Enhancing the Performance of Ubakala Clay for Use as Drilling Mud

ABSTRACT This project is on the enhancement of the performance of an Ubakala clay sample for use as drilling mud. A sample of Nigerian clay (Ubakala clay) was used for the project. The clay sample was collected in a raw state, processed and experiments conducted on viscosity which is a very important property of drilling mud. Various concentrations of sodium carbonate were mixed with the clay sample and experiments were conduc...

The Solution Behaviour of Butyric Acid-Water-Toluene System at 30oC and 1 Atmosphere

ABSTRACT Liquid-Liquid Equilibrium (LLE) data of Butyric acid-Water-Toluene ternary system were determined experimentally at a temperature of 30oC and 1 atmosphere. The complete phase diagram was obtained by determining the solubility curve and the tie-lines. The reliability of the experimental tie-line data was ascertained by using the Othmer and Tobias plot. Also, the UNIFAC model equations were used to estimate the activity coefficients of the ...

DESIGN, MODELLING AND SIMULATION OF CRUDE OIL DISTILLATION PLANT

ABSTRACT This research presents a flexible design model and robust algorithm for simulation of a crude oil plant which consists of a main column with several side strippers and pumparounds. The model is developed in commercial software HYSYS, Pro/II and Aspen Plus, in order to evaluate the performance of the simulation of these models on personal computers. The development of the mathematical model of the equipments of the unit is based on the relations that a...

Multicomponent Adsorption Models and the Kinetics of Deodourisation of Commercial DPK

ABSTRACT The Multicomponent adsorption models and kinetics of deodorization of commercial kerosene (DPK) using conventional and non-conventional adsorbents have been investigated. The adsorbents used were bone char, limestone, silica gel and clay. The influence of contact time, adsorbent mass, pH, temperature, and adsorbent particle size on the rate percent aromatic and sulphur removal was evaluated. The experimental results were fitted to the Langmuir, Freundl...

Design of a Plant for the Production of Potable Water from Sea Water (Desalination Process)

ABSTRACT The Mass and Energy Balance requirements for the production of potable water quality starting from sea water are presented. On the basis of economics of the process, a twenty (20) stage flash (MSF) plant analysis is presented for the production of 1,500m3 of potable water from sea water as required. The overall analysis seems attractive. The design of the nine pre treatment units and product storage tank are also presented. The qua...

Evaluation of the Application of Wastewater and Bioventing System for the Treatment of Crude Oil Contaminated Soils

Environmental pollution is a form of land degradation which has contributed immensely to the reduction of available arable lands and could lead to the total annihilation of the ecosystem if not effectively mitigated. Bioremediation technology offers a biological means which provide an eco-friendly and cost-effective approach for soil remediation in contrast to physicochemical methods. This study aims to evaluate the application of wastewaters and air-injection ...

Evaluation of Industrial and Municipal Wastewaters as Bio-Stimulants for the Treatment of Crude oil Contaminated Soils

The prevalence and high rate of soil contamination have contributed immensely to the reduction of arable lands which might lead to the total annihilation of the ecosystem if not mitigated. Bioremediation employs microorganisms that offer a sustainable approach for the remediation of contaminated soils. This study focus on the evaluation of industrial (brewery) and municipal effluents for the treatment of crude oil-contaminated soil. A microcosm containing 1kg of crude oil-contaminated soil ...

Biofuel Production Potential of Anacardium Occidentale (Cashew)

ABSTRACTMature and ripe cashew fruits were harvested, washed and the apples separated from the nuts. The apples were crushed and the juice extracted, sieved and treated with potassium metabisulphite, to check the activities of undesireable microorganisms, before fermentation. A 3-spatula full of true wine yeast, Saccharomyces cerevisiae var. ellipsoideus, was rehydrated and inoculated into a 2.5-liter part of the juice and allowed for 5 days in a room temperature of 32.50C to ferment. A...

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 ...

VAPOR–LIQUID EQUILIBRIA OF MIXTURES CONTAINING n-DECANE, CARBON DIOXIDE AND ARGON USING MOLECULAR SIMULATION TECHNIQUES (GIBBS ENSEMBLE MONTE CARLO SIMULATION)

 Abstract The CO2–hydrocarbons systems is common in oil and gas industry as a geological fluid. CO2 plays a vital role in biological processes namely photosynthesis, respiration, and actively participates in the carbon cycle. However, the time gradient of carbon dioxide concentration in the atmosphere has become a major global concern. The environmental challenges associated with the control and management of anthropogenic emissions of greenhouse gases have been the focal po...

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...

VALORIZATION OF BIO-PLASTIC (PHA) FROM WASTEWATER AND CIRCULAR ECONOMY

ABSTRACT Circular economy requires sustainable supply of raw materials to industries. Social and economic networks are needed in order to develop circular economies that would drive value chains in renewable resource processing from wastewater into renewable bioplastic products. Current plastic is non-biodegraded which can cause harm to our environment. A pilot scale investigation was carried-out so as to evaluate the feasibility of producing value-added bioplastic from wastewat...
