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...

Production of Biopesticide from Need Seed

Abstract Due to the toxic effects of chemical pesticide and other agro chemicals on human beings and livestock, residual toxicity, environmental problems, pest out-breaks and drastic effects on beneficial insects the use chemical pesticide and other agro chemicals are getting reduced /being banned globally. But Biopesticides that are extracted, for example, from neem seed can tackle these problems to make it more eco-friendly, economically viable and socially acceptable for the ...

THE USE OF SHEA BUTTER AS THE OIL BASE IN THE PREPARATION OF METHYL SALICYLATE (ANALGESIC) CREAMS

In the present study, an attempt was made to investigate the use of Shea butter as the oily base in the formulation of analgesic (Methyl salicylate) creams using hydrous wool fat base cream as standard. Methyl salicylate (The active ingredient), Bees wax, water and Shea butter obtained from local sources and refined were used separately on three different types on emulsifying agents namely cetrimide, polysorbate 80 and sodium lauryl sulphate, in the formulation of the analgesic cream. The st...

Influence of Composition on the Thermophysical Properties of LNG

The saturated liquid density deviations were compared using the PR, RSK (Advanced), AGA8, and GERG2008 EoSes. The bubble pressure deviations, saturated liquid densities, isobaric specific heat capacities, and enthalpy of vaporization were compared using the PR, RSK (Advanced) and GERG2008 EoSes. The GERG2008 EoS was used to analyse the effect of nitrogen and heavy alkanes on the thermophysical properties of LNG mixtures. Experimental density data was used to compare the accuracy of ...

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 ...
