Design of Distillation Column

Azeotropic distillation of ethanol-water mixture is accomplished by adding a volatile thirdcomponent to the liquid which changes the volatility of one of the two components more than theother so the components are separated by distillation. The two components to be separated oftenhave similar boiling point components which do or do not azeotrope in the binary mixture, butsometimes there are components which do azeotrope despite having vastly different boiling points.It is likely that in some ...

Design, Fabrication, and Performance Evaluation of a Double Effect Evaporator

This project study was aimed at designing, fabricating, and evaluating the performance of a double effect evaporator, which was used to evaporate sugar syrup to be used for students’ demonstration. During the course of the study, the methods that were used comprised of the material balances, energy balances, and determination of the component parts of the evaporator. The results from the study included the overall material in the evaporator’s system, the material balance for each effect, ...

CHARACTERIZATION OF NON-EDIBLE OIL FROM WASTE PLANT MATERIALS FOR PRODUCING BIODIESEL

ABSTRACTOil obtained from orange peels and velvet tamarind nut by solvent extraction (n-hexane and acetone) using the soxhlet extractor were investigated as feedstock’s to determine some of the suitable parameters such as iodine value, saponification value, specific gravity, density, acid value and free fatty acid value, and their percentage yield that are suitable for biodiesel production. The density of orange and tamarind oil were found to be 0.9326g/cm3 and 0.8541g/cm3 respectively, the...

PLANT DESIGN OF 250,000KG/YR OF LINDANE

Studies on Microwave-Assisted Extraction of Drumstick Tree (Moringa oleifera) Seed Oil

ABSTRACT The need for effective and efficient means of oil extraction has been a concern in recent time. Hence, this study aimed at the oil extraction from Moringa oleifera seeds using the Microwave-Assisted extraction method. The extraction process was modeled using Response Surface Methodology (RSM). Also, the evaluation of Moringa oleifera oil as a good feedstock for biodiesel production was carried out. Oil was extracted from the M. oleifera seed kernel using Microwave-Ass...

Production of Bioethanol from Cassava Using a Hybrid of Saccharomyces Cerevisiae and Saccharomyces Paradoxus

ABSTRACT Cassava  is  considered  as  a  potential  source  for  the  commercial  production  of  bioethanol because of its availability and low market price. It can be used as a basic source to support large-scale biological  production of  bioethanol using  microbial amylases. With  the progression  and advancement in enzymology, starch liquefying and saccharifying enzymes are preferred for the convers...

Synergistic effect of Datura stramonium leaves extract - Zn2+ on the corrosion inhibition of mild steel in well water

This study covers the evaluation of the synergistic effect of Datura stramonium leaves extract-Zn2+ in the corrosion inhibition of mild steel in well water. Varying effects of different concentrations of the extract and 5ppm of Zn2+ on the corrosion inhibition of the mild steel specimen will be determined in order to ascertain the synergistic effect that exists between the leaf extract and Zn2+ 

Kinetic Study and Optimization of Selected Factors Affecting Corrosion Using RSM

ABSTRACT   The kinetics and optimization of inhibitive action of leaves extract of pawpaw, Azadirachta indica (neem tree) and bitter leaf on corrosion of mild steel in acidic medium was studied by weight loss technique using central composite design of response surface methodology for optimization. The metal was analyzed using Atomic Absorption Spectrophotometer to determine its elemental compositions. The extract was obtained by liquid extraction using ethanol and was analyz...

Design and Fabrication of Sedimentation Test Rig

ABSTRACTNowadays, the destruction and pollution of humane environment has produced an ever growing awareness worldwide of the need for more effective sedimentation processes. The main aim of this project was to design and fabricate an experimental sedimentation rig with the objective to determine the rate of settling against time using calcium carbonate as a test sample.The rig consists mainly of the cylindrical tank, valves, motor, stirrer, and the sight glass. For the test run, 82 litres of...

Catalytic conversion of polyethylene to liquid fuel and solid wax using the (CaOH2)

ABSTRACTThe objective of the work is the catalytic conversion of waste plastics into fuel oil and solid wax using Ca(OH)2 and the design of pyrolysis reactor. Plastic wastes such as, polypropylene, low density polyethylene, high density polyethylene, polystyrene are the most frequently used in everyday activities and disposed of to the environment after service. There are a number of methods by which plastic wastes can be managed such as incineration, recycling, land filling, thermal and cata...

Health Effects of Air Pollution in Oleh Town, Delta State

The spread of pollutant in an area is partly a function of wood burning in local kitchens by the population of the area. This pollution generated through combustion of wood  fuels presents difficult environmental challenges to societies as it could degrade the environment and affect human health and quality of life. Wood burning emissions are major contributors to air pollution in rural areas as they contain harmful gases. The level of carbon monoxide in the air in two location in oleh town ...

INVESTIGATION INTO THE EFFECTS OF TEMPERATURE ON ITAKPE IRON CONCENTRATE MAGNETO VISCOUS FLUIDS

ABSTRACTThis research work show cases the potentials of Itakpe Iron concentrate for Magneto-rhelogical abilities. The concentrate was first ball milled to size reduce it then subjected to low magnetic strength from magnetic bits in-situ the magnetic fluid.It was determined that temperature affected the fluid inversely, as temperature increased at the shear rates from the viscometer and Newtonian viscosity calculated reduced, giving a negative relationship between temperature and Newtonian vis...

Extraction and Phytochemical Analysis of Oil from Neem and Morning Oleifera Seeds and Leaves

ABSTRACTPhytochemicals are chemical compounds produced by plants, generally to help them thrive or thwart competitors, predators, or pathogens. These chemicals are produced by plants through primary or secondary metabolism (Breslin A,2017) . These work was done to determining the presence of phytochemicals such as Tannins, Saponin, Alkaloids, Anthraquinone, Phlobatannins, Flavonoids and  Cardiac Glycosides (e.g Steroidal Ring or Terpenoids and cardenolide) from oil extracted from mo...
