The method of transporting natural gas from the place of production to the place of its use

 

(57) Abstract:

The invention relates to oil and gas industry and can be used in the development and exploitation of gas fields, namely for transportation of natural gas, including associated. The technical result of the invention is to improve the efficiency of gas transport and the reliability of the method. The process is carried out by pumping gas into the hollow vessel, placed in the body of the airship, the lifting force which is generated by natural gas, and during the return of the airship is due to the filling of containers other gas is that the gas pressure inside the hollow of the tanks is controlled by a pressure regulator configured to force exceeding the lifting force of the gas transported, and some of its natural gas used as fuel to create the driving force of the airship when delivered to the consumer, and when letting off the natural gas to operate its throttling using excessive pressure to generate the energy required to return the airship to the place of production.

The invention relates to oil and gas industry and can be used for the development of the CSOs.

The prior art method of transportation of gas, for example natural, from the place of production to the place of its use by air in the hollow body of the airship, including inside of hollow containers, and the carrying power of the body is created with natural gas, and during the return of the airship on the way back to create a lifting force capacity is filled by another gas (see DE 1945608 AND, Appl. 09.09.1969,, publ. 14.12.1972 year).

The disadvantage of this method is low efficiency gas transportation because of the need of energy to create the driving force of the airship as for the delivery of gas to the consumer, and delivery of the airship to the place of production, i.e., return it, and low reliability, because there is a need to control the pressure inside the hollow containers.

The present invention is to increase the efficiency of gas transportation from the place of production and the reliability of the method.

This is achieved by the fact that in the method of transporting natural gas from the place of production to the place of its use, including the pumping of gas into hollow vessels, placed in the body of the airship, the lifting force which is generated by natural gas, and during the return of the airship hollow containers controlled by the pressure regulator, configured to force exceeding the lifting force of the gas transported, and some of its natural gas used as fuel to create the driving force of the airship, necessary for delivery of air by the user, and when the release of natural gas from the airship at the site of its use exercise its throttling using excessive pressure to generate the energy required to return the airship to the place of production.

The method is as follows.

Gas selected from gas wells, training that includes separation from gas impurities directly on the field, injected into a hollow vessel, placed in the enclosure soft (mostly from polymeric materials) airship. The lifting force of the airship is generated with natural gas, whose density less than the density of air. For example, the density of air is 861 kg/m3and the density of natural gas (methane) 424 kg/m3. To stabilize the gas pressure in the tanks, the latter equipped with a pressure regulator configured to force exceeding the lifting force of the gas transported (both natural and the other is the time, moreover, some of its natural gas used to create the driving force of the airship. With the release of natural gas from the airship at the site of its use containers filled with another gas, and the excess gas pressure in the tanks, filled with natural gas, used to generate the energy required to return the airship to the place of production.

The method of transporting natural gas from the place of production to the place of its use by injection into hollow vessels, placed in the body of the airship, and a lifting force is generated by natural gas, and during the return of the airship on the way back to create a lifting force capacity fill another gas, wherein the gas pressure inside the hollow of the tanks is controlled by a pressure regulator configured to force exceeding the lifting force of the gas transported, and some of its natural gas used as fuel to create the driving force of the airship, necessary for delivery of air by the consumer, and with the release of natural gas from the airship at the site of its use exercise its throttling using excessive pressure to generate the energy required to return dir is

FIELD: aircraft aerostatic transportation systems.

SUBSTANCE: system consists of large-size separable container and transport module. Container is provided with tank in form of envelope for compressed gas, flexible body filled with light gas and flexible framework with system of units for fastening on transport module. Container accommodates gas tank whose alignment and holding relative to center of container are provided by system of intermediate envelopes and diaphragms. Gas space formed by said system of intermediate envelopes and diaphragms do not communicate and are filled with light gas under pressure. Module includes housing, power plant with air intake and gas-turbine drive - power unit, fuel tank, cruise engines, pitch control system, cab for crew, cargo compartment, system to connected module with container and landing gear. Housing of module is formed by rigid tubular framework. Spaces between framework members and flexible envelope are filled with cylinders containing light gas. Concave surface of envelope providing semi-flush position of large-size container is covered by additional envelope, ballast gas space being formed between housing envelope and additional envelope.
