SOAP PRODUCTION

ABSTRACTThe aim of this seminar is soap production. Due to societal demands on cleaning agent to promote her hygienic conditions leads to research on how to produce soap which is one of the cleaning agent to meet the demands. Also in order to earn living through the out-come (financially) from the soap produced , many life can be enriched in the society. The process of soap production include”: cold process and hot process. The cold process of soap production requires measurement of lye a...

THE DESIGN OF A MODERN RAILWAY STATION

INTRODUCTIONThe word “Train” comes from the old French word trahiner, also from the latin word trahere which simply means “pull or draw”. It is a form of rail transport consisting of series of vehicles (coaches) propelled along a fixed rail track to transport goods or passengers. It can also be defined as a private or public conveyance system that travels along fixed routes and takes up set down passengers and their luggage at fixed points.A railway station also referred to as a train...

USE OF SOLAR ENERGY RATHER THAN ELECTRIC ENERGY TO CHARGE CELL PHONE

INTRODUCTIONIn today’s quest for electrical energy and increasing hazards in our environment, alternatives to the use of non – renewable and polluting fossil fuels have to be investigated. One such alternative is SOLAR ENERGY. Solar energy is quite simply, the energy produced directly from the sun and collected elsewhere, on earth. The sun creates its energy through a thermonuclear process that converts about 650,000,000 tons of hydrogen to helium every second. The process creates he...

CONSTRUCTION OF PORTABLE WHEEL-BARROW

ABSTRACTAfter detailed study on machines and levers, the construction work started as follows:-Making out, pattern development, cutting filling, drilling, machining, assembling, welding and finishing.  Detailed procedures carried out is located at the sequence of operation in subsequent pages.The machine has scale of 1:5 in all parts of its dimensions.  However, brief dimensions are given below:-Upper surface of bowl - 850mmInner surface of bowl - 335mmStan...

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...
