- this compression means 122 is configured to compress natural gas from 0.35 bar to 1 bar. The natural gas thus compressed is then able to join the compression member 120 and / or the compression device 121, in which (s) it (s) it undergoes a second compression.
- this first operating mode is said to be "at equilibrium”.
- this first mode of operation corresponds to the perfect case in which the quantity of evaporated natural gas present in the head cap 201 in the gaseous state is identical to the needs of the gas consuming appliance (s) 130, 131.
- the valves 150, 151 are closed, and the first and second pumps 210, 220 are stopped.
- the natural gas is thus taken in the gaseous state in the vessel head 201, then sent directly to the compression member 120 and / or the compression device 121, so that its pressure is increased in order to supply the gas-consuming appliance (s) 130, 131.
- FIG. 3 illustrates a second mode of operation of the system 100 according to the invention, this second mode of operation being called "forced evaporation".
- This second mode of operation is implemented when the quantity of gaseous natural gas present in the tank top 201 is less than the needs of the gas consuming appliance (s).
- This second operating mode advantageously makes it possible to generate gaseous natural gas from liquid natural gas in order to be able to supply this (these) device (s).
- the first pump 210 and the second pump 220 are both activated, while the valves 150, 151 respectively arranged on the second pipe 102 and between the sixth pipe 106 and the heat exchanger 110 are closed, so that the gas compressed natural gas coming from the compression member 120 and / or from the compression device 121 is completely sent to the gas consuming appliance (s).
- the second pass 112 of the heat exchanger 110 is not supplied and the natural gas taken from the tank in the gaseous state is sent directly to the compression member. 120 and / or the compression device 121.
- the heat exchanger 170 is in turn fed with natural gas taken from the tank 200 in the liquid state.
- the first pump 210 sucks liquid natural gas into the tank 200, this liquid natural gas passes through the expansion means 182 in which it undergoes a reduction in its pressure.
- this expansion to allow the liquid natural gas to pass from atmospheric pressure, that is to say approximately 1 bar, to a pressure below atmospheric pressure, for example to a pressure of approximately 0.35 bar.
- the first pass 171 of the heat exchanger 170 is supplied with liquid natural gas at low pressure.
- the second pump 220 also sucks liquid natural gas into the tank 200 to directly supply the second pass 172 of the heat exchanger 170.
- the second pass 172 of the heat exchanger 170 is thus supplied with pressurized liquid natural gas. atmospheric.
- a heat exchange then takes place in the heat exchanger 170, between the low pressure liquid natural gas which circulates in the first pass 171 and the liquid natural gas at atmospheric pressure which circulates in the second pass 172 This results in evaporation of the low-pressure liquid natural gas which circulates in the first pass 171 and a sub-cooling of the liquid natural gas at atmospheric pressure which circulates in the second pass 172.
- the sub-cooled liquid natural gas can then be returned.
- the compression means 122 makes it possible to pass the gaseous natural gas from a pressure of about 0.35 bar to a pressure of about 1 bar. Gaseous natural gas thus leaves the means of compression 122 at atmospheric pressure and joins the compression member 120 and / or the compression device 121 in which (s) its pressure is still high in order to be able to use this gaseous natural gas as fuel for the (s) gas-consuming appliance (s).
- the heat exchanger 170 advantageously makes it possible to supply gas consuming devices 130, 131 on the one hand and to store cold in the bottom of the tank 200 on the other hand.
- the storage of sub-cooled liquid natural gas in the tank 200 makes it possible to lower the temperature of the liquid natural gas contained in the tank 200 so as to reduce the evaporation of this natural gas. liquid contained in the tank 200.
- the third operating mode corresponds for its part to an operating mode of the system 100 in which the quantity of natural gas present in the gaseous state in the vessel head 201 is greater than the gas requirement of the gas consuming appliance (s) 130, 131.
- natural gas is taken in the gaseous state from the top of the tank 201 to supply the heat exchanger 110, and more particularly the first pass 111 of this heat exchanger 110.
- the natural gas in the gaseous state captures calories from the gaseous and compressed natural gas which circulates in the second pass 112 as described above.
- the natural gas thus leaves the heat exchanger 110 in the gaseous state and at a temperature higher than the temperature that it exhibited in the vessel top 201.
- This heated gaseous natural gas then joins the compression member 120 and / or the compression device 121 in which it undergoes an increase in its pressure to a value sufficient to supply at least one of the gas consuming devices 130, 131.
- part of this gas Heated and compressed natural gas feeds the appliance (s) consuming gas 130, 131.
