Abstract

The invention relates to a method for integrating producing, carrying and distribution of natural gas hydrates, comprising: producing the natural gas hydrates and storing it in the gas storing warehouse of lighter; when the natural gas hydrates is needed, supplying heat to the gas storing warehouse to attain gas storing warehouse; when needing remote transmission of gas storing warehouse, first using trailer boat bring the lighter to the destination, than, supply heat for exporting the natural gas hydrates and distribution; or using the lighter replace high pressure spherical tank as natural gas storing tank to supply natural gas in form of hydrates. Said invention integrates the storing, transmission and distribution of natural gas hydrates; since natural gas hydrates is solid, it is safe while lower energy consumption and cost.

Description

technical field [0001] The invention relates to a method for preparing natural gas hydrate, in particular to a method integrating preparation of natural gas hydrate, storage, transportation and distribution of natural gas. Background technique [0002] Natural gas is an important hydrocarbon, its combustion has little environmental pollution, and it is a clean fuel. Moreover, it has abundant reserves. By 2000, the world's total proven reserves reached 150.19 trillion m 3 . The United States Geological Survey predicted in the 2000 World Oil and Gas Assessment Project that there are still 147.05 trillion m 3 Undiscovered natural gas resources, equivalent to 886 billion barrels of oil. In the next 25 years, the world's proven reserves of natural gas will still be in a period of rapid growth, and the estimated new reserves will be 103.58 trillion m 3 (Xu Zhihong, Wen Hao, etc. Breakthrough and Development of Natural Gas Resources. Development of Green Process Engineering in ...
