Computer Aided Design for Spray Driers
Authors: A. AI-Hemiri Adil , N. Saleh Saad 
Published: May 2023

The aim of this work is to develop an axi-symmetric two dimensional model based on a coupled simplified computational fluid dynamics (CFD) and Lagrangian method to predict the air flow patterns and drying of particles. Then using this predictive tool to design more efficient spray dryers. The approach to this is to model what particles experience in the drying chamber with respect to air temperature and humidity. These histories can be obtained by combining the particles trajectories with the air temperature/humidity pattern in the spray dryer. Results are presented and discussed in terms of the air velocity, temperature, and humidity profiles within the chambers and compared for drying of a 42.5% solids solution in a spray chamber 2.22m in diameter with a cylindrical top section 2.00m high and a bottom cone section 1.725m high.

Published: May 2023

This investigation is a study of the length of time where drops can exist at an oil-water interface before coalescence take place with a bulk of the same phase as the drops. Many factors affecting the time of coalescence were studied in is investigation which included: dispersed phase flow rate, continuous phase height, hole size in distributor, density difference between phases, and viscosity ratio of oil/water systems, employing three liquid/liquid systems; kerosene/water, gasoil/water, and hexane/water. Higher value of coalescence time was 8.26 s at 0.7ml/ s flow rate, 30cm height and 7mm diameter of hole for gas oil/water system, and lower value was 0.5s at 0.3ml/s flow rate, 10 cm height and 3mm diameter of hole for hexane/water system. It is observed that time of coalescence increased with increase in the dispersed phase flow rate, continuous phase height, hole size in distributor, and viscosity ratio of oil/water system. The results have been analyzed by dimensional and statistical analysis, and a correlation was developed relating coalescence time with the operating/actors and the physical properties of the three oil/water systems.

Avery large numbers of articles are made by powder metallurgical methods using electrolytically reduced metal powders. Iron powder is one of these powders which play an important role in this field. Its preparation by electrolytic method is economic in comparison with the traditional methods (Atomization and carbonyl processes).
An electrochemical cell consisting of two electrodes (stainless steel cathode and iron anode, 99.9%) was used to study the electrolytic preparation of iron powder with particle size less than 106µm directly as powde1y form. Ferrous sulphate electrolyte was used containing sodium chloride as a stabilizing agent. The produced powder was thoroughly washed with an acidified distilled water and absolute ethanol, then dried under an inert atmosphere at 80°C, and classified by screening. Samples of prepared powder were taken to determine their purity by atomic absorption. The effects of current density, metal ion concentration, sodium chloride concentration, PH, and electrolysis time on the weight percent of iron powder less than (106µm), yield and current efficiency were studied.
It was found that an iron powder with particle size less than 106µm can be prepared at a weight percent of iron powder less than I06µm (89.7%) and current efficiency of 71% using cathodic current density of 0.1 A/cm3 and electrolysis time equal to 1 hr. The prepared powder having an apparent density of (3.24 gm/cm3 and real density of 7.39 gm/cm3 with specific surface area of 238 X 103 cm2/gm. Its average particle size was 75 pm and its purity was 99.14%

Authors: A. Al-Hemiri Adil , Y. Al-Kaisy Farah 
Published: May 2023

This work was conducted to determine the volumetric mass transfer coefficient (Ky.a) infixed bed adsorption using hexane-benzene mixture by adsorption onto a fixed bed of white silica gel. Benzene concentration was measured by gas chromatography. The effect of feed flow rate and initial concentration of benzene in hexane-benzene mixture on the volumetric mass transfer coefficient and on the adsorption capacity of silica gel was investigated.
In general, the volumetric mass transfer coefficient increases with increasing hexane flow rate, and with increasing initial concentration of benzene in the mixture. The ultimate value of (Ky.a) was at 53 ml/min of hexane flow rate with benzene initial concentration of (6.53 wt. %), and it was (99.4 kg/m3.s).
The adsorptive capacity of silica gel increases with decreasing hexane flow rate, as with increasing initial concentration of benzene in the mixture. The best adsorptive capacity of the imported silica gel (100 g of imported silica gel yielded 120 ml of benzene-free effluent) was achieved with the grade (1.18-5 mm) in size at a hexane flow rate 15 ml/min.

Published: May 2023

The bauxite produced from Al-Ga 'ara area in Al-Enbar containing 50.4 wt. percentages Al2O3 was used for a- alumina production.
For α-alumina production bauxite was mixed with calcium carbonate in a ratio 1:3 and the mixture was burned at temperature range 1l 50-l350°C, cooled to 500°C; crushed and ground. The powder produced treated then with 6% sodium carbonate solution using different temperature (60-100°C) for fifteen minutes. After filtration, the produced sodium alurninate solution was reacted with 2% of calcium hydroxide at 98°C for thirty minutes. The filtrate was carbonated with purified C02 gas at 70°C for different times (30-180 min) and different flow rates (20-80 cm3/min).
Alumina was precipitated as hydrate, then washed with water, dried at 110°C, and calcined at 1200°C. The produced α­ Al2O3 was identified by X-ray diffraction.

