Summary: This study proposes a new transient model for gas hydrate slurry flow, which combines a two-fluid model and temperature equation for describing the two-phase flow and establishes equations for the particulate phase flow using Eulerian and Lagrangian approaches. The model is verified and applied to analyze the transient behavior of gas hydrate slurry multiphase flow, as well as conducting sensitivity analysis on flowrate, initial droplet size, and drag force. These results provide practical insight into hydrate slurry multiphase flow and contribute to better hydrate management in the petroleum industry.

Summary: The formation of gas hydrates is a significant issue in oil and gas pipelines, as they cause blockage and disrupt normal flow. Injecting ionic liquids as hydrate inhibitors is a solution, and imidazolium-based ionic liquids have been found effective. These inhibitors act as thermodynamic inhibitors, hydrate inhibitors, and anti-agglomerates.

Summary: The research found that in oil-free gas-water systems, traditional anti-agglomerants had no effect on agglomeration, while kinetic inhibitors could slow down hydrate formation but not inhibit agglomeration. An amphiphilic amide compound DCA effectively prevented hydrate agglomeration and blockage by reducing the cohesion force between hydrate particles and changing the surface characteristics of the particles, preventing liquid bridges from forming and inhibiting adhesion and agglomeration.

Summary: This paper presents a detailed analysis of the gas-phase distribution law and the vortex distribution in the flow passages within the oil-gas multiphase pump by means of numerical calculations, supplemented by experimental verification. The results show that the gas phase is mainly concentrated in the diffuser at different GVFs, and the gas phase gathering in the diffuser becomes more significant with the increase in the GVF.

Summary: Based on a high-pressure visual micro-force measurement system, this study measured the forces between hydrate particles and pipe walls. The effects of anti-agglomerants on adhesion force were evaluated, showing significant reductions. The addition of anti-agglomerants weakened the tensile strength of the hydrate shell, leading to decreased adhesion force.

Summary: The hydrodynamics of bubble columns in the heterogeneous regime is studied experimentally. The void fraction field at small scales is analyzed and found to differ significantly from a random Poisson process in the heterogeneous regime. Meso-scale structures, such as clusters, void regions, and intermediate regions, are identified and found to drive the motion of bubbles. The relative velocity of bubbles is related to the concentration and characteristic size of these meso-scale structures, and a cartoon of the internal flow structure is proposed based on their values at large gas superficial velocities.

Summary: The study on hydrate agglomeration shows that the correct dosage of anti-agglomerants (AAs) can prevent hydrates from agglomerating and causing blockages in pipelines, allowing them to flow as noninteracting slurries in deep-sea oil wells. The performance of AAs varies between model oil and crude oil systems, and multiple parameters need to be considered when evaluating the effectiveness of AAs.

Summary: Some crude oils contain natural surfactants that prevent hydrate agglomeration, which is linked to the aggregation state of asphaltenes. Artificially modifying the aggregation state of asphaltenes can alter the natural hydrate antiagglomeration properties of crude oils. This finding could have implications for novel hydrate management strategies that utilize the intrinsic antiagglomerant properties of certain crude oils.

Summary: In this study, a hybrid structure, MIL-53(Al)@MWCNT, was synthesized by combining MIL-53(Al) particles and -COOH functionalized multi-walled carbon nanotube (MWCNT). The hybrid structure was then embedded in a polyethersulfone (PES) polymer matrix to prepare a mixed matrix membrane (MMM) for CO2/CH4 and CO2/N2 separation. The addition of MWCNTs prevented MIL-53(Al) aggregation, improved membrane mechanical properties, and enhanced gas separation efficiency.

Summary: Non-conventional amines are being researched worldwide to overcome the limitations of traditional amines like MEA and MDEA. Adequate process and thermodynamic models are crucial for understanding the applicability and performance of these amines in CO2 absorption, but studies on process modeling for these amines are limited. This study used rate-based modeling and Deshmukh-Mather method to model CO2 absorption by DETA solution in a packed column, validated the model with experimental data, and conducted a sensitivity analysis of mass transfer correlations. The study also compared the CO2 absorption efficiency of DETA solution with an ionic solvent [bmim]-[PF6] and highlighted the importance of finding optimum operational parameters for maximum absorption efficiency.

Summary: The utilization of smart water in EOR operations has gained attention, but more research is needed to understand the complex mechanisms involved. This study investigated the interfacial tension between smart water and crude oil, considering factors such as salt, pH, asphaltene type, and aged smart water. The results revealed that the hydration of ions in smart water plays a key role in its efficacy, with acidic and basic asphaltene acting as intrinsic surfactants. The pH also influenced the interfacial tension, and the aged smart water's interaction with crude oil depended on asphaltene type, salt, and salinity.

Summary: In this study, cobalt-based metal-organic frameworks (Co-based MOFs) were used as supports and co-catalysts to confine the NHPI catalyst, solving the leaching issue. The NHPI@Co-MOF with carboxyl groups exhibited stronger acidity and facilitated the generation of active oxygen radicals O2•, resulting in enhanced catalytic activity. This research provides valuable insights into the selection of suitable organic linkers and broadens the research horizon of MOF hybrids in efficient oxidative desulfurization (ODS) applications.

Summary: In this study, high-performance solid catalysts based on phosphotungstic acid (HPW) supported on Zr-SBA-15 were synthesized and evaluated for the one-pot conversion of furfural (FUR) to γ-valerolactone (GVL). The catalysts were characterized using various techniques, and the ratio of HPW and Zr was found to significantly affect the selectivity of GVL. The HPW/Zr-SBA-15 (2-4-15) catalyst exhibited the highest GVL yield (83%) under optimized reaction conditions, and it was determined that a balance between Bronsted acid sites (BAS) and Lewis acid sites (LAS) was crucial for achieving higher catalytic performance. The reaction parameters and catalyst stability were also investigated.

Summary: Integrating CO2 capture with biomass-fired combined heat and power (bio-CHP) plants is a promising method for achieving negative emissions. This study develops a reliable data-driven model based on the Transformer architecture to predict the flowrate and CO2 concentration of flue gas in real time. The model validation shows high prediction accuracy, and the potential impact of meteorological parameters on model accuracy is assessed. The results demonstrate that the Transformer model outperforms other models and using near-infrared spectral data as input features improves the prediction accuracy.
