Published: May 2023

In the present work, a closed loop circulation system consist of three testing sections was designed and constructed. The testing sections made from (3m) of commercial carbon steel pipe of diameters(5.08, 2.54 and 1.91 cm) . Anionic surfactant  (SDBS )with  concentrations  of (50,  100,  150, 200 and 250 ppm)  was tested as a drag reducing  agent.  The additive(SDBS)studied using crude oil from south of Iraq. The flow rates of crude oil were used in 5.08 and 2.54 cm I.D. pipes are (1 - 12) m3/hr while (1-6) m3/hr were used in 1.91 cm J .D. pipe . Percentage drag reduction (%Dr) was found to increase by increasing solution velocity, pipe diameter and additives concentration (i.e. increasing Renolds number). Also it was found that there is no change in apparent physical properties (viscosity) of crude oil after the addition of SDBS. The higher value of drag reduction of 54% in 5.08 cm I.D. was observed using 250 ppm SDBS surfactant dissolved in the used crude oil at flow  rate of 12 m3/hr. Friction factor  was calculated from  experimental data. The friction factors values for pure solvent lies near or at Blasius asymptote suggested for flow of Newtonian fluids. After the addition of small amount of SDBS, the friction factor values were positioned below Blasius asymptote toward Virk maximum drag reduction asymptote, which was never reached.

The corrosion  behavior  of mild sleet  in saturated  aerated  and de-aerated  Ca(OH)2 solution  was  investigated  using electrochemical measurements. The work was carried out with small coupons immersed in solutions containing different quantities of NaCl in presence of various NaN02 concentrations as corrosion inhibitors. It has been found thal:(1 ) In presence  of NaCl,  the time required  to reach O2  evolution potential  in de-aerated  Ca(OH)2 polarized  at  10μA/cm 2 is function of inhibitor concentration and it becomes lass as NaN02 increases compared with zero presence indicating the effectiveness of NaN02 as anodic corrosion  inhibitor. (2) In absence of NaCl, the Lime required to reach O2 evolution potential in de-aerated solutions is less that in aerated solutions when inhibitor increases from 0 to 0.3 wt. %. (3) In presence  of sufficient  chloride in de-aerated Ca(OH)i solution, the passive film  may broken down locally.

The minimization, treatment and disposal of drilling wastes especially oily wastes are important environmental issues.

In this research two fungal isolates named Pleurotus ostreatus and Trichoderma harzianum were chosen carefully f or the purpose of biotreatment of oily drilled cuttings which resulting from  drilling oil wells using oil based muds (OBMs).

A relationship of total petroleum hydrocarbon degradation in oily drilled cuttings with time has been obtained. The results showed that Pleurotus ostreatus and Trichoderma harzianum can be considered hydrocarbon degrading microorganisms and the used biotreatment is cost effective process since most of the materials used in the cultivation and growth of the present fungi  were available and cheap agricultural wastes.

The best hydrocarbon degradation was observed in case of using both fungi together with 5 % by weight microorganisms concentration ratio (MCR) and with the same ratio of nufrients expressed as CIN/P equal to 100150110 nutrients components ratio which gave average total petroleum  hydrocarbon degradation of about 205 ppm per  day.

Published: May 2023

In this study  the isomerization of desulfuerized light Iraqi petroleum naphtha (Al-Dura Refinery) with boiling point range of 37 to 124 °C , 80.5 API specific gravity and 68.2 octane number has been investigated. Two types of catalysts were prepared (Pt/HX and Pt/SrX) by impregnation of 0.8 wt% Pt on l 3X-zeolite. The catalyst activity and selectivity toward isomerization, and catalyst deactivation were investigated.

The isomerization unit consisted of a vertical tubular stainless steel reactor of 2 cm internal diameter, 3 cm external diameter and 68 cm height. The operating pressure was atmospheric for all experimental runs.  The liquid flow of light­naphtha was 0.4 Uh, and the catalyst weight was 50 gm, H/ H.C ratio used was 4 for all experimental runs. The isomerization process was studied at different temperatures of 250, 270, 275, 300, 325, and 350 °C . It was found that, the optimum isomerization temperature is 270 °C.

