Abstract This comprehensive study explored the removal of methylene blue (MB) from aqueous solutions as a model pollutant, utilizing solar-driven photocatalysis with nano-sized titanium dioxide (TiO 2 ) and composites activated carbon (AC) reduced graphene oxide (RGO). research introduces continuous solar reactor instead conventional batch experiments investigating its design configuration. Utilizing response surface methodology (RSM), determined optimal process conditions (MB concentration at 30 mg/L, pH 8.82, irradiation time 138 min), under which TiO achieved 93.13% MB efficiency. The further revealed that integration AC RGO (5% wt.) significantly enhanced photocatalytic degradation. /AC composite 98.3% degradation in min exposure, related to large specific area 146 m /g pore volume 0.439 cm 3 /g. Likewise, /RGO demonstrated 97% 102 0.476 /g, better than nano-TiO . Additionally, investigated role configuration on removal. Using 26 mm Pyrex tube diameter 15 long parabolic aluminum concentrator inclined 30° optimally peak Recyclability tests shown noticeable decrease efficiency 56.03% without regeneration; however, after regeneration following third cycle, recovered 70.07%. Thereby, this paper an innovative, continuous, well-designed system for dye removal, employing improved statistically optimized conditions.

The global concern over heavy metal pollution necessitates urgent measures to safeguard human health and the environment. This study focuses on employing triethylenetetramine (TETA)-functionalized MIP-206-OH (TMIP-206) as an effective adsorbent for removing Pb(II) from wastewater. TMIP-206 was synthesized via a hydrothermal method followed by functionalization with TETA. Kinetic studies demonstrate that lead removal conforms pseudo-second-order model, indicating efficient process. Experimental results reveal aligns Langmuir isotherm, exhibiting maximum capacity of 267.15 mg/g ions. sorption efficiency Pb ions remains stable across six cycles, reduction less than 15%. Optimal adsorption performance is observed at pH 6. These findings underscore potential alternative adsorbing aqueous environments, addressing challenge pollution. Future research should explore scalability long-term stability TMIP-206-based adsorbents enhance their practical applicability in diverse environmental contexts contribute broader strategies mitigating contamination.

A well can be produced and exploited when it has production power, in other words, if the does not have enough pressure, will able to flow. Artificial is a method increase lifespan of production. The studied this article significant annual lower pressure drop; So now with current existing well, possible send oil separator first stage exploitation unit. Among solutions maintain or flow use artificial extraction. In article, an attempt been made simulate effect using core pipe, gas pumping installing electric submersible pump (ESP) on rate by data static test. PIPESIM software was checked, then best extraction for well. Finally, installation ESP determined selected as

Preparation and Mechanism of EP-HMTA-SiO2 Nanocomposite Polymer Gel for Enhancing Oil Recovery

Processes, Год журнала: 2025, Номер 13(3), С. 596 - 596

During oilfield production, organic substances such as asphaltenes and resins present in crude oil are prone to adsorb onto the surfaces of reservoir rocks. This adsorption process can lead conversion hydrophilic rock into more oleophilic interfaces, which turn reduces permeability porosity reservoir, ultimately affecting overall recovery efficiency. Consequently, targeted modification wettability presents a promising strategy for enhancing rates. In this study, polymer layer comprising large molecular side chains hydroxyl groups was synthesized on surface nano-SiO2 enhance thermal stability polymer. Additionally, were employed improve core material reduce interfacial tension. The polymers characterized using techniques FTIR TG, results revealed that modified SiO2 exhibited superior performance reducing both tension contact angle when compared SiO2. Injection 0.4 wt% EP-HMTA-SiO2 solution resulted an increase rates by 16.4% 13.2% medium- low-permeability cores, respectively.
