Development and Properties of Hybrid Composites
Published In: GJRE Part: C: Chemical Engineering Volume: 14 Issue: 3
The Flexural and tensile properties and Scanning electron Microscope analysis of Aramide/Onion/Glass fibers Reinforced Epoxy Hybrid composites were studied. The effect of alkali treatment of the Aramide/Onion/Glass fibers on these properties was also studied. These properties found to be higher when alkali treated glass fibers were used in the hybrid composites. The elimination of amorph...

Modeling and Output Feedback Distributed Control for an Absorption Packed Column
Published In: GJRE Part: C: Chemical Engineering Volume: 14 Issue: 3
This work consists of modeling, simulation and multiple models control of an industrial absorption packed column designated to remove CO2, from natural gas. The multiple models approach is an elegant way of turning nonlinear problems into linear ones. In this paper, we used the output feedback distributed control (ODC) coupled with local linearization of the model of the absorption packe...

Streptoquin and Septazole: Antibiotic Drugs as Corrosion Inhibitors for Copper in Aqueous Solutions
Published In: GJRE Part: C: Chemical Engineering Volume: 14 Issue: 2
The inhibiting effect of streptoquin and septazole towards the corrosion of the copper in 0.1M of HCl solution has been studied by potentiodynamic polarization measurements, electrochemical impedance spectroscopy (EIS) and Electrochemical frequency modulation technique (EFM). Potentiodynamic polarization curves indicted that these compounds behave as mixed-type inhibitors. These drugs we...

Removal of Phosphates and Chromates in a Multi-ion System
Published In: GJRE Part: C: Chemical Engineering Volume: 14 Issue: 2
Because industrialization is increasing the number of manufacturing facilities in traditionally rural agricultural areas globally, ground and surface waters with mixed fertilizer and industry contaminants must be considered. This work characterizes the effect of nitrates, phosphates, and chromates on the removal of phosphates and chromates from contaminated water via ion exchange with ca...

Models of Turbulent Transport and Transfer of Disperse Phase Mass in Liquids
Published In: GJRE Part: C: Chemical Engineering Volume: 14 Issue: 2
Using the theory of turbulent migration of particles and boundary layer models, expressions for calculation of particle transport coefficients and of mass transfer within the continuous phase are obtained. Various cases of turbulent direct flow of particles through the carrier turbulent medium are considered: smooth and rough channel; channel filled with fine random packing and apparatus...

Adsorption Kinetics of Sulfates by Anion Exchange Resin Containing Pristine Multiwalled Carbon Nano Tubes
Published In: GJRE Part: C: Chemical Engineering Volume: 14 Issue: 1
Since the documented discovery of carbon nanotubes (CNT) in 1991 by Iijima and the realization of their unique physical properties, including mechanical, thermal, and electrical, many investigators have endeavored to fabricate advanced CNT composite materials that exhibit one or more of these properties. The sulfates removal from synthetic water by High cross-linked polystyrene diviniyl ...

Experimental Determination of Bubble Size in Solution of Surfactants of the Bubble Column
Published In: GJRE Part: C: Chemical Engineering Volume: 14 Issue: 2
This paper focuses on the effect of surfactants on the bubble size. Bubble size in SDS/water system were investigated at various superficial gas velocities (0.13, 0.26 and 0.5 cm/s). On the other hands, Bubble diameter were determined for different values of SDS surfactant concentration. Surfactant concentration in water were 0.05, 0.02 and 0.1 vol.%. Tap water and aqueous solutions with...

Ni-NP/Ni Anodes with Varying Ni: NP Ratio Prepared by Electrodeposition for the Direct Methanol Fuel Cell
Published In: GJRE Part: C: Chemical Engineering Volume: 14 Issue: 1
Ni-NP/Ni anodes with varying Ni:NP ratio were prepared by electrodeposition of a thin Ni-NP (Nickel-Natural Phosphate) catalyst layer onto Ni plate for a direct methanol fuel cell (DMFC). The morphology and structure of the catalyst layers were analyzed by TEM and EDX. The catalyst coating layer shows an alloy character. The results show that these electrodes are very active for the meth...

Cleansing Activity of Polymeric Starch by Reducing the Environmental Hazards to Safe Green Chemistry
Published In: GJRE Part: C: Chemical Engineering Volume: 14 Issue: 1
The bio-degradable starch interaction with various surfactants has been studied for the investigation of ability and cleansing activity of starch-surfactant-water system. The surfactants investigated were sodium dodecyl sulphate, sodium octanoate, cetyltrimethyl ammonium bromide and tween-20. The DS of starch is 0.8 and the concentrations of starch were varied from 0.01 to 1% wt/v. The e...

Sensitivity of the Computational Domain Aspect Ratio for a Single Rising Bubble in a Hallimond Tube
Published In: GJRE Part: C: Chemical Engineering Volume: 14 Issue: 1
This paper presents how a single rising bubble experiment in the Hallimond Tube can be predicted using computational fluid dynamics model. The study is emphasized on the effect of aspect ratio of cylinder domain to the pressure coefficient and axial velocity around the bubble. A rigid sphere with the radius of 0.00575 m using flow velocity of 0.25 m/s is considered in this study. Numeric...

Condensate Recovery in a Plant and its Improvement
Published In: GJRE Part: C: Chemical Engineering Volume: 13 Issue: 2
Condensate recovery systems help us reduce three tangible costs of producing steam: • Fuel/energy costs • Boiler water make-up and sewage treatment • Boiler water chemical treatment The amount of steam generated and the condensate recovered was calculated for the plant. These values were used to find out the Condensate Recovery Factor (CRF) which...

Modifications in Molecular Parameters of Asphaltenes of Two Brazilian Oils for Action of Stockage Time
Published In: GJRE Part: C: Chemical Engineering Volume: 13 Issue: 2
In the extraction of the oil, it is mixed with water thus forming emulsions. The emulsions are found in almost all the stages of production and processing of the oil and in some cases is very difficult to be “brokenâ€Â. The presence of emulsifiers agents is one of the responsible factors for the stability of emulsions. Certain fractions of high point of boiling...

Exhaust Gas Simulation of Hydrogen–Ethanol Dual Fuel
Published In: GJRE Part: C: Chemical Engineering Volume: 13 Issue: 2
The drawback of lean operation with ethanol is a reduced power output. Lean operation of ethanol fuelled engines has additional drawbacks. Lean mixtures are hard to ignite, despite the mixture being above the low fire (point) limit of the fuel. This result in misfire, which increases unburned hydrocarbon emissions, reduces performance and wastes fuel. Hydrogen can be used in conjunction ...
