Research progress on the effects of nanoparticles on gas hydrate formation

Abstract

The use of nanoparticles and their effects on thermodynamics and kinetics during the hydrate formation process is summarized. For their application in drilling fluid and cement slurry, it is found nanoparticles must be used in conjunction with surfactants to be effective.

Comprehensive Review and Perspectives of CO2 Hydrate Storage in Subseafloor Saline Sediments: Formation, Stability, and Optimization Strategies

“…Generally, systems with NPs exhibit a shorter induction time compared to pure water systems. 82,83,138 This observation indicates that the presence of NPs effectively reduces the time required for hydrate nucleation, leading to quicker initiation of the process. Numerous studies has revealed that the induction time reduces with rising NP concentrations.…”

Systematic Study of Nanohybrids of ZnO Nanoparticles toward Enhancement of Gas Hydrate Kinetics and the Application in Energy Storage

“…17,18 In the case of gas hydrates, the nanoparticles ranging from 1 to 100 nm in size have been studied for their KHP-like behavior. 32 It was observed that studied nanoparticles effectively enhanced heat transfer and, to some extent, contributed toward mass transfer. 33 Silica nanoparticles were studied with diverse functionalizations imparting gas hydrate inhibition properties and are applicable in maintaining flow assurance.…”

Environmentally Sustainable Large-Scale CO2 Sequestration through Hydrates in Offshore Basins: Ab Initio Comprehensive Analysis of Subsea Parameters and Economic Perspective

“…The gas hydrate as a CO 2 storage technology has experienced apparent acceleration among scientists, scholars and researchers at various levels as evident from the research publications analysis shown in Figure a. However, most of the research papers published in the CO 2 gas hydrate domain were focused on additives/nanoparticles, nucleation, kinetics, and their growth theories/models, and only a few were focused on oceanic sequestration, as shown in the Scopus data analysis (Figure a), especially in porous media that closely aligned with subsea basins. The majority of studies on the CO 2 sequestration in porous media were focused on the CO 2 –CH 4 exchange process not on subsea sedimentary CO 2 sequestration alone. , However, the in-depth analysis of hydrate-forming conditions in actual oceanic and subsea conditions in relation to NBZ and HFZ is not available in the open literature.…”