- At least one of the valves 150, 151 is open to allow another part of this gaseous natural gas heated and compressed to join the second pass 112 of the heat exchanger 110. It is understood that the part of the heated and compressed gaseous natural gas which feeds the gas consuming appliance (s) 130, 131 is distinct from the other part of this heated and compressed gaseous natural gas which joins the second pass 112 of the heat exchanger 110.
- the gaseous natural gas which circulates in the second pass 112 of the heat exchanger 110 yields calories to the gaseous natural gas which circulates in the first pass 111 of this heat exchanger 110 of so that the gaseous natural gas leaves the heat exchanger 110 and joins the third pipe 103 at a temperature lower than the temperature which it exhibited at the inlet of the second pass 112. It is understood, however, that the natural gas leaves the second pass 112 of the heat exchanger 110 in the gaseous state.
- the third pipe 103 is connected to the bubbling member 140.
- the gaseous natural gas which leaves the second pass 112 of the heat exchanger 110 cools and thus joins this bubbling member 140 and passes into the orifices 142 formed. in the ramp 141 of this bubbling member 140, so that gas bubbles 143 are generated and released in the bottom of the tank 200.
- These gas bubbles 143 are thus found in contact with the liquid natural gas contained in the tank 200 , which leads to the condensation of these gas bubbles which then transform into liquid natural gas which then mixes with the rest of the liquid natural gas present in the tank 200.
- the orifices 142 of the bubbling member 140 are distributed homogeneously over an entire length of the ramp 141, that is to say the longest dimension of this ramp 141, so that the gas bubbles 143 are also distributed in the bottom of the tank 200, thus increasing the contact surface and the temperature difference between each gas bubble and the liquid natural gas contained in the tank 200. It is understood that the release of these gas bubbles 143 tends to increase the temperature of the liquid natural gas contained in the tank 200.
- the second operating mode and the third operating mode are advantageously implemented successively.
- the second operating mode makes it possible to store cold at the bottom of the tank - thanks to the return to the bottom of this tank of natural gas sub-cooled by the heat exchange operated in the heat exchanger 170.
- the temperature of the liquid natural gas contained in the tank 200 is thus reduced, and the increase in the temperature of this liquid natural gas generated by the release of the liquid natural gas.
- gas bubbles 143 via the bubbling member 140 during the implementation of the third mode of operation is controlled.
- the second operating mode makes it possible to store cold in anticipation of an increase in the temperature of the tank. liquid natural gas contained in the tank linked to the release of the gas bubbles 143 by the bubbling member 140 when the system 100 switches to the third operating mode.
- FIG. 5 is a cutaway view of a ship 70 which shows the tank 200 which contains natural gas in the liquid state and in the gaseous state, this tank 200 being of generally prismatic shape mounted in a double hull 72 of the ship.
- the wall of the tank 200 comprises a primary sealing membrane intended to be in contact with the liquefied gas contained in the tank, a secondary sealing membrane arranged between the primary sealing membrane and the double hull 72 of the vessel, and two insulating barriers arranged respectively between the primary waterproofing membrane and the secondary waterproofing membrane and between the secondary waterproofing membrane and the double shell 72.
- Loading and / or unloading pipes 73 arranged on the upper deck of the ship can be connected, by means of suitable connectors, to a marine or port terminal to transfer the cargo of natural gas in liquid state from or to the vessel 1.
- FIG. 5 also shows an example of a marine terminal comprising a loading and / or unloading station 75, an underwater pipe 76 and an installation on land 77.
- the loading and / or unloading station 75 is a fixed off installation. -shore comprising a movable arm 74 and a tower 78 which supports the movable arm 74.
- the movable arm 74 carries a bundle of insulated pipes 79 which can be connected to the loading and / or unloading pipes 73.
- the movable arm 74 can be oriented. adapts to all vessel sizes.
- the loading and unloading station 75 allows the loading and / or unloading of the ship 70 from or to the shore installation 77.
- the latter comprises liquefied gas storage tanks 80 and connecting pipes 81 connected by the underwater pipe 76 to the loading or unloading station 75.
- the underwater pipe 76 allows the transfer of the liquefied gas between the loading or unloading station 75 and the onshore installation 77 over a great distance, for example 5 km, which makes it possible to keep the vessel 70 at a great distance from the coast during loading and / or unloading operations.
- the present invention thus provides a gas treatment system which makes it possible to supply gas consuming devices present on a ship with naturally evaporated gas, with liquid gas which has been forcibly evaporated and also to condense the naturally evaporated gas if the latter. was in excess of the energy demand of the gas consuming appliance (s) of the ship, advantageously at a limited cost.
- the present invention should not however be limited to the means and configurations described and illustrated here and it also extends to any equivalent means and any configuration as well as to any technically operative combination of such means.
