Isotherms of adsorption of crystal violet (CV) on activated carbon (AC) synthesized from rice husk are presented herewith to elucidate the mechanism of the adsorption process of crystal violet dye contaminated water on rice husk activated carbon. AC was synthesized from rice husk via a phosphoric acid activating agent at low temperatures. Langmuir, Freundlich, Temkin and Dubinin–Radushkevich (D-R) isotherm studies were employed. The mean square values for Langmuir, Freundlich, Temkin and D-R models were 0.98, 0.91, 0.94, and 0.63, respectively. Analysis of the isotherms of the adsorption of crystal violet sorbate on the synthesized rice husk sorbent suggested that the adsorption process procee...

In order to overcome this problem and add value to clay minerals, beneficiation process is an indispensable solution. This study investigates effect of wet beneficiation process on the characteristics of a local clay mined from Getso village of Kano State, Nigeria. Mineralogical characterization of the clay was carried out using X-ray diffraction (XRD) analyzer. Chemical characterization of the clay was carried out using X-ray fluorescence analyzer. Physicochemical characterization of the clay was carried out using pH meter and density analysis conducted using density bottle. XRD analysis of Getso clay showed that the raw clay had 8 wt% kaolinite and 51% quartz. Wet beneficiation resulted into 53% improvement of the kaolinite content and 47% reduction of quartz impurity. The XRF analysis has shown that silica-alumina ratio of the raw Getso cla...

Model equations for prediction of process parameters of reverse osmosis for desalination of seawa... more Model equations for prediction of process parameters of reverse osmosis for desalination of seawater were developed via mathematical derivation from basic equations for the reverse osmosis process. A model equation relating the interfacial solute concentration () with the process pressure difference () was developed. Taking the of reverse osmosis as the basic independent variable, further model equations relating other process parameters such as the solute concentration polarity , water flux , osmotic pressure , water output rate (q), power density (Pd) and specific energy consumption (SEC) were developed. Simulation of hypothetical reverse osmosis data using Microsoft Excel Worksheet and Microsoft Windows 10 on a 64-bit operating system was carried out. Simulation results showed that the optimum fluid bulk concentration was = 0.0004 mole/cm3. The optimum rate of increase in the solute rejection factor per unit rise in ΔP was 0.45%. The optimum solute rejection factor was 97.6%. The...

Mineralogical characterization of the clay was carried out using X-ray diffraction analyzer. Chemical characterization of the clay was carried out using X-ray fluorescence analyzer and the pH analysis of the clay was carried out using pH meter. The mineralogical analysis revealed that the clay was majorly a dolomite mineral having 72% dolomite. The impurities present are 18% cristobalite, 4.1% garnet, 5% calcite and 1% quicklime. The pH analysis of the clay revealed that the clay was acidic having average pH value of 3.9. The pH determined for the 1:1, 1:2, 1:4, 1:8 and 1:10 samples were 3.61, 3.85, 3.85, 4.05 and 4.09, respectively.

Langmuir and Freundlich isotherm models were employed for the study. Varying ratios of 1:1, 0.75:1, 0.5:1, and 0.25:1 activating agent to cassava peel were used for the formulation of the Activated Carbon. The Freundlich R 2 value for the 1:1, 0.75:1, 0.5:1, and 0.25:1 formulations was 0.822, 0.979, 0.971 and 0.974, respectively. While the Langmuir R 2 value for the 1:1, 0.75:1, 0.5:1, and 0.25:1 formulations was 0.021, 0.139, 0.001 and 0.894, respectively. Keywords: Activated carbon, cassava peel, adsorption, isotherm * Author for Correspondence E-mail: nusdeen@yahoo.co.uk INTRODUCTION Cassava is the third-largest source of food carbohydrates in the tropics, after rice and maize, it is a major staple food in the developing world, providing a basic diet for over half a billion people [1]. More than 228 million tons of cassava was produced worldwide in 2007...

The raw clays were mined and beneficiated using the wet beneficiation method. The raw and beneficiated clay samples were characterized using XRD and XRF techniques, the specific density and pH values of the clays were also determined. The characterization results showed that the clays developed higher purity after beneficiation, as reflected by the decrease in organic impurities in the form of carbon and graphite and reduction in quartz and soluble salts. The raw Pindiga clay sample had high iron oxide content up to 26.54 wt% which reduced to 24.15 wt% after beneficiation, while the raw Gambe clay contained 11.87 wt% iron oxide which reduced to 4.96 wt% after beneficiation. Also, the raw Gambe clay sample had high calcium oxide content up to 20.0 wt% which reduced to 18.5 wt% after beneficiation, while the raw Pindiga clay con...

Local Ririwai biotite mined in Doguwa Local Government Area of Kano State was used as a weighting agent in drilling mud formulation. Scanning Electron Microscopy (SEM) characterization, X-ray Diffraction (XRD) and Electron Dispersion X-ray (EDX) analysis of the Ririwai biotite were carried out. Water-based drilling mud was prepared using commercial bentonite according to the API 13A Standard. Effect of gradual addition of Ririwai weighting agent; 0 – 100 wt%, on the yield point of the formulated drilling mud was studied. XRD analysis showed that the dominant mineral phase in the material was biotite. Morphological analysis carried out showed that the Ririwai biotite had a sheet-like morphology while the commercial bentonite had clumpy morphology. The estimated average particle sizes were 60 and 25 μm for the Ririwai biotite and commercial...

The primary objectives of this work were to analyze the system components separately and to identify and quantify the sites having largest energy and exergy losses. The performance of the plant was estimated by a component wise simulation using Aspen Hysys software and a detailed break-up of energy and exergy losses for the considered plant has been presented. The ideal work was calculated to be (-74.169 MW) which characterized the system as work producing. Energy losses mainly occurred in the fractionator column where 46.6MW is lost to the environment while only 3.69, 1.77 and 0.68 MW was lost from the condensers, other equipment and absorbers respectively. The percentage exergy and second law efficiencies of the system was found to be 61.20 and 24.77 %.

Mineralogical characterization was carried out using X-ray diffraction (XRD). The specific gravity of the material was determined using density bottle apparatus. Water-based drilling mud was prepared using commercial bentonite according to the API 13A Standard. Effect of gradual addition of Ririwai weighting agent; 0 – 100 wt%, on the mud density and rheological property were studied. XRD analysis showed that the material was biotite mineral. The specific gravity of the Ririwai biotite was determined as 2.40. The optimum composition of the drilling mud was 40 wt% Ririwai biotite as weighting agent. The optimum composition gave mud density and plastic viscosity of 9.0 lb/gal and 3 cp respectively. At the optimum composition, the weighting agent increased the mud density by 2.3% while the plastic viscosity decreased by 50%.
