Eggshell‐Based Biochar for Superior Adsorption of Crystal Violet Dye and Fluoride From Wastewater

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Present study investigates the efficiency of eggshell biochar as a low‐cost and ecofriendly adsorbent for the simultaneous removal of fluoride ions and crystal violet (CV) dye from wastewater. The eggshell waste was pyrolyzed to produce biochar, which was thoroughly characterized and subsequently employed for contaminant adsorption.

Stability and Behavior of Bulk Nanobubbles Under Reservoir Conditions

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Compared with microbubbles, nanobubbles exhibit superior stability, higher specific surface area, and smaller size. These characteristics have increasingly attracted the attention of petroleum researchers. However, existing literature lacks studies on nanobubble concentration and size under harsh reservoir conditions. To address this gap, this

Mechanism of Hydrogen Sulfide Generation and Prevention Strategies in Oil and Gas Fields: A Case Study of the Sickle Bay Operation Area

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT To address the persistent exceedance of hydrogen sulfide (H2S) concentrations and the limited effectiveness of existing treatments in the Sickle Bay oil production area, this study deeply analyzes the mechanism of H2S generation in the Sickle Bay oil production area and proposes targeted prevention and control strategies. The results show that

Characterization and Modeling of Industrial Phosphoric Acids' Rheological Behavior: Impact of Magnesium Monoxide on Viscosity

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study investigates the rheological behavior of industrial phosphoric acids (H3PO4) produced at the JORF–LASFAR phosphoric plant in Morocco, with P2O5 concentrations of 18%, 29%, 42%, and 54%. Rheological measurements were performed using a rotary cylinder rheometer over a shear rate range of 1–1000 s−1.
