DESIGN AND CONSTRUCTION OF 1000VA POWER INVERTER SYSTEM

ABSTRACT As the name of the project implies “Power Inverter”, is an electronics system that converts DC Energy (voltage) to an AC energy.  The major aim of this project is to design and construct a 1000VA Power inverter that is capable of powering loads of equivalent ratings, in the absence of power supply from NEPA or Generator. The system (power inverter) consists of the AC mains sensor section, Relay/change over section, Battery charger section, oscillator section, Driver sectio...

THE ROLE OF CHEMICAL ENGINEERS IN THE SOCIETY

ABSTACTMost of the critical condition societal problem such as conversion, storage and transportation of energy resources, food processing, preservation and supply, natural resources, development and recovery, their processing to final product, environmental quality control etc.hinge or the creative application of che- ical engineering. This led to the question “The role of chemical engineers in the society The net result is the persistent recruitment of other professionals by industri...

DESIGN AND CONSTRUCTION OF AUTOMATIC EMERGENCY LIGHT

ABSTRACTAs the name of the project implies “Automatic Emergency Light” is an electronic system that can provide light during emergency situations i.e when mains (NEPA) supply fails.  This system can provide enough light with full brightness in a given room or office.   The system makes use of white light emitting diodes for the lightings.  It is automatic in operation, in the sense that it can switch itself off when the battery charges full. Automatic Emergency light compr...

FORMULATION AND PRODUCTION OF LEVERA SOAP

ABSTRACTThe production of the soap was carried out using all the necessary equipments like the reactor, mould, stirrer, hygrometer guage etc. and all the required reagents for soap production in correct proportion.In the production, palm kernel oil (P.K.O) was used instead of tallow or grease.  This was because soap produced from grease or tallow tends to dissolve slowly at room temperature, whereas, soap of palm kernel oil product gives a quicker lather which is relatively suitable.Diff...

DESIGN AND CONSTRUCTION OF PUBLIC ADDRESS SYSTEM

INTRODUCTIONA public address system is an electronics sound amplification and distribution system with a microphone, amplifier and loud speaker used to allow a person to address a large public. The public address system consists of three main parts namely, the microphone (input transducer), amplifier and the loudspeaker (output transducer).The microphone picks up the sound and convert it to electronic signal in milivolts and this is fed to the amplifier for amplification. In this project, a d...

Utilization of Waste Plastic and Rubber for Commercial Purpose

ABSTRACTPlastic and Rubber materials have become the corner stone of our lives, so it leads to generation of huge quantity of waste. These waste materials are either mixed with municipal solid waste or dumped in an open area leading to increase in the area covered under waste land. Plastic and rubber waste, if not recycled is either land filled or incinerated, where both of them prove to be a disaster to environment. Incineration leads to air pollution whereas dumping the waste in open areas ...

Evaluating the Different Methods of Corrosion Prevention, Control and Monitoring

ABSTRACTThis research work was carried out to evaluate the different methods of corrosion prevention, control and monitoring. In the course of the research many scholarly articles on the subject matter were reviewed from which the researcher got lot information concerning the topic at hand. Thus making the research work a reliable source of information as far as facts about corrosion is concerned. To ensure this work satisfies the quality expected of it, an experiment was carried out by ...

THE EFFECT OF LIQUID FLOERATE AND GAS FLOWRATE ON A PACKED ABSORPTION TOWER AND REPAIR OF EQUIPMENT

ABSTRACTThe purpose of the project is to study the effect of liquid flow rate and gas flow rate on the pressure drop in a packed absorption tower and also to repair and restore the packed absorption tower to good working condition.Trouble shooting revealed that the exit drain value was broken due to carelessness on the part of former user of the equipment.  We had to carry out glassblowing operations using borosilicate glass to construct another value.  Once this was done pressure b...

DESIGN AND FABRICATION OF A 12M3 MOBILE DEEP FREEZER

ABSTRACT This write up is a detail of the process and information of plan for the physical realization of the construction of the 1M3 mobile deep freezer. It is divided into chapters, which discussed extensively the practical refrigeration cycle with full attention given to design factors working principle and choice of material. The method used in fabrication, assembly and driving the safety requirement was not left out.  TABLE OF CONTENTTitle Page i...

ABSTRACTThe technical report presented below is based on the design of mechanism that can be used to open and shut the windows of mechanical engineering workshop from ground level .this mechanism was designed in order to improve safety and convince in their workshop .in the report, the design analysis were made and materials were selected based on operating conditions of each component.The material of the tilt and turn mechanism is cast iron while the material of the lever (handle) is stainle...

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.