The isomerization activities and selectivities as a function of time showed high activity at the beginning of the reaction and were deactivated rapidly. This indicates that the deactivation of Pt/HX and Pt/SrX results from the blocking of pore mouth by the deposited carbon. The following deactivation decreasing order, Pt/HX > Pt/SrX was found. On the other hand, Pt/HX catalyst shows higher activity and selectivity than that of Pt/SrX

It was concluded that, only an average o/ 90 wt% of the carbon atoms feed  into the reactor (light naphtha) is detected " the product stream due to formation of coke deposits which leads to catalyst deactivation. The results clearly showed 1at hydrogen is necessary for the hydrogenation of olefins in order to prevent oligomerization reaction that leads to coke formation and catalyst deactivation.

Authors: Al-Hemiri Adel , Akkar Suhayla
Published: May 2023

In the literature, several correlations have been proposed for hold-up prediction in rotating disk contactor. However,these correlations fail to predict hold-up over wide range of conditions. Based on a databank of around 611measurements collected from the open literature, a correlation for hold up was derived using Artificial Neiral Network(ANN) modeling. The dispersed phase hold up was found to be a function of six parameters: N, vc , vd , Dr , c d m / m ,s . Statistical analysis showed that the proposed correlation has an Average Absolute Relative Error (AARE) of 6.52%and Standard Deviation (SD) 9.21%. A comparison with selected correlations in the literature showed that thedeveloped ANN correlation noticeably improved prediction of dispersed phase hold up. The developed correlation alsoshows better prediction over a wide range of operation parameters in RDC columns.

Authors:   Volgograd branch of A. N. Kostyakov All-Russian Research Institute for Hydraulic Engineering and Land Reclamation, Volgograd, Russian Federation, Lytov Mikhail N.
Published: May 2023

Purpose: to develop the concept of irrigation management systems using integrated artificial intelligence technologies. Materials and methods. The working hypothesis of the research was the assumption of the priority of the cluster application of artificial intelligence technologies in solving urgent problems of irrigation management. At the same time, the basis of the information-computing unit of the irrigation control system should be deterministic algorithms using proven solutions. Results. Within the framework of the proposed concept, a neural network can be used as the basis for solving a problem, or it can only be used to adapt the parameters of the models used. The impact points of traditional, deterministic - analytical irrigation management systems and artificial intelligence technologies are determined by the need to adapt parameters, fine-tune the coefficients of the methodological tools used. At the same time, the scope of application of artificial intelligence in solving problems of irrigation management is quite wide. Artificial intelligence technologies can be used to solve the problems of irrigation planning and operational management, image recognition in satellite monitoring of soil moisture, interpolation of soil moisture data by area, forecasting the soil moisture profile. An algorithm using artificial intelligence technologies to improve the reliability of forecasting the total water consumption of irrigated crops in the regional and landscape aspect is developed by research. The proposed algorithm allows the system to self-learn and refine the regional values of bioclimatic coefficients, with respect to cumulative influence of local factors. Conclusions: a concept has been developed and new scientific approaches have been proposed to effectively solve the problem of adapting the parameters of methodological irrigation management tools at the level of an irrigated field, and even taking into account intra-field variability.

