The 15th of October has been decreed a day to focus on germs specifically. It’s the germs on our hand that are in the firing line .The world health organization estimates that 3.5 million children die from diarrhea and lower respiratory tract infections each year. That’s why global hand washing day was decreed. Sanitation of hand has... Continue Reading

Engine oils are made from crude oil and its derivatives by mixing of certain other chemicals (additives) for improving their certain properties. Lubricating oil is used to lubricate moving parts of engine, reducing friction, protecting against wear, removing contaminants from the engine, act as a cleaning agent, and act as an anti corrosion and...

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... Continue Reading

The 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... Continue Reading

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... Continue Reading

Azeotropic distillation of ethanol-water mixture is accomplished by adding a volatile third component to the liquid which changes the volatility of one of the two components more than the other so the components are separated by distillation. The two components to be separated often have similar boiling point components which do or do not... Continue Reading

 The purpose of this study is the preparation of activated carbon using a suitable industrial sludge. The characterization of two types of industrial sludges showed that paper sludge was a better option over rice husk. The activated carbon produced from pyrolysis of paper mill sludge was chemically activated with various activating... Continue Reading

The project research entailed the production of high quality sealant  incorporating a local raw material for sealing holes and gaps in various materials  like metal and plastic.
