Micro/Nanoparticle Characteristics and Flow in Porous Media: A Review towards Enhanced Oil Recovery

Energies, Год журнала: 2024, Номер 17(16), С. 4136 - 4136

Опубликована: Авг. 20, 2024

Micro/nanoparticles have emerged as pivotal agents in enhancing oil recovery (EOR), offering novel approaches to optimize the extraction processes complex reservoirs. This review comprehensively examines utilization of these particles, focusing on their unique material and structural characteristics that facilitate significant modifications flow dynamics within porous media. These particles effectively reduce interfacial tension, modify wettability, improve sweep efficiency, thereby efficacy. Through a synthesis current research spanning field-scale experiments, core flood studies, micro-model investigations, this paper highlights integration micro/nanoparticles practical EOR applications. Despite proven potential, challenges such scalability, environmental concerns, economic feasibility persist, requiring ongoing advancements particle engineering simulation technologies. aims provide thorough understanding landscape future prospects EOR, underlining need for innovation interdisciplinary collaboration overcome existing hurdles fully exploit technologies gas industry.

Upcycling Scented Pandan Leaf Waste into High-Value Cellulose Nanocrystals via Ultrasound-Assisted Extraction for Edible Film Reinforcement

Foods, Год журнала: 2025, Номер 14(9), С. 1528 - 1528

Опубликована: Апрель 27, 2025

This study aims to optimize the parameters for ultrasound-assisted extraction of cellulose nanocrystals (CNCs) from scented pandan leaf waste and enhance properties edible films reinforced with CNC. The CNC conditions were optimized using response surface methodology (central composite design) by varying two independent variables, including amplitude (25.86% 54.14%) ultrasonication time (11.89 min 33.11 min). optimal 50% 30 ultrasonication, providing CNCs highest yield (29.85%), smallest crystallite size (5.85 nm), crystallinity index (59.32%). extracted showed favorable physicochemical properties, a zeta potential -33.95 mV, an average particle diameter 91.81 nm, polydispersity 0.26. Moreover, sweet potato starch (SPS)-based incorporating various concentrations (0, 2, 4, 6, 8%) fabricated. Increasing improved key film thickness, moisture content, water vapor permeability, tensile strength, light transmittance, color. Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM) analyses confirmed hydrogen bonding, crystallinity, uniform distribution within as content increased. These findings highlight efficient method producing high-quality waste, offering sustainable nanofillers biodegradable films.
