ABSTRACT This project (construction of a simple size reduction machine) it was constructed locally with the use of local materials and tools in I. M. T. mechanical engineering workshop. The various parts of the equipment were constructed separately using mild steel before finally coupled. During the construction, the conveyors and its housing where first constructed. It consists of a shaft with helical rod wound round it. The paper was measured out and welded from a mild steel sheet of le...
ABSTRACTThe sets of seizes with shaker which was fabricated and assembled in the Chemical Engineering pilot plant was aimed at providing the students with a machine that will aid them in practical involving the separation of solid particles, besides, this, it was also fabricated sizes or diameter of the solid particles of a substances by allowed it pass through the pores or a partures of the size plates. The process of operation involved the following: Marketing out of the sieve plate u...
ABSTRACT As a result of modern development in Science and Technology, most of the large scale industrial used machine were now modernized to simple small and efficient machines. Some of these machines were either operated manually or the aid of electricity. For this reason, big metal sharpening machine was here reduced to simple term, which can be operated manually such as file and grinding machine for production firms and homes. This machine performs the same functions as the...
ABSTRACTA paint mixer is defined as a pattern constructed for the production (mixing) of paint manually. The method of fabrication of the paint mixer involved a preliminary computation of the dimensions of the standard mixer in relation to the dimension of the reacting vessel in which they will be used in marking out, cutting out to sizes, rolling, folding, welding, body-filling and painting. The first step taken in the fabrication of this project work was the selection of material suitab...
ABSTRACTEffect of temperature on viscosity and density changes on neem biodiesel and neem biodiesel-blend has been investigated. Neem oil was sourced from neem (Azadirachta indica) seed, which was extracted using soxhlet apparatus and was converted to biodiesel using transterification method. The fuel properties of the resultant biodiesel such as viscosity, density, cetane number, cloud and pour points, flash point, were measured. At varying temperature range of 25-100OC, changes in viscosi...
ABSTRACT The aim of this research work is special formulation of liquid detergent for car wash. In manufacturing liquid detergents, selection of raw materials is been considered as the first step. These raw materials were selected on the basis of several factor such as human and environmental safety, cost compatibility with other ingredients and also the specific properties desired in the final products. Liquid detergent (car wash) is regarded as chemical formulation which essentially consis...
ABSTRACT A common misconception about stainless steel is that it is not affected by corrosion. Although one of the main reasons why stainless steels are used is corrosion resistance, they do in fact suffer from certain types of corrosion in some environments and one of such types is crevice corrosion. Crevice corrosion is normally a consequence of a galvanic cell generated in specific areas with restricted flux. Crevice corrosion is a form of localized corrosion in which a metal in contact ...
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 local ma...
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 gas emissions. In this report, we gave an overview of the currently available information on the different process ste...
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 ...
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 contrasted w...
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...
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...
ABSTRACT The 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 w...
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°
