Design of a Biogas Plant

Note: This work contains only the schematic diagram/design of a biogas plantBiogas typically refers to a mixture of gases produced by the breakdown of organic matter in the absence of oxygen. Biogas can be produced from regionally available raw materials such as recycled waste. It is a renewable energy source and in many cases exerts a very small carbon footprint.Biogas is produced by anaerobic digestion with anaerobic bacteria or fermentation of biodegradable materials such as manure, s...

THE BLEACHING OF PALM OIL USING ACTIVATED CHARCOAL

ABSTRACTThis project work is on the bleaching of palm oil using activated charcoal.The charcoal used for this work was made from pieces of animal bone by carbonization method.  It was then activated into two different samples.  Firstly, the basic sample was activated using anaphoric acid (H2 s04) while the other was activated by just heating as a control for the experiment; both at a constant temperature of 5000c and approximate time of 2hours.They were both size reduced into fines ...

COMPARATIVE ANALYSIS OF THE STRENGTH OF CONCRETE MADE FROM VARIOUS AGGREGATE

INTRODUCTIONThis work was obligated to present in one. The fundamental and practical information in the filed of the comparative analysis of the strength of concrete made from various aggregate which may be useful to people involve in civil and structural engineering and particularly, those that found pleasure in the design and related structure.Due to high cost of sand in the market the  comparative analysis of strength of concrete  made from various aggregate play an important rol...

CONSTRUCTION OF A STELL CUPBOARD

ABSTRACT The aim of this project was to construct a steel cupboard in order to help us acquire the knowledge of fabrication of a modern cupboard and the essence of it. Also to enable us (the students of chemical Engineering) to know how to construct as future engineers. The construction of steel cupboard was done using a square pipe of 1.5mm thickness and the mild steel having a thickness of 1.5mm. it was mark out cut, welded, filled and painted. The  cupboard has length and height of ...

DESIGN AND CONSTRUCTION OF FOUR-WAY TRAFFIC LIGHT

ABSTRACTThe project “microcontroller based intelligent traffic light system with automatic street light and warning light” was designed to tackle the traffic issues in the country so as to establish automatic traffic control and monitoring system with near perfection. The project intelligent traffic light with automatic street light and warning light is a complex microcontroller based project that was designed to control traffic on a four way road network.The system is embedded with ...

PRODUCTION OF DOMESTIC POWDER

ABSTRACTThis research project is aimed at producing domestic powder and consequently, three different types of powder were produced, namely, simple face powder (pan-cake), medicated/Antiseptic powder (dristing   powder).During the various production Talcum, Zinc-oxide, Perfume, Menthol, Tragasan 300 DP (Triclosan), Mineral oil and colour (brown) were the materials used in the production of different powders. And equipment and apparatus used for production  of the three different pow...

CONSTRUCTION OF A HYDROCYCLONE

ABSTRACTThe hydrocyclone is a separating device used for the separation of dust particles from air, which has no moving component parts. This mechanism can also be defined as a system of winds circulating about a center of relatively low barometric pressure and on the earths surface, blowing inward in spiral form.This project is constructed for the separation of liquid – liquid and solid – liquid mixture, like air and dust mixture, dust and liquid drop. This equipment is constructed to se...

CONSTRUCTION OF WATER STORAGE TANK (2000 LITRES)

ABSTRACTThe 20000 liters storage tank was constructed for effective storage and conservation of third with three (3) mild steel sheet of 14 gauge (2mm) thickness. The construction started by marketing out 1½ (One and half) mild steel of 2440 Mm by 113Mmusing metal meter rule and critter the already market out dimension underwent cutting with a backsaw and after marking out and cutting operation of the cylindrical part it under went fording, using hammer and folding machine, and finally ...

REFINING OF VEGETABLE OIL WITH ENUGU COAL

ABSTRACTThis project was carried out using acid activated coal from Enugu coal and the production of ve4getablew oil was monitored using spectrophotometer to measure the absorbance. It was also perform to check the suitability of activated Enugu coal as a bleaching agent for palm oil.The Enugu coal samples were collected, size reduced, carbonized and activated with acid (phosphoric Acid) before being used for the bleaching process. The bleaching process lasted for 40minutes and it was absorbe...

CONSTRUCTION OF 500W12VINVERTER CHARGER

ABSTRACT An inverter is a system which is capable of converting DC voltage from a battery into AC voltage. The Inverter constructed converts 12V dc to 220V Ac. It consists of an oscillator section using 8V dc to produce 50Hz sine wave. The sine wave is amplified by Tip 41 and used to drive IRPF 250 MOSFET power transistors capable of delivering 500W norminally.The mosfet switches the 12V dc across the high current transformer which then produces the Ac at its output. The output of the tr...

CONSTRUCTION OF A MICROCONTROLLER BASED SECURITY DOOR USING SMART CARD

ABSTRACTThis project shows the construction of a microcontroller based security door using smart card. It is aimed towards programming the microcontroller to control the hardware in sliding door. The system consists of a microcontroller 89S52 which sends a signal to the multiplexers on insertion of the smart card in the card slot. The multiplexers consist of ICS which prompts for a display of the identity of the card user in the liquid crystal display (LCD). The LCD displays the status of the...

CONSTRUCTION OF A MICROCONTROLLER BASED GATE

ABSTRACTMicrocontroller based automate controller is a project design of a system that is used in operating a gate automatically. The system opens the gate automatically when a human being or car is about to enter a compound or exit a compound. The system works by sensing the light rays from the head lamp of the vehicle. The light ray is sensed and signal is used in operating the gate. Different blocks of circuit are put together to ensure that the system works perfectly as desired. The block...

CONSTRUCTION OF STEEL CUPBOARD

ABSTRACT A workshop cupboard is a facility designed from mild steel for the storage of various materials, like book material and non-book materials e.g. workshop tools, labouratory wares and reagents, etc; after operations in a chemical labouratory, mechanical workshop, or else where. The construction of a workshop cupboard requires the consideration of lots of characteristics of the materials, which are used for the construction, such as physical and mechanical; chemical properties, servic...

CONSTRUCTION OF METAL DETECTOR

ABSTRACTMetal detectors are electronics sensors that indicate the presence of metallic object without making physical contact with object. They are effective and useful security tools employed in strategic places such as airport, bank, stadiums, government houses and also in production industries to detect presence of metallic object on person luaggages, consignments foods, drugs garments etc. The study present a metal detector comprising a radio frequency oscillator, demodulating unit, trigg...

CONSTRUCTION OF A GSM BASED HOME AUTOMATION USING AVR

ABSTRACTWith advancement of technology things are becoming simpler and easier for us. Automatic systems are being preferred over manual system. The purpose of this project is to design and construct A GSM based home automation using AVR. Using GSM networks, in this project a home power control system has been proposed that will act as an embedded system which can monitor and control appliances and other devices locally using built-in input and output peripherals.
