Hydro geochemistry and Engineering Geology of Adeta Area, Ilorin, North-Central Nigeria.

ABSTRACTA study on hydrogeochemistry and quality of shallow water and engineering properties of soil around the Adeta area in Ilorin was carried out based on data obtained from the field and laboratory. Groundwater flow, descriptive, and multivariant statistical analyses, piper, stiff and durov diagrams, as well water quality indices were used to describe hydrochemistry and water quality suitability of the area. Grain-size distribution, Atterberg limit and permeability indices were used to de...

Optimization of the Operating Parameters for the Extractive Synthesis of Biolubricant from Sesame Seed Oil via Response Surface Methodology

This study examined the optimization of the transesterification reaction of sesame methyl esters (SMEs) with trimethylolpropane (TMP) to synthesise sesame biolubricant (SBL). Response surface methodology (RSM) using central composite design (CCD) was employed for the experimental design. Effects of temperature, mole ratio and reaction time on the yield of SBL were evaluated. The predicted yield after process optimization was found to agree satisfactorily with the experimen...

Synthesis and Tribological Evaluation of Sesame Oil-based Trimethylolpropane Ester

Synthesis of polyol ester as a novel biodegradable base stock from sesame seed oil for lubricant production was conducted via chemical transesterification of sesame methylester with trimethylolpropane (TMP) using calcium hydroxide catalyst. The reactions were carried out under varying temperatures (80 C160 C) and methyl esters to TMP mole ratios (3:1 to 7:1). Product’s analysis was performed using gas chromatography. Product’s physicochemical characteristics determi...

This modeling and simulation are applied Geldart B particle cla...

COVID-19 Virus Repellent Solution Based on the Liquid Electric Air Sanitization

Indubitably the most challenging coronavirus (Covid-19) outbreak, caused by SARS-CoV-2. With the number of Covid-19 cases now approaching millions globally so, for controlling the current infection rate, we have come up with this innovation of virus repellent electric liquid vaporizer means by vaporization of the solution which is the in-liquid form by means of electricity, which will enable the infectious virus and bacteria to be less effective also it will sometime kill the virus in a small...

Cashew Nut Shell Liquid, A Renewable and Reliable Petro-Chemical Feedstock

ABSTRACT The physical properties of CNSL extracted by pyrolysis was studied using standard procedures. The physical properties of the CNSL studied and results obtained compared with other extraction methods (hexane extracted and decarboxylated) from literature are moisture content 4.1%, (6.40%, 3.2%), specific gravity 0.943 (0.926, 0.926) viscosity 57cp (40cp, 358cp), pH 4.5 (4.5, 5.2) and the percent composition of the CNSL compared with those from literature are cardol 27% (30%, 31% ...

Modeling Bioremediation Of A Petroleum Contaminated Soil Enhanced With Npk Fertilizer And Animal/Plant Derived Organic Manure

ABSTRACT In this study, the potential effects of animal derived organic manure (cow dung, poultry droppings), saw dust and NPK fertilizer on the bioremediation of petroleum hydrocarbon contaminated soil was investigated. The rate of biodegradation was studied for the period of 10 weeks under laboratory conditions. The biodegradation data were fitted to eight models, four of which are based on microbial growth rate and the other four based on order of reaction. Results obtained show that...

Kinetic Modelling Of Enhanced Bioremediation Of Hydrocarbon Polluted Soil

ABSTRACT Remediation of hydrocarbon polluted soil applying all existing techniques can be slow, expensive and requires close monitoring. Bioremediation and phytoremediation augmented bioremediation have been used to treat petroleum contaminated soil and even the difficult poly aromatic hydrocarbon polluted soil which takes longer time. What has not been studied was the effect of heavy metals present in petroleum which slows down the substrate degradation by microorganisms. After the pri...

Development Of A Cathodic Protection System Using A Galvanic Anode Method

ABSTRACT The development of a Cathodic Protection System for a mild steel pipe using a magnesium anode was investigated. The pipe was externally coated with three layers of polykene tape wrapping and the soil resistivity was determined using the Wenner four pin method; a value of 2177Ωcm was obtained. The design parameters for the developed Cathodic Protection System were: total current of 0.0153mA; current density of 0.01mA/m 2 ; protection current of 0.0153mA; protection voltage o...

Development And Performance Evaluation Of A Tray Column Under Vertical And Tilt Conditions

ABSTRACT In this work, the operation and performance of a novel Separation Tray Column under Vertical and Tilt conditions is presented. The Tray Column used for the work is a Downcomerless liquid initiated and controlled Valve Tray with capacity to shut portions of the tray lacking liquid at any time. To evaluate the mass transfer performance of this column, an oxidation experiment was conducted at 300C and the percentage of Fe (II) oxidised to Fe (III) from contaminated water by air wa...

Determination Of Surface Charge Density Of Α-Alumina By Acid - Base Titration

ABSTRACT. The surface charge density (σo) of colloidal alpha-alumina suspended in various 1:1 electrolytes was measured using acid-base titration. An auto titrator capable of dispensing accurately 25 ± 0.1 µL of titrant was used. The pH and temperature in the titration cell were monitored using single-junction electrodes and platinum resistance thermometers, respectively. A constant supply of nitrogen gas in the cell was used to maintain inert conditions. The whole set-up was interface...

Optimizing The Conditions And Processes For The Production Of Protein Nutrient From Parkia Biglobosa Seeds

ABSTRACTAfrican Locust Bean (Parkia biglobosa) seeds known as ‘Iyere’ in Yoruba language were fermented aerobically and anaerobically at 40, 50, 60 and 70 °С for five days (120 hours) with the aid of two starter cultures - Bacillus Subtilis and Saccharomyces Cerevisiae to a vegetable protein based food condiment known as ‘Iru’. The Fermenter was fabricated with galvanized iron, thus getting rid of the unhygienic methods of producing it locally. Samples were taken every day (24 hours...