Authors: J. M. Slaiman Qasim , O. Hasan Basim , A. Mahmood Hussein 
Published: May 2023

The corrosion of carbon steel in single phase (water with 0.1N NaCl ) and two immiscible phases (kerosene-water) using turbulently agitated system is investigated. The experiments are carried out for Reynolds number (Re) range of 38000 to 95000 corresponding to rotational velocities from 600 to 1400 rpm using circular disk turbine agitator at 40 0C. In two-phase system test runs are carried out in aqueous phase (water) concentrations of 1 % vol., 5 % vol., 8% vol., and 16% vol. mixed with kerosene at various Re. The effect of Reynolds number (Re), percent of dispersed phase, dispersed drops diameter, and number of drops per unit volume on the corrosion rate is investigated and discussed. Test runs are carried out using two types of inhibitors: sodium nitrite of concentrations 20, 40, and 60 ppm and sodium hexapolyphosphate of concentrations 485, 970, and 1940 ppm in a solution containing 8 % vol. aqueous phase (water) mixed with kerosene (continuous phase) at 40 °C for the whole range of Re. It was found that increasing Re increases the corrosion rate and the presence of water enhances the corrosion rate by increasing the solution electrical conductivity. For two phase solution containing 8% vol. and 16% vol. of water the corrosion rate was higher than single phase (100 % vol. water). The main parameters that play the major role in determining the corrosion rate in two phase were concentration of oxygen, solution electrical conductivity, and the interfacial area between the two phases (dispersed and continuous). Sodium nitrite and sodium hexapolyphosphate were found to be efficient inhibitors in two phase solutionfor the investigated range of Re.
Removal of Emulsified Paraffine from Water: Effect of Bubble Size and Particle Size on Kinetic of Flotation
Authors: A. Mohammed Ahmed 
Published: May 2023

This paper studied kinetics of flotation of emulsified paraffine in water in bubble column with sodium .dodecylsulphate as a collector agent. The effects of oil drops and air bubble diameters on the flotation rate constant were studied. The removal rate for each oil drop size was first order with respect to oil drop concentration. An experimental procedure permitting determination of the first order rate constants for removal due to bubble/drop interaction was developed, decreasing bubble diameter by adding NaCl and increasing oil drop diameter increased the rate constants. A comparison between the experimental and theoretical rate constants showed that the predicted mechanism of oil-droplet removed by bubbles less than 1.8 mm diameter is one of hydrodynamics capture in the wake behind the rising bubbles.

Published: May 2023

The study of the dynamic behavior of packed distillation column was studied by frequency response analysis using Matlab program. A packed distillation column (80 mm diameter) (2000 mm height) filled with glass packing (Raschig Rings 10mm), packing height (1500 mm) has been modified for separation of methanol-water mixture (60 vol%). The column dynamic behavior was studied experimentally under different step changes in, feed rate (±30%), reflux rate (±22%), and reboiler heat duty (±150%), the top and bottom concentration of methanol were measured. A frequency response analysis for the above step response was carried out using Bode diagram, the log modulus and the phase angle were used to analyze the process model. A Matlab program was used to study the dynamic model for continuous packed distillation to predict the transient response to a step change in feed rate, reflux rate and reboiler heat duty. It also used to find the frequency response analysis using experimental data and the results were compared with A RX(Auto Recursive) model, then the plot of Bode diagram was carried. Finally the transfer function to step change in feed rate was found and represented by second order as shown in equation below.
For reflux rate change, it was found that for the top concentration, it can be represented by first order (lead - lag system).
Finally a comparison between the experimental and theoretical response curves were made, it was found that the model obtained from Matlab program (Bode diagram) gave a good agreement with experimental data while the model obtained using process reaction curve method shows a deviation between the theoretical and experimental data.

Authors: Yasseen Hadeel A. , Hamoudi Salim R. 
Published: May 2023

Background: The coronary atherosclerosis received a great concern from the clinical aspect, but its pathological aspect is deficient in Iraq.
Objectives: To find a correlation between the type of the lesions that were grossly identified and their corresponding microscopical grades and Studying the effect of remodeling on preservation of the luminal area, 3) demonstrate the endothelial dysfunction in atherosclerosis.
Methods: fifty cases were gathered from the Medico-legal institute in Baghdad during the period from January to July 2004.The left anterior descending (LAD), left circumflex (LCX) and right coronary artery (RCA) from 50 postmortem cases were biopsied. Cryosectioning and staining with Oil-red O stain were done for twenty five specimens, then all the cases were embedded in paraffin blocks, and stained for hematoxylin and eosin (H&E) stain, Verhoff Van Gieson (VVG), twenty cases were stained with CD34 immunohistochemical marker. Cases were graded according to the American Heart Association (AHA) classification system.
Results: Seventy three per cent of grossly normal specimens were microscopically normal, while grossly flat fatty streaks correspond in 83% of cases to grade II. Raised fatty streaks were 100% grade III (intermediate lesions) and raised lesions were 100% advanced lesions (grade IV, V and VI). This study also shows that with progressive increment of plaque area, the total arterial cross-sectional area increased trying to preserve the lumen area. Endothelial dysfunction was also shown by decrease expression of CD34 immunohistochemical marker in diseased segments.
Conclusions: gross inspection of the vessel is a valuable method for detection of intermediate and advanced lesion, while the differentiation of early lesion from normal vessel needs microscopical examination. Remodeling has a great role in maintaining luminal patency in the major coronary arteries. This study also demonstrates the endothelial dysfunction overlying the atheroma in spite of endothelial integrity.
