A Comprehensive Review on the Rapid Hydrate Formation for CO₂ Capture: Characteristics, Mechanism, and Applications

Greenhouse Gases Science and Technology, Journal Year: 2025, Volume and Issue: unknown

Published: March 21, 2025

ABSTRACT CO 2 , being a major greenhouse gas, is regarded as an important contributor to global warming and environmental problems. capture separation are efficient approach for reducing emissions in the atmosphere. A hydrate method of provides feasible solution emission reduction However, rapid formation crucial using technique. As consequence, this paper comprehensively reviewed characteristics kinetic law hydrate, well deeply analyzed influences temperature pressure conditions, gas–liquid ratios, additives, hydration reaction system, process, other factors on its process. On basis, quantitative impact regulatory mechanisms different nucleation growth process were analyzed. The influence laws temperature, pressure, ratio selection, additive concentration, type system detailed. enhancement under multiple elucidated. application by challenges summarized. In end, key problems future directions pointed out. synergistic mechanism through still need be further investigated. Developing new reactor structures optimizing promoting hydrate.

Study on Growth and Deposition and Mechanical Properties of Hydrate in the Presence of Silty Sand

ACS Omega, Journal Year: 2025, Volume and Issue: 10(12), P. 12334 - 12345

Published: March 19, 2025

The safe exploitation and transportation of hydrates are seriously threatened by hydrate growth deposition in the flow channel. However, silt impurities inevitably present channels. This article aims to clarify how slit affect growth, deposition, mechanical properties. process presence silty sand on pipe walls different solution systems wall materials was investigated. results indicated that, deionized water system for both metallic nonmetallic wall, sodium dodecyl sulfate (SDS) rate increased 131.48, 114.76, 84.89%, respectively, after adding a 9.0% volume fraction sand. Additionally, adhesion strength between at contents measured. It found that ranged from 140.61 234.64 kPa. With an increase content, first then decreased, reaching maximum when 3%. extension formation time, up 57.62%. Furthermore, mechanism proposed. SDS differed system. In SDS, no dendritic observed around generated hydrate, while were with materials, more forming wall. After addition sand, initial position shifted interior droplet inside droplet. work provided data support preventing plugging channel great significance ensuring production hydrates.
