Abstract
The invention relates to a method for the storage of natural gas or coal gas with the ability of working with high temperature between 85DEG C to 115DEG C, low pressure between 4.77 mpa to 1.47 mpa, with the capacity of also being able to make peak regulation. Through constant temperature control for the low temperature liquidized natural gas or coal gas layer in the storing can by heat exchanger, without using high vacuum and multi layered insulation within the storing can, it saves the current insulating technology, simplifies the manufacturing process, and reduces production cost. It allows long time storage of liquidized natural gas or coal gas layer under high temperature or low pressure.
Description
Technical field
The present invention relates to the conveying method of a kind of rock gas or coal-seam gas, specifically relate to the low temperature conveying method of a kind of rock gas or coal-seam gas.
Background technique
Rock gas adopts following method accumulating at present: pipeline transport, its shortcoming are can not store and peak regulation; Liquid tank car transportation, its shortcoming is it to be reduced to-160 ℃, the cost of transportation height, terminal is difficult for long term storage; The transportation of gaseous compressed tank car, its shortcoming is not only uneconomical but also dangerous, can not store by peak regulation.
Summary of the invention
The purpose of this invention is to provide a kind of can store and can peak regulation, can be in higher temperature-85 ℃ to-115 ℃, lower pressure 4.77 MPas to-1.47 MPas to the method for rock gas or coal-seam gas accumulating.
The method of preferred accumulating rock gas provided by the invention or coal-seam gas is, carry out said accumulating with the container that comprises following characteristics: vessel shell, be fixed in the storage tank in the said shell, said container is interior or storage tank is interior or tank battery is provided with heat exchanger, and said container is provided with and fills the cold joint mouth.
In container, be provided with refrigerator in the method for more preferably accumulating rock gas provided by the invention or coal-seam gas.
The invention provides that said refrigerator is a two-stage refrigeration in the method for preferred accumulating rock gas or coal-seam gas.
Said vessel shell is a heat-preservating shell in the method for preferred especially accumulating rock gas provided by the invention or coal-seam gas, and profile is a shipping container shape.
In the method for the most particularly preferred accumulating rock gas provided by the invention or coal-seam gas, be provided with the thermal radiation resistant metallic film in the shell of said heat-preservating shell.
The method of the most particularly preferred accumulating rock gas more provided by the invention or coal-seam gas is characterized in that said storage tank is that two ends are hemispherical cylindrical.
Be provided with the framework of standing tank in the method for another the most particularly preferred accumulating rock gas provided by the invention or coal-seam gas in the said container.
Term among the present invention " falls " and means: normal temperature natural gas in gaseous state or coal-seam gas by usual two-stage system cryogenic treatment, are cooled the temperature to-85 ℃ to-115 ℃, pressure is reduced to 4.77 MPas to-1.47 MPas.
Container in the method provided by the invention is interior or storage tank is interior or tank battery is provided with heat exchanger, and container is provided with and fills the cold joint mouth.By heat exchanger the temperature of low temperature liquid rock gas or coal-seam gas in the storage tank is carried out thermostatically control, storage tank so wherein need not high vacuum multiple layer heat insulation measure of the prior art, saved realization high vacuum multiple layer heat insulation technology, simplified manufacturing process, reduced cost of production, make original liquified natural gas or coal-seam gas-162 ℃ of following accumulatings can be, the long-time accumulating to-1.47 MPas of lower pressure 4.77 MPas in higher temperature-85 ℃ to-115 ℃.
