MODIFICATION OF SURFACE, PHYSICAL AND CHEMICAL PROPERTIES OF ACTIVATED CARBONS FOR WATER PURIFICATION

ABSTRACTThe purpose of this work was to study the effect of chemical surface properties of activated carbons for their use in water purification. To achieve this objective, activated carbon in both granular and powdered forms namely: as received and devolatilized carbons were prepared. Proximate analysis of the carbon materials was performed. Mass titration experiments were carried out to determine the point of zero charge of the activated carbon materials. Again, using an ultraviolet spectro...

THE PRODUCTION OF BENCH SHEARING MACHINES

INTRODUCTION  The production of bench shearing machines to reduce, alleviate and probably eliminate suffering, time, money, wastage of material and more especially the need for technological break through and self reliance has been a major concern of the federal government. Metal shearing and shaping has been a tiring problem in the society from time immemorial especially toward our loco-parcatesis. To help eradicate these problem this project write up has delved  into simplicitie...

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 ...

REFINING OF SOYA BEAN OIL

ABSTRACTThis project work studied the refining of crude soya bean oil extracted from soya bean seed using alkali /caustic refining method. The work was carried out using phosphoric acid for the degumming /pretreatment process and sodium hydroxide for the neutralization /refining of the oil. Certain tests were carried out on both the crude and refined oil such as saponification value, acidic value, iodine value, specific gravity and viscosity, the results obtained after the tests include 42.07...

REFINING OF PALM KERNEL OIL

ABSTRACTThis work studied the refining of crude palm kernel oil derived from the kernels within the nut of a palm fruit.This research project was aimed at reducing the non-glycerides present in oil in their crude form using an alkali method of refining.The crude palm kernel oil was first washed with distilled water by heating the mixture in an electric heater for about 2 hours to reduce the impurities present in the oil in their crude form, degummed with phosphoric acid and neutralized with N...

THE KINETIC STUDY ON HYDROLYSIS OF CELLULOSE (SAW-DUST)

ABSTRACTThis research project studied on the kinetics of hydrolysis of cellulose to glucose. The steps employed to achieve this project involved extraction of cellulose from sawdust and subsequently, hydrolysis of starch to simple sugar. This was followed by glucose analysis. Different experiments were conducted during acid hydrolysis to study the various acids on the hydrolysis of cellulose to glucose. The saw-dust was extracted from the wood by grinding using saw. The process used in the hy...

THE EFFECT OF TEMPERATURE ON HYDROLYSIS OF CELLULOSE (SAW-DUST)

ABSTRACTThe effect of concentration of hydrochloric acid on hydrolysis of cellulose (sawdust) to glucose was studied on this research project and the steps obtained to achieve this project involved treatment of saw-dust (cellulose) with different concentrations of the acid at constant temperature of 80°

THE PRODUCTION OF YAM FLOUR

ABSTRACTThe project dealt on the production of yam flour from yam chips. The yams were peeled and washed, 100grams samples coded sample A to G were subjected to two different drying conditions. Some were dried using the sun drying method while the others were dried through oven drying method kept at constant temperature of 500C, sodium bi-carbonate was added to some of the samples, all these were done to obtain a flour with the best colour and texture quality. From the results obtained, it wa...

A COMPARATIVE ENTHALPY APPROACH FOR CO- AND COUNTER CURRENT FLOW IN CONCENTRIC TUBE HEAT EXCHANGER

ABSTRACTAccording to the modern or dynamical Theory of heat: Heat a form of energy. The molecules of a substance are in parallel motion. The mean Kinetic energy per molecules of the substance is proportional to its absolute temperature. In description of heat, a molecule may consist of one or two or many atom depending upon the nature of the gas. The force of attraction between the molecules of a perfect gas is negligible. The atom in a molecules vibrate with respect to one another, consequen...

ANALYSIS OF CRUDE PALM OIL

ABSTRACTThis project was carried out to ascertain whether the local palm oil met the required standard.  The analytical test carried out include the free fatty acid test the acid value, iodine value moisture, content, saponfication value, peroxide value, specific gravity, colour and viscosity.The specific gravity of the oil sample was determined by comparing its weight when filled with the sample and that of water, while its moisture content was analyzed by oven drying the sample for a p...

ASSESSMENT OF THE PHYTOCHEMICAL CONSTITUENTS AND PROXIMATE COMPOSITION OF AFRICAN PEER.

ABSTRACTPlants are important in our everyday existence. They provide our foods, produce the oxygen we breathe, and serve as raw materials for many industrial products such as clothes, foot wears and so many others. Plants also provide raw materials for our buildings and in the manufacture of biofuels, dyes, perfumes, pesticides, adsorbents and drugs. The plant kingdom has proven to be the most useful in the treatment of diseases and they provide an important source of all the world’s pharma...

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...

Construction And Fabrication of Iron Truck of Capacity 200kg

ABSTRACTConveying goods from one place to another via trucks has been a long-held practice because of its usefulness. There are different types of trucks that are available in this regard such as ; two axle, three axle, four axle trucks etc and each with its unique functionality.Businesses relying on the movement of bulky raw materials and finished goods regardless of the distance no doubt require a truck to ease this task.In line with this challenge, it is desired to design and construc...

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 ...

Control of Nitrogen oxide emission

ABSTRACTIt is proposed to design a process plant that will control nitrogen oxide emission from a plant that is producing 90wt% nitric acid of 30,000 tonnes of nitric acid. This capacity is based on 8000hours of operation per year i.e. 330 days. It is proposed that this plant will be located in any location where there is substantial release of nitrogen oxides.The process plant will control about 90% of the nitrogen oxides being emitted from the nitric acid plant.The controller which is calle...
