle by the lever was 594.3N. ...
ABSTRACT As Nigeria aims at optimizing the implementation of the E-learning programme in tertiary institutions, this paper discusses the ways by which the implemented E-learning can be sustained. The discussion was carried out using data derived from students, teaching staff and telecommunication engineers in Nigeria using Owerri metropolis as a case study. Data analysis was carried out and analyzed using excel and Minitab. Conclusions and recommendations were drawn for effective implementa...
The ability to analyse the performance and forecast the production of gas wells is important in gas reservoir engineering. Information like the reservoir permeability, damage and improvement, reservoir pressure etc should not be faulty because when faulty, estimation of information that involved them will also be faulty which will in turn depicts wrong forecast of the gas well. To obtain a reasonable degree of accuracy, different analytical methods have been studied and applied to modern gas ...

Time has come for people to know the implications of engaging non-professional builders in building construction works. The stoppage of engaging non-professional builders would reduce or even stop the event such as shoddy works, use of inappropriate materials/personnel’s and abandonment of project, cost overrun, and inadequate supervision/incompetence and incessant collapse of buildings. This project therefore delved into the imperative of engaging professional builders in building cons...