Purpose: Carrying out a comprehensive monitoring to assess the technical condition of the reinforced concrete elements of the Nevinnomyssky Canal end outlet, based on the assessment of reliability parameters using non-destructive control methods. Materials and methods. An instrumental examination of the reinforced concrete elements of the end outlet of the Nevinnomyssky Canal, including the inlet and outlet channels, was carried out by the method of assessing the technical condition using non-destructive method devices in order to assess the technical condition and residual resource of hydraulic structures, namely: defor-mation and structures displacement in regards to design position, cracking, destruction of sur-face zones, corrosion and cavitation damage, etc., compliance with the project of the actual conditions of structure operation, the state of landslide areas and areas of coastal reformation, the state of hydromechanical equipment, corrosion of metal parts of equipment, the detection of precipitation, displacement, deformation, stress, roll of elements. Results. A survey of the technical condition of slopes and reinforced concrete elements was carried out. The adjunc-tions of earthworks to concrete structures, the state of temperature-sedimentary seams of con-crete and reinforced concrete structures that could affect the stability of structures were exam-ined. Conclusions. The current state of the end outlet of the Nevinnomyssky Canal indicates the soil slopes reformation during the period of the hydraulic structure operation. It was de-termined that the reinforced concrete structures of the outlet are, in general, in a satisfactory condition and meet their functional purpose. The structures of the first and second compart-ments have already undergone large-scale destruction and have lost part of their bearing ca-pacity and even part of the material, since the first and second compartments are in urgent need of repair. It is necessary to restore the waterproofing of the bottom and sides of the tray at the joints of the compartments and cracks in the bottom by injecting a waterproof sealant into the seams and cracks.

Purpose: carrying out filtration calculations of the main canals (MC) and comparison (comparative analysis) of the obtained values. Materials and methods. The object of study is the water supply network of the Sarpinsky irrigation and watering system (SOOS) in the North of Kalmykia. The initial data for the study were the field survey data of the system canals, as well as materials for official use obtained in the operating organization. When performing filtration calculations, the physical and geographical features of the irrigation network location area were taken into account and the method for calculating backed fil-tration from a canal (in an earth channel) was used under conditions of a steady movement of the seepage discharge. The calculation was based on the application of the filtration resistance method. Results and discussion. Taking into account the features of the geological and soil conditions of the northern regions of Kalmykia, the calculated values of filtration losses from the MC system were determined, which amounted to 2.7–6.51 l/(day sq. m) for the calculated sections of the MC VR-1 and 5.46 l/(day sq. m) – for MС R-1. Comparison of the data ob-tained for the MC SOOS with the results of studies of unlined sections of the Great Stavropol Canal, laid in the similar geological conditions, confirmed the authors' assumption that the values of seepage flow rates from the MC were significantly affected by the presence of clay soils at the canal bottom. Conclusions. As a result of the research, it was found that the value of filtration losses from MC SOOS is significantly affected by the geological and soil features of the system location area, and in particular the low permeability of mantle loams, as well as the presence of impervious Khvalyn clays of marine origin. The studies of other authors have confirmed that the close occurrence of these clays to the day surface contributes to flooding and land salinization, this was not taken into account when developing irrigation in the north of the region.

Purpose: to study the total stresses in the rectangular section conduit body TOTAL S-YY and S-XX while analyzing the influence of the soil height above the conduit and the load from the vehicle axle on the conduit. At the same time, the influence factors varied in the range: the soil height above the conduit from 0.5 to 1.2 m, the load from the axle of the car on the conduit from 5 to 40 t. Materials and methods. The study of a complex system was carried out in two stages. At the first stage, using a numerical method based on the Midas GTX NX program, which is able to take into account the complex joint work of the conduit structure located in the ground, the stresses in it were calculated. Further, the resulting array of numbers, reflecting the physics of the processes occurring when the response function is influenced, for which the total stresses of the perturbation factors are taken and the height of the soil above the conduit and the load on the conduit from the car, was subjected to digital analysis. Results. The total stresses in the conduit at a constant soil height above it are charac-terized by a very active linear relationship with the force on the soil for both horizontal and vertical stresses. Horizontal stresses S-XX in the range of argument change from 5 to 40 t provide a change in the response function by 28.82 %. At the same time, the vertical S-YY stresses in the conduit at a constant height of the soil above it are almost as linearly active and provide a change in the response function by 24.79 %. Conclusions: with an increase in the load from the car on the ground above the conduit, the stresses in the latter have minimal val-ues, which occur at a greater embankment height of the.
