Description

Technical field [0001] The invention relates to the field of experimental technology, in particular to a visualized gas hydrate dynamics experimental device. Background technique [0002] Gas hydrate is an ice-like clathrate crystal compound formed by gas molecules (such as methane, carbon dioxide, nitrogen, hydrogen sulfide, etc.) and water molecules under low temperature and high pressure conditions. In recent years, with the deepening of gas hydrate research, it has been discovered that the use of gas hydrate for gas separation, storage and transportation can become a new and efficient industrial technology. In simulation studies, the study of the nucleation mechanism and properties of gas hydrates, gas storage capacity and other dynamic properties is the key basis and prerequisite for the hydrate method gas separation and storage and transportation technology, which has direct guiding significance for practical applications . [0003] The formation process of gas hydrate is a...
