Text of Abstract
Hydrates are crystalline structures formed when water molecules trap gas molecules under high pressure and low temperature conditions, creating solid, ice-like compounds. Motivated by potential applications in energy storage, this study explores hydrates formed in a brine water and crude oil emulsion at 4°C and 100 bar. The images illustrate the hydrate after a rheometric test, along with micrographs that reveal the detailed structure of the sample. After the hydrate dissolved, a stunning water crystal was observed, highlighting the intricate processes that occur during phase transitions. These visuals provide a comprehensive understanding of hydrate slurry non-Newtonian behavior, contributing to advancements in energy storage technologies.
