Abstract:

The rapid formation of gas hydrate is key to the application of gas hydrate technology in the fields of natural gas transportation and storage，mixture gases separation，wastewater treatment，cool storage by hydrate，aqueous solutions concentration，etc. The gas hydrate formation mechanisms are introduced in this paper. And the methods and technologies on how to promote and accelerate the formation of gas hydrate are systematically summarized based on the latest research reports. The advantages and drawbacks，as well as application prospect of each method proposed for accelerating hydrate formation are discussed and prospected.
