Description

Description of the invention

The useful model refers to means of natural gas transportation, namely, to elements of transport equipment.

There are many designs of shipping containers for sea, land and air 70 vehicles.

Sea containers have different designs and sizes from Z to . According to their purpose and design, they can be universal, specialized, refrigerated (isothermal), for transporting liquids (oil, alcohol, etc.). Containers with a width of 243 x 8 mm and markings , 18, TA, and I are mainly used for sea transportation (Standard ISO 830-1981 "Cargo container! - Terminology"; Addendum to

Rules for transportation of goods in sea containers by sea transport - RD 31.11.21.18-961.

The most common 20 (1C) and (1A) sea containers (Container!: Reference /F.A. Pladys, V.A.,

Shkurin, G.Z. Surmaev; Ed. V.A. Skin M: Mashinostroenie, 1981. -191 p.).

All types of containers have constant technical characteristics, a special design that ensures that the cargo is transported by one or several types of transport without intermediate unloading of the cargo from the container.

By design, containers can be open, closed and tank containers.

An open container is a cargo container, the design of which does not include one or more main elements: the roof, end or side walls (parts thereof). If necessary, open places in the container are closed with a tarpaulin, synthetic film or other insulating materials. For stacking, overloading and fastening, the container has parts located at its corners - fittings.

The disadvantages of such a container are that it does not reliably protect the cargo from the influence of the external environment. Another significant disadvantage of such containers is that they are rectangular and it is impossible to transport gas under pressure in them. For the transportation of compressed gas, the container must look like a sphere or a cylinder with spherical ends. However, with such forms, containers cannot be grouped into blocks and tiers.

A tank container for the transportation of liquids (oil, gasoline, liquefied gases) is an open container, made in the form of a rectangular metal frame (which includes elements that protect the tank, an end frame and other elements to withstand loads, but not intended to contain cargo and not transmitting static and dynamic loads that occur during lifting, overloading, fixing and transportation of a tank container), in the design of which one or more main elements are not provided: the roof, end (side) walls or their parts. The tank itself is made of carbon steel, rigidly connected to the larger elements of the container frame and installed on a metal foundation. The tank container is equipped with fittings. (Container: Directory /F.A. Pladys, V.A. Shkurin, G.Z. Surmaeev; Edited by V.A. Shkuryn. M:

Mechanical engineering, 1981. -191S.|.

The containers have a rectangular shape, they can be grouped into large blocks of 100...150 pieces and stacked in several tiers.

In addition, containers do not have insulation and therefore do not protect cargo from weather conditions and damage.

The internal volume of the container is used irrationally.

The closest analogue of the utility model is a closed standard marine cargo metal container, which contains a body with corner fittings for fastening the container to other containers and to the body of a container ship, and a door that closes tightly and provides protection of cargo from the environment.

However, it is clear that such containers are not suitable for transporting compressed natural gas.

The task of the useful model is to create inexpensive modules for sea transportation of compressed natural gas by container ships.

The task is solved by the most expedient design of the existing standard sea container, inside which containers with compressed gas are placed in a certain, most rational way. 60 Such a transport module containing compressed natural gas (Sotrgezzedy Mashga! SAZ - SMO) or

The SMO-module consists of a standard marine rectangular container with gas-tight doors, in which the walls are protected by thermal insulation to maintain an operating temperature of 15...20"С., and the internal space is filled with horizontally located cylindrical high-pressure containers with spherical 65 ends of various volumes , placed in a cassette with fixing frames, perpendicular to the longitudinal axes of the containers, interconnected by a system of pipelines and rigidly fixed to the container body, and the dimensions of the containers are chosen in such a way as to make the most rational use of the volume of the container, which is filled with inert gas.

Fig. 1, 2 shows a transport CMO module for transporting compressed natural gas consists of a standard 20-foot sea container 1 with a gas-tight door 2, in which in a cassette with fixing frames C in a certain order (various options can be used) there are cylindrical high-pressure containers of various volumes and sizes with cylindrical ends 4, 5, b. Cassette with fixing frames C is rigidly fixed to the body of the container 1 and installed in such a way that the fixing frames are perpendicular to the longitudinal axes of containers 4,5,6. Containers 4, 5, 6 are connected to each other by the pipes of the local cargo system 7, which is connected to the pipes of the trunk cargo system 8 of the container ship. The walls 75 of container 1 have thermal insulation 9, and its interior is filled with inert gas. Containers

The SMO-module is equipped with a shut-off valve 10. The SMO-module is equipped with corner fittings 11 and quick-disconnect connections 12 from the outside.

To connect the sections of the main pipelines of each SMO-module into a single system of main pipelines of the container ship, all walls of the SMO-modules are installed.

From the blocks, compressed gas is supplied through pipes of smaller diameter to each SMO-module. Distribution of gas in high-pressure containers is carried out with the help of a local cargo system, which is installed in each SMO-module.

The CMO-module is loaded with compressed natural gas as follows. Purified natural gas under pressure, which is in the gas field (approximately 20...25MPa) and which is sufficient for gas compression, is supplied through the high-pressure pipeline from the field to the main high-pressure cargo system of 8 container ships. SMO-modules, placed on the deck and in the holds of the container ship and fixed with the help of corner fittings 11, are combined into blocks of 100...150 pcs. The high-pressure pipes of the main pipelines 8 from each SMO-module form a single cargo system of the main pipelines of the container ship with the help of quick-disconnect connections 12. From the main pipelines 8, gas is supplied to local pipelines 7, through which it enters high-pressure containers of various sizes 4, 5, E, located in a cassette with fixing frames 3.

To maintain an operating temperature of 15...20"С, the inner surface of container 1 is equipped with thermal insulation 9, and for fire safety, the internal space of the SMO-module is filled with inert gas.

In order to prevent emergency situations and ensure safe maritime transportation of compressed natural gas, each container of the SMO-module is equipped with a shut-off valve 10, and tightness is ensured by 4 gas-tight doors 2 of container 1.

Unloading of compressed natural gas into the gas transportation system or underground gas storage at the port of destination is carried out in the same way as loading. Loading or unloading of all SMO-modules is carried out simultaneously.

The efficiency of natural gas transportation in SMO-modules is confirmed by the following calculations.

Take, for example, the container ship "Maeg5kK Yuaezap" with a deadweight of 67,470 tons, a length of 294.1 m, a capacity of 5,089 TE and a speed of 26 knots, which can simultaneously transport more than ZOmln. mi of gas at atmospheric pressure. 20 According to calculations, the price of transporting natural gas by this container ship on the sea line Shkikda port (Algeria) - Golitsyn gas field (Crimea), with a length of 1500 nautical miles (2778 km), will be 38 0050/1000 m3 or 1.37 О05ОЛ 000mU per 100 km, which in It is 5 times cheaper to transport gas through a traditional gas transportation system (the average rate of transit on gas pipelines of European countries in 2009 is 7.04 О05ОЛ ом вв Per 10 Окм).

In addition, due to the diversification of gas flows, Ukraine's energy independence will increase. bo b5 p x 6.0 ul SHE II U U A LY Mu MI sklrzhujy Shum la DY
