Experimental Study on Gas Hydrates Dissociation in Sands by Depressurization

Article Preview

Abstract:

Depressurization method is a more potential way for gas production from gas hydrates. The behavior of gas hydrates dissociation by depressurization method is observed by the use of an experimental apparatus. The hydrates saturation is tracked by TDR during hydrates decomposition. The decomposition process consist three stages: fast dissociation, stable dissociation and the end. Significantly one of major factors that determine gas production rate by depressurization: degree of depressurization is discussed. t1/2 is used to characterize the hydrates decomposition rate. The greater of degree of depressurization is the faster of the hydrates decomposition rate gets.
