    A soil column experiment was conducted to study phosphorus release kinetics from gypsum soils provided by partially acidulated phosphate rock, to compare with conventional phosphate fertilizers and soil ability to release phosphorus over time Under a controlled environment. Two fertilizer sources were evaluated, the first was phosphate rock partially acidulated with sulfuric acid at concentrations of 30%, 40%, 50%, 60%, 70%, the second source was traditional phosphate fertilizers, namely single superphosphate(SSP) and triple superphosphate (TSP). Sulfuric acid concentrations were added and thoroughly mixed with gypsum soil. Plastic column was filled with acidulated soil. A funnel was placed under each column to collect leachate. Irrigation water was applied at a constant depth for a month. From each column, the leachates were collected with interval time of 24 hours, the Soluble phosphorus in the leachate was measured daily over a one month. Among all treatments, the level of partial acidulated 70% superior to all treatments in increasing the phosphorus solubility, where gave the highest reached 7.491 mg L-1after on month. Conversely, the Soluble phosphorus was 3.015, 3.184 mg L-1 after 30 days for traditional phosphate fertilizers, SSP and TSP respectively. When soluble phosphorus data were subjected to kinetic equations, the results showed that the best equation to describe the release of phosphorus was zero-order equation, where it gave the highest coefficient of determination (R2) and the lowest standard error (SEe). Moreover, the highest phosphorus release rate constant was observed in the partial acidulated treatment of 70% compared to the other treatments.

    This study presents a novel method for separating asphaltene from crude oil at room temperature, eliminating the need for heating or refluxing. Traditional methods often suffer from high energy consumption, costly equipment, and safety risks associated with flammable steam. This research focuses on deasphalting heavy crude oil from southern Iraq, containing 3.934 wt.% of asphaltene. Using a lab-made flow injection analysis system, 27 experiments were conducted, varying solvent flow rates (10 mL/min to 50 mL/min), mixing coil lengths (200 cm to 300 cm), and combinations of aromatic and aliphatic solvents. An optimal design (custom) and response surface method (RSM) were employed to pinpoint the best conditions. The optimal deasphalting process involved a solvent flow rate of 50 ml/min, a 300 cm mixing coil, and a xylene/n-heptane (1:10 vol/vol) solvent blend. Statistical analysis confirmed the significance of parameters, encompassing single parameters, interactions, and quadratic effects, all with p-values under the 0.05 confidence level. The efficiency of the deasphalting procedure was assessed practically and theoretically, yielding efficiency percentages of 71.97% and 73.48%, respectively, for asphaltene extraction. This innovative method offers a promising solution for efficient and safe asphaltene separation from crude oil without the need for energy-intensive processes
  • Characterization and screening of metals, metalloids and biomarkers in crude oil by ICP–MS/OES, and GC–MS techniques after digestion by microwave-induced combustion

    A method for digestion of light and medium Iraqi crude oils (Basrah and Khanaken oils) using microwave‐induced combustion (MIC) in closed vessels is described for the determination of Hg, Au, Cu, Al, Ca, Co, K, Mg, Si and Sr by inductively coupled plasma optical emission spectrometry (ICP–OES) and Mo, Ti, Mn, Li, Se−1, Rb, Ag, Ba, Pb, As, Cd, Cr, Fe, Ni, V and Zn by inductively coupled plasma mass spectrometry (ICP–MS). Upon using MIC it was possible to obtain lower limits of detection by ICP–MS and also by ICP–OES compared with those obtained by microwave‐assisted digestion. The MIC was the best choice with regard to the possibility of using dilute nitric acid as an absorbing solution, which is important to minimize the interference encountered by ICP–MS and ICP–OES.The physicochemical parameters and some contaminants of crude oil samples were analyzed to classify and assess the quality of the crude oils. This study determines the viability of the use of Fourier transform infrared spectroscopy as an alternativee to traditional petroleum geochemical methods for crude oil characterization. The infrared fingerprints agree with the results obtained from GC–MS analysis.
