摘要:
A gas storage system formed of a continuous pipe wound in plural layers, each layer having plural loops. The pipe may be distributed within a container, which may serve as a carousel for winding the pipe and as a gas containment device. When containers, each containing a continuous pipe are stacked upon each other, the weight of upper containers may be born by the walls of lower containers, thus preventing lower layers of pipe from suffering stresses due to crushing by upper layers. A method of transporting gas to a gas distribution facility including obtaining a supply of gas at a gas supply point remote from the gas distribution facility, injecting the gas into a continuous pipe bent to form plural layers, each layer including plural loops of pipe, transporting the continuous pipe along with the gas to the gas distribution facility preferably in a ship and discharging the gas at the gas distribution facility. It is preferred that cooling of the pipe during discharging of the gas be conserved so that during subsequent filling the pipe is initially cool. Also, in a further aspect of the invention, during filling, the gas pressure should be maintained as constant as possible for example by controlled release of an incompressible liquid from the pipe as the pipe is filled with gas. Energy from the incompressible liquid may then be recovered or dissipated outside of the pipes.

A gas storage system (11) formed of a continuous pipe (10) wound in plural layers, each layer having plural loops. The pipe may be distributed within a container (12), which may serve as a carousel for winding the pipe and as a gas containment device. When containers, each containing a continuous pipe, are stacked upon each other, the weight of upper containers may be born by the walls (16, 18) of lower containers, thus preventing lower layers of pipe from suffering stresses due to crushing by upper layers. A method of transporting gas to a gas distribution facility including obtaining a supply of gas at a gas supply point remote from the gas distribution facility, injecting the gas into a continuous pipe bent to form plural layers, each layer including plural loops of pipe, transporting the continuous pipe along with the gas to the gas distribution facility preferably in a ship (62) and discharging the gas.

摘要:
The invention relates to a method for reducing the emission of carbon dioxide into the atmosphere and to a tank for carrying out the method. According to the method, carbon dioxide, which was created as a result of a combustion process, is separated from the gas. The carbon dioxide is then brought to a pressure of at least 10 bar in absolute terms, preferably at least 15 bar in absolute terms, mostly preferably at least 18 bar in absolute terms, and is cooled to a temperature of up to -10°C, preferably of up to -20°C. Preferably, the temperature of the liquefied carbon dioxide is up to -40°C. The temperature of the liquefied carbon dioxide, during the transport in a tank, is especially preferably between -25°C and -35°C. The relatively high pressure of, for example, 18 bar in absolute terms requires the provision of tanks having relatively thick walls. However, the high pressure allows for a relatively high proportion of hydrogen and nitrogen to be accepted in the carbon dioxide gas. Thus, it is not necessary to separate nitrogen and hydrogen from carbon dioxide to a large extent prior to liquefaction, which would also cause a separation of carbon dioxide according to the available prior art.
