Description

technical field [0001] The invention relates to a simulation experiment device, in particular to a kinetic simulation experiment device for hydrate formation. Background technique [0002] Natural gas hydrate is a solid compound formed by low molecular weight hydrocarbon compounds and water in natural gas at low temperature and high pressure. It is the most typical gas hydrate existing in nature. Natural gas hydrate has large reserves, wide distribution, shallow burial, energy It has the advantages of high density and no pollution after burning. With the deepening of gas hydrate research, especially the development of gas hydrate mining technology research, the application prospects of gas hydrate technology in natural gas storage and transportation, mixed gas separation, etc. are increasingly emerging. In the research of gas hydrate simulation experiment, the simulation experiment research of gas hydrate formation, decomposition conditions and kinetics is the basis and pre...
