In this work, the effect of current density, deposition period, electrolyte temperature, distance between electrodes, ratio of anode to cathode surface area and cathode rotation on the current efficiency and powder properties such as apparent density, grain size, grain size distribution and grain morphology on powder properties and current efficiency are studied. A deposition system composed of Perspex cell, two copper electrodes ( 96.8% purity), electrolyte composed of 90g/l CuSO4 and 120g/l H2SO4 as well as the electrical connections. Betts method was followed by this study.The automatic sieve shaker was used to determine the grain size, while the atomic spectroscopy was used to determine copper purity. Moreover, both optical microscope and SEM were used to estimate powder morphology. It is found that current efficiency is increased with increasing deposition time and electrolyte temperature. It is also found to be decreased with increasing current density, distance between the electrodes, ratio of anode to cathode surface area and rotation of cathode electrode. The results showed also that particle size is increased with increasing the distance between the electrodes and increased with increasing the ratio of anode to cathode surface area and cathode rotation. Further more, the obtained data indicated that the maximum and minimum achieved fine grain percent (

Chemical precipitation is done by controlling the (PH) of wastewater by adding a suitable hydroxide ,different hydroxides were used like the hydroxides of sodium ,calcium and potassium 0.05N each and sodium carbons 0.1N in removing heavy metals of wastewater. The study has taken prepared samples contain different concentrations of heavy metals ions like cupper 2,4 and 6 ppm zinc 5,10 and 15ppm and manganese 2,5,8 ppm Jar taste is used to show the chemical precipitation. Fast and slow mixing periods were written down to get the velocity gradient (G) and (GT) The used materials were highly efficient to remove the ions of metals. The removed amount of metals was measured by (AAS) Atomic Absorption spectroscopy.

Abstract: ان التاكل الداخلي في انابيب الصلب الكربوني الذي يحدث بوجود غاز ثاني اوكسيد الكربون يعتبر مشكلة جوهرية في صناعات النفط والغاز وهو يقترن دائما مع وجود الماء. ان احتمالية حدوث التاكل تزداد بصورة عامة مع تزايد نسبة الماء ومع زيادة مستوى الماء المنتج تزداد مع | Internal corrosion of carbon steel pipelines occurring in the presence of CO2 is a substantial problem in the oil and gas industries. It is always associated with the presence of free water. The likelihood of corrosion generally increases with the volume fraction of the water phase. As the produced water level increases, the corrosion rates of carbon steel increase very rapidly and causes damage of petroleum and gas pipelines. The present research work focuses on the investigating of the corrosion rate of carbon steel as flow line in crude oil production with CO2 content employing three Iraqi crude oil (Kirkuk crude oil, Halfaya crude oil, Rumalia crude oil) with different brine concentrations [1%NaCl, 2%NaCl, 3%NaCl]. Determining the corrosivity of Iraqi crude oil was studied for the first time. Experiments were performed in an autoclave test apparatus, crude oil - produced water mixtures, water cuts were (0, 10, 20, 30, 40, and 100%), and total volume of mixtures inside the autoclave was always kept at 100ml and temperature (20, 40, 60°C). For all experiments, CO2 partial pressure was maintained at (4 bar) and rotational speed (500 rpm).The corrosion rates were determined by the weight loss technique. The results revealed that the corrosion rates of carbon steel increased by increasing water cut and temperature, but decreases with increasing salt concentration for all types of crude oil. Results also indicated that different crude oil has significantly different effects on corrosion of carbon steel, with identical brine compositions. Therefore, Rumaila crude oil exhibits the highest corrosion rates and Kirkuk crude oil exhibits the lowest corrosion rates while Halfaya crude oil exhibits a moderate corrosion rates e.g. at 1% NaCl, 20% water cut, temperature 60°C, pressure 4bar, the corrosion rate of carbon steel in Rumaila crude oil is 0.9163mm/yr whereas it is 0.564 mm/yr and 0.705 mm/yr in Kirkuk crude oil and Halfaya crude oil respectively. The Corrosion Rate Break produced water level was determined from the experiments. These tests are employed to evaluate the requirements for corrosion inhibitor treatment. At 100% water cut (brine/CO2) the corrosion rates of carbon steel was the highest. The presence of crude oil decreases the corrosion rates e.g. at 1% NaCl,100% water cut(brine/CO2) the corrosion rate is 7.1197 mm/yr, whereas at 40% water cut/ Rumaila crude oil the corrosion rate is 1.4097 mm/yr.

Moreover using the present models to represents the experimental data.A Laboratory scale apparatus is designed and constructed taking into account the most important parameters effecting adsorption. In performing the present study Actual wastewater of Baiji refinery is taken to perform the experimental work.The results indicated that phenol, parachlorophenol and Benzene can be removed completely using granular activated carbon. Also the results indicated that breakthrough and exhaustion time are inversely proportional with the concentration of pollutants and liquid hourly space velocity, while they are directly proportional with the thickness of granular activated carbon. Its found that the Adsorption capacity is directly proportional with the concentration of pollutants and liquid hourly space velocity. The results of this work indicated also the thickness of adsorption zone, which is calculated depending on the result of this study, is directly proportional with liquid hourly space velocity.Application of the most famous available models that are used to represent adsorption phenomena on our experimental data show that only Freundlich model gives excellent agreement.In order to find mathematical model for breakthrough and exhaustion time as a function the most important parameters, an advanced computer program is used.We found two mathematical model for breakthrough and exhaustion time as a function of granular activated carbon thickness, liquid hourly space velocity and the concentration of pollutants. These two models give acceptable agreement with the experimental results.The adsorption capacity for the three pollutants are calculated and found to be directly proportional with liquid hourly space velocity and pollutants concentration.
