EXTRACTION AND CHARACTERIZATION OF VEGETABLE OIL USING BREAD FRUIT SEED.

ABSTRACTA vegetable oil is a triglyceride extracted from a plant. Such oils have been part of human culture for millennia. The term "vegetable oil" can be narrowly defined as referring only to substances that are liquid at room temperature, or broadly defined without regard to a substance's state of matter at a given temperature. For this reason, vegetable oils that are solid at room temperature are sometimes called vegetable fats. Vegetable oils are composed of triglycerides, as contras...

Production and characterization of briquette from chat residue

Briquette is a block of compressed materials suitable for burning. Briquettes can be made from low cost materials such as old newspaper, any bio mass wastes and agricultural residues. They can be used as fuel instead of charcoal, firewood or mineral coal and costs less. Depending on which materials were used to make the briquettes, they may burn cleaner than charcoal. Finally, turning waste materials into a fuel source is attractive because it reduces waste as well as reducing the demand for ...

Production Of Biodiesel From Jatropha Crop

ABSTRACT:    The interest in using Jatropha  curcas  L.  (JCL)  as a feedstock for  the  production  of  bio-diesel  is  rapidly  growing.   The  properties  of  the  crop  and  its  oil  have  persuaded  investors and policy  makers to consider  JCL  as  a  substitute  for  fossil  fuels  to reduce  greenhouse&nbsp...

Biostimulation Of Crude Oil Contaminated Soil Using Local And Foreign Stimulants

ABSTRACT Bioremediation is an important technology for the restoration of oil polluted environments by indigenous or selected microorganisms. In general, the rate of biodegradation depends on the number and types of micro-organism, the nature and chemical structure of pollutants to be degraded and the environmental conditions. In this study, the efficacy of the biodegradation potentials of foreign (  PETROX HC 500, PETROX HC 600, PETROX HC 100, PETROX HC 1150 AND PETROX HC 339 ) and loca...

Cryogenic Science And Engineering

   ABSTRACTThis report is intended for a general insight into cryogenics. Different individuals may have faint ideas about what cryogenics are as much is not known here in Nigeria about what cryogenics are and this report work clearly gave a deeper knowledge of cryogenics     Chapter one gives a brief history of cryogenics and the various cryogenic temperatures that have been achieved since 1800 to 1965. Chapter two gives a general knowledge of the fundament...

Design and Performance Evaluation of a Waste water Treatment Plant.

The study aimed at the design, construction and performance evaluation of a model domestic wastewater treatment plant was carried out. The treatment unit was a Waste Stabilization Pond (WSP) comprised of one facultative pond, three maturation ponds, and a contact filtration unit, all in series. The effluent of the WSP, after filtration through clay media, had the BOD reduced to 15.4mg/l, from 356mg/L indicating a 95.67% removal level. A Faecal Coliform (FC) count of the influent sample gave 1...

Design Construction and Performance Evaluation of a Model Waste Stabilization Pond

The study aimed at the design, construction and performance evaluation of a model Waste Stabilization Pond (WSP). The WSP comprised of one facultative pond and three maturation ponds all in series. The influent of the WSP after filtration through the lined sandy loam media (obtained from the premises of Federal University of Technology, Owerri, Nigeria) had the BOD reduced to 22 mg/L from 356 mg/L indicating a 93.8% removal level. A faecal coli form count (fc) of the influent sample gave 1×1...

EVALUATION OF THE EFFECTS OF ANTHROPOENIC ACTIVITIES AND DOMESTIC WASTE ON SURFACE WATER QUALITY (A CASE STUDY OF EKULU RIVER, ENUGU).

ABSTRACTThe microbiological and organic pollutants characteristics of umuosoko stream in ikwuano local government area, Enugu state, Nigeria were carried out. Twenty water samples were collected from four different parts of the river.  The pour plate technique was employed for the isolation of micro-organisms. Colonial morphology, Gram staining and biochemical tests were used for identification and characterization. The statistical analyses used were analysis of variance and standard dev...

EVALUATION OF THE EFFECTS OF FLOODING ON THREE VARIETIES OF RICE (A CASE STUDY OF ABAKALIKI, EBONYI STATE)

ABSTRACTFlooding has been described as one of the most important environmental factors determining the distribution of salt marsh plants. We studied the impact of five water levels on the germination and establishment of the invasive cord-grass spartina deniflora. Plant house experiment was carried out to determine the effects of time and depth of flooding on the survival and growth of rice. Data showed that time and depth of flooding had significant effects on the survival and growth of rice...

COMAPARISM OF THE EFFICIENCY OF SAWDUST, COCONUT FIBRE, WOOD CHIPS IN PURIFICATION CRUDE OIL POLLUTED WATER

ABSTRACTA comparative study was conducted among organic waste materials namely coconut fiber, hair, sawdust and woodchips as crude oil absorbents. Twenty grams of each of these materials were wrapped in a pouch and submerged into two set-ups, Set-up A: Pure Crude Oil and Set-up B: Crude Oil with seawater, for an hour. Amount of oil absorbed was gathered and recorded. ANOVA was conducted to verify if the results significantly differed. The results show that hair had the highest amount of ...

Public Transportation: The Role Of Government And Private Enterprise

ABSTRACTTransportation is a requirement for every nation, regardless of its industrial capacity, population size or technological development. The Nigerian transport systems, right from inception, were poorly designed and are unable to scale up to meet greater demand, a design flaw which causes traffic congestion on roads, overstressed railways, faltering airfields, and mass-transport blind spots. Overall there appear to be market impediments which operate to limit the extent to which Nigeria...

CONSTRUCTION OF A STANDARD DRAWING DESK

ABSTRACTThis project is a fabrication of a standard drawing writing desk using the cheapest, effective and most readily available materials. Method of maintenance and services were also taken into consideration. The functional aspect of the equipment was also given adequate consideration in the project work. Also take into consideration the reliability, portability and general values, appearance of the equipment. A material used for the construction was of best quality, which have excellen...

THE COMPARATIVE ANALYSIS OF THE STRENGTH OF CONCRETE MADE FROM VARIOUS AGGREGATE

ABSTRACTThe work has gone a long way in determining strength of concrete made of various aggregates such as granites stone, black gravel, washed gravel and surface gravel.Some factors such as porosity of the  aggregate temperature coursing lose of water plate form for mixing of concrete mix affect the workability and eventually the strength of concrete.This project work consist of using hydraulic machine to carryout the compressive test of the strength of concrete made of the earlier men...

ANALYSIS AND DESIGN OF A RETAINING WALL

INTRODUCTIONRetaining walls are structures used  in providing stability for earth or materials where conditions dis allow the materials from summing its nature al slope or stabilityThere are many factors affecting or militating against the stability of retaining walls. These includes the level of water table behind the wall, size of the base of the wall and nature of the soil retainedUnder these effects of he nature of soil,. we have the angle of internal content between the particles, t...

COMPARATIVE ANALYSIS OF THE STRENGTH OF CONCRETE MADE FROM VARIOUS AGGREGATE

INTRODUCTIONThis work was obligated to present in one. The fundamental and practical information in the filed of the comparative analysis of the strength of concrete made from various aggregate which may be useful to people involve in civil and structural engineering and particularly, those that found pleasure in the design and related structure.Due to high cost of sand in the market the  comparative analysis of strength of concrete  made from various aggregate play an important rol...
