CHARACTERISTICS OF LOCAL PRODUCED OIL FROM GROUNDNUT OIL

ABSTRACTThis project “Characteristics Of Local Produced Oil From Groundnut Oil” was carried out using ten cups of groundnut seeds that was purchased from a local market in Enugu metropolis.  The oil these seeds were in Enugu using solvent extraction method.  Two different solvents were used in the extraction namely: Ethane and order to compare their yield, physical and chemical properties.The extraction was carried out using 32og of size-reduced groundnut with 100ml of 17-hexane...

UTLILIZATION STUDIES OF ENUGU COAL

ABSTRACT This study has its theme as a utilization studies of Enugu coals with the view of studying its properties, classification, preparation storage etc comparing coals obtained from different locations. The Enugu coal is a sub-bitummous and non coking coal.  It is very rich in waxes and resins, thus it may be suitable for the production of liquid fuels and a range of chemical raw materials. After all necessary studies which includes proximate analysis, ultimate analysis, caeboniza...

Main Features of Pump and Pumping Systems

INTRODUCTIONThis section briefly describes the main features of pumps and pumping systems. What are pumps and pumping systems?Pumping systems account for nearly 20% of the world’s electrical energy demand and range from 25-50% of the energy usage in certain industrial plant operations (US DOE, 2004).Pumps have two main purposes:1. Transfer of liquid from one place to another place (e.g. water from an underground aquifer into a water storage tank)2. Circulate liquid around a system ...

DESIGN AND CONSTRUCTION OF A REFRIGERATING UNIT

ABSTRACT The design and construction of s refrigerating unit is handled from the knowledge of the working principles of laws of thermodynamics. The size of the containing vessel i.e the case as established to be of 45cm by 32 cm in dimension. The Angle iron mild steel to used in the fabrication and welding. The box case of two layers are fabricated. Plastic (cooler) box is then  placed inside the upper part with the other parts of the refrigerator were brought in. they were all fixed ...

DESIGN OF MOLTEN SALT COOLER IN PROCESS PLANT FOR PRODUCTION OF 2-7 X 104 TONNES/YR OF PHTHALIC ANHYDRIDE BY DIRET

ABSTRACTThe general approach to any design of a process plant involve an advanced network of Chemical Engineering processes.  This equipment design project was carried out to design a molten salt cooler (heat exchanger) for production of 2.7 x 104 tonnes/year capacity of phthalic anhydride by direct synthesis of gaseous naphthalene.The information concerning the design of this equipment was gotten from literature review which was then used to obtain the physical properties datas.  T...

CONSTRUCTION OF TABLE TOP LIQUIDLIQUID EXTRACTION UNIT

ABSTRACTA table top liquid-liquid extraction unit was constructed.  The project also involved the repair and servicing of peristaltic suction pump, by painting it, replacing the connecting cord to the power supply, refilling of the work out suction plates, teeth and general servicing of the equipment.  The glass absorption columns were provided as well as two yards length of transparent, soft, translucent synthetic chemical rubber (hose).  The two ends of the pipe were connecte...

DESIGN AND IMPLEMENTATION OF A WINDOW BASED FRONT-DESK INFORMATION SYSTEM (A CASE STUDY OF MAY FRESH SAVINGS AND LOAN LIMITED ONITSHA

ABSTRACT In account form analysis, a lot of discrepancies causes by manual aspect of the form such as: lost of form, inability to correct intakes, poor storage facilities have been a problem in the May fresh savings and loan limited account form. But in recent times, the computer has come to the aid of our banks, May fresh in particular.  The introduction of computer into the banking operation has to a great extent affected the mode of operation of banks in diverse ways. Computer has to...

WATER POLLUTION

ABSTRACT This seminar studied and analyzed Water Pollution, the causes, the effects, the sources, types and control of Water Pollution in the societies water pollution occurred when pollutants were discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds, Water Pollution affected plant, and organisms living in this bodies of water. Water pollution was known to be caused by the following factors, sewage and wastewater, marine dumping ind...

Design and Construction of an Automatic Power Changeover Switch

AbstractPower failure or outage in general does not promote development to public and private sector. The investors do not feel secure to come into a country with constant or frequent power failure. These limit the development of industries. In addition there are processes that cannot be interrupted because of their importance, for instance surgery operation in hospitals, transfer of money between banks and lots more. This paper presents the design and construction of an automatic power chang...

Design and Performance Evaluation of an Ice Block Making Machine

ABSTRACTThe ambient temperature of tropical countries like Nigeria is as high as 40oC during the dry season. This ultimately gives rise to increase in demand for ice which is used to reduce the temperature of water, soft-drinks as well as other uses. This increase in demand for ice block makes the design and construction of a machine which can be used for the production of ice within a short period of time in order to save energy and time imperative and a worthwhile venture. This paper presen...

THE STUDY OF PROPERTIES OF BRIQUETTE PRODUCED FROM GROUNDNUT SHELL COAL BLEND

ABSTRACTBiomass, particularly agricultural residues seem to be one of the most promising energy resources for developing countries (Patomsok, 2008). Rural households and minority of urban dwellers depend solely on fuel woods (charcoal, firewood and sawdust) as their primary sources of energy for the past decades (Onuegbu, 2010). Of all the available energy resources in Nigeria, coal and coal derivatives such as smokeless coal briquettes, bio-coal briquettes, and biomass briquettes have been s...

Design and Fabrication of an Ice Block Making Machine

ABSTRACTThe aim of this paper is to get a best performance by an ice block/cube making machine of refrigeration with suitable time. In present day hotels, resort and bar require more ice in very less time. So, to solve this problem and control the required time to ice formation, we construct an ice cube making machine. In present days, in market this machine is available with very high cost. So we try to make it at optimum price.Ice making machine consists of four key components; the evaporat...

A COMPARATIVE STUDY OF CHEMICAL AND MICROWAVE SYNTHESIZED ACTIVATED CARBORN FROM CORN COB

ABSTRACTActivated carbon, also widely known as activated charcoal or activated coal is a form of carbon which has been processed to make it extremely porous and thus to have a very large surface area available for adsorption or chemical reactions (Mattson et al., 1971). The word active is sometimes used in place of activated. It is characterized by high degree of micro porosity. A gram of activated carbon can have a surface area in excess of 500 m2. Sufficient activation for useful applicatio...
