ABSTRACT Ensuring flow in an oil field is one of the most costly problems in oil production and transportation. The fight against the formation of paraffin deposits consists both in the application of methods for the prevention and removal of deposits, and in the modeling of this process. An important parameter for the application of some technologies for preventing the formation of deposits and modeling the temperature regime of the pipeline is the coefficient of thermal conductivity of these deposits. The paper presents a study of the influence of the thermal conductivity of organic deposits on the rate of their formation, measured for 5 hours at the Cold Rod installation. According to the research results, it was found that over time, the thermal conductivity of organic deposits increases, while the rate of deposit formation decreases significantly. This process is explained by an increase in temperature on the surface of deposits due to their compaction and displacement from the volume of the liquid phase. The results obtained are extremely important in modeling the process of deposit formation and modeling a number of technologies to combat them.

ABSTRACT Research was carried out to investigate the use of tributylphosphate (TBP) and enhanced β-diketones for extracting copper from covellite ore leach liquor. The effect of some parameters such as contact time, temperature, phase ratio, equilibrium pH, and extractant concentration on the extent of copper extraction was examined. For the following conditions: temperature 27 ± 2°C, phase ratio 1:1, extraction efficiency of 95.30% total copper was achieved using a mixture of 0.25 mol/L enhanced β-diketones + 0.10 mol/L TBP in kerosene within 15 minutes at pH of 7.8. Furthermore, the stripping of approximately 97.3% of pure copper from the loaded organic phase was successfully attained at optimal conditions. The hydrometallurgical flow chart summarizing the analytical operations for the extraction and recovery process was provided.

ABSTRACT This study aimed to isolate and characterize indigenous bacteria from cadmium-contaminated soil around a coal-fired power plant in Korea for their potential use in biosorption. The 16S ribosomal RNA analysis identified Enterobacter ludwigii G17–1 in the soil, exhibiting a remarkably high minimum inhibitory concentration (2,500 mg/L) for cadmium. The efficiency of cadmium biosorption was investigated under different pH levels (6–9), temperatures (15–40°C), and initial cadmium concentrations (25–100 mg/L), using both live and dead G17–1. The live G17–1 strain exhibited a maximum biosorption efficiency of 50% for 25 mg/L cadmium at 24 hours, while the highest efficiency achieved with dead G17–1 was 48% at 1 hour. The biosorption capacity decreased as the initial cadmium concentration increased. These findings suggest that the isolated bacterium, E. ludwigii G17–1, holds potential for the bioremediation of cadmium-contaminated water and wastewater.

ABSTRACT This paper examines the potential use of pegmatite and marble as additives in amalgamation with Meiganga kaolin to produce stoneware products capable to resist high temperatures as well as enhancement the mechanical characteristics. Two series of ceramic products were formulated by partly replacing kaolin with 0, 3, 5 and 7 wt% of both pegmatite and marble wastes. The specimens were sintered at 1000°C, 1050°C and 1100°C. Fired ceramic samples were characterized by X-ray diffraction, Fourier transform infrared spectroscopy and the microstructure of the products was determined using an environmental scanning electron microscope and energy-dispersive X-ray spectroscopy. Also, the physico-mechanical properties were evaluated. Results divulged that, the addition of pegmatite or marble to kaolin enhances the strength of the ceramic body and act as a fluxing agent by promoting vitrification and glassy phase in clay after firing. The highest flexural strength results were observed with 7 wt% of pegmatite added at 1100 °C, with an increase ~ 35% compared to the control sample. High silica and alumina contents in pegmatite fill in voids, providing densification matrices. The incorporation of pegmatite allows to obtain a ceramic with better mechanical properties and energy saving as compared by the conventional ceramic.

ABSTRACT Currently, drilling operators focus on chemical osmosis as a mechanism to extract water out of shale in order to reduce its pore pressure and increase its strength, however, in doing so, the flux of hydrated ions into shale by means of diffusion osmosis and ionic diffusion is increased. Such practice may lead to an increase in shale’s pore pressure and strength reduction which will definitely negate the beneficial impact of chemical osmosis in combatting wellbore stability problems. For the first time, this work investigated the separate impact of diffusion osmosis on shale’s swelling and subsequent wellbore stability issues. The experimental set-up enabled us to isolate chemical osmosis forces which made diffusion osmosis the only force governing water exchange. Making the water activity of shale equals to that of the aqueous solution disabled chemical osmosis forces and activated ionic diffusion and diffusion osmosis owing to the imposed ionic concentration during the interaction. It was found that diffusion osmosis accompanies ionic diffusion since ions travel with their respective water clouds, also known as associated water. The transport of associated water has caused shale’s swelling in the absence of a water activity gradient (chemical osmosis). This was confirmed through gravimetric water and ion measurements conducted at the end of the linear swelling tests. Results showed that the amount of water exchanged by diffusion osmosis was immense, thus one should not ignore it when designing water-based muds for drilling highly sensitive clays. Results also showed that the amount of water exchanged correlated well with the hydrated diameter of the invading ion. Moreover, results confirmed that the swelling magnitude may be related to the mineralogical composition and cation exchange capacity of shale.
