Definitions
- the present invention relates to methods and installations for supplying at least one pressurized gas, in particular those used to supply customers with gaseous products (nitrogen, oxygen, argon) from cryogenic separation devices (such as air separation devices, designated ASU) which are backed up by cryogenic storage.
- gaseous products nitrogen, oxygen, argon
- cryogenic separation devices such as air separation devices, designated ASU
- the invention also applies to installations for the supply of other cryogenic liquids such as hydrogen, helium, carbon monoxide.
- the invention is particularly applicable to methods of supplying a gas from several industrial installations.
- EP-A-0452177 An emergency vaporization device is illustrated in EP-A-0452177 where liquid nitrogen from a storage is vaporized in an exchanger by heat exchange with ambient air.
- EP-A-0628778 describes a storage of cryogenic liquid, the liquid of which is pumped and then vaporized in a vaporizer before being sent to the customer.
- the exchanger can use as circulating fluid to vaporize the pressurized liquid, for example air, steam, hot water, combustion fumes.
- the time necessary for the emergency system to reach, in a stable manner, 100% of its capacity is of the order of 5 minutes which decompose in 1 to 2 minutes to start the pump and 2 to 3 minutes to warm up the vaporization exchanger.
- a judicious choice of architecture and arrangements of the various elements allows this time to be reduced to approximately 3 minutes.
- this time of 3 minutes is still too long vis-à-vis the constraints of pressure fluctuations authorized in the pipeline: in this case, as described above, a solution consists in installing downstream of the exchanger gas buffer capacities (at 200 bars for example) sized to supply production for 1 to 3 minutes, until the pump and vaporizer system reaches its normal operating speed.
- the disadvantage of this solution is its high price (large volume installed, high pressure, pump to fill the buffer capacities ).
- One of the aims of the invention is to avoid having such costly systems for immediate recovery.
- cryogenic liquid from an appliance which can also be used to supply LOX on the bulk market and therefore whose purity can be determined not only by the 'gas user
- another object of the invention is to allow it to be isolated from the storage and therefore not to pollute it, and to continue or not, depending on the constraints of the client, the production coming from this device, production of other devices is not affected.
- the latter provides a method of supplying a gas under pressure by vaporization of a cryogenic liquid from at least two cryogenic separation devices, each device comprising a heat exchanger and a column system where, in each apparatus: a) a compressed and purified gas mixture is cooled in the heat exchanger to produce a compressed, purified and cooled gas mixture b) the compressed, purified and cooled gas mixture is separated in the column system c) a cryogenic liquid is withdrawn from the column system, and in a first operating mode a first part of the cryogenic liquid is vaporized under pressure in the heat exchanger to supply a part of the gas under pressure, and d) the gas under pressure is supplied from each apparatus, or the gas under pressure is mixed with the cryogenic separation apparatuses, and where e) according to the first operating mode, a second part of the cryogenic liquids from each apparatus is sent cryogenic separation in a repository, and f) according to the first operating mode, cryogenic liquid is sent from the repository to each heat exchanger
- the second part of the cryogenic liquid is not pressurized upstream of the storage and / or the first part of the cryogenic liquid is pressurized upstream of the heat exchanger for each cryogenic separation device;
- cryogenic liquid is sent from storage to the exchanger of at least one cryogenic separation device, preferably to the exchanger of at least two cryogenic separation devices, and the cryogenic liquid is vaporized in this exchanger (these exchangers) to supply part of the gas under pressure;
- the cryogenic liquid is pressurized downstream of the common storage and upstream of the exchanger; - in the event of a cryogenic separation device stopping, according to a second mode of operation, the common storage feeds a common vaporizer, preferably after a pressurization step, where the cryogenic liquid from the common storage is vaporized by exchange of heat with circulating fluid to supply all or part of the gas under pressure;
- each cryogenic separation device all the gas mixture intended for the separation is cooled in the exchanger by heat exchange with at least one cryogenic liquid and at least one gas coming from the column system; - the first part of the cryogenic liquid is pressurized by means of at least one pump and according to a third operating mode in the event of at least one of the pumps of a cryogenic separation device being stopped, it is increased in order to compensate loss of compressed liquid following the stopping of this pump, the second part of the cryogenic liquid sent to storage in relation to the flow rate when the pump is running and in the event that there remains a pump in the device in on the cryogenic liquid flow from the column system is increased and sent to the exchanger of this cryogenic separation device compared to the flow when the pump is running; - if at least one pump of a cryogenic separation device is stopped, the first part of the cryogenic liquid is increased relative to the flow rate when the pump is running for at least one other air separation device, the pump (
- the second part of the cryogenic liquid sent is reduced from at least one cryogenic separation device to the common storage relative to the flow rate when the device is in operation, preferably to zero, the first part of the cryogenic liquid sent to the exchanger is increased relative to the flow rate when the apparatus is in operation for at least one cryogenic separation apparatus remaining in operation;
- cryogenic liquid is sent from the storage to an emergency vaporizer.
- pressurization means are used to pressurize the liquid coming from the storage and intended to be vaporized in the exchanger of at least an apparatus for cryogenic separation and for pressurizing the liquid coming from the storage and intended to be vaporized in the vaporizer, these means of pressurization can operate permanently since they are used both when the apparatus is in working order (first mode of operation with vaporization of liquid sent directly and indirectly to the exchanger) and off (second mode of operation with vaporization of liquid in a vaporizer replacing the gas produced by at least one device).
- an installation for supplying a gas under pressure by vaporization of a cryogenic liquid from at least two cryogenic separation devices, each device comprising a heat exchanger and a column system comprising, in each apparatus: a) means for sending a compressed and purified gas mixture into the heat exchanger to produce a compressed, purified and cooled gas mixture b) means for sending the compressed, purified gas mixture and cooled to the column system c) means for withdrawing from the column system a cryogenic liquid, and means for sending at least a first part of the cryogenic liquid under pressure to the heat exchanger to supply a part of the gas under pressure d ) optionally means for mixing the pressurized gas from at least two cryogenic separation devices to supply the pressurized gas and comprising
- the installation does
- a pressurization means downstream of the column system and upstream of the exchanger preferably having an outlet connected to both the exchanger and the common storage and / or an inlet connected to the column system and the storage;
- a common vaporizer means for supplying the common vaporizer from the common storage, preferably pressurization means downstream of the common storage and upstream of the common vaporizer and means for allowing a heat exchange with a circulating fluid and the cryogenic liquid in the vaporizer;
- the same pressurization means are connected downstream of the common storage and upstream of the common vaporizer and to at least one exchanger of a cryogenic separation device (typically to the exchanger of each cryogenic separation device).
- cryogenic liquid vaporized in the common vaporizer comes only from the common storage.
- a cryogenic liquid pipe can connect the column system with the heat exchanger without going through the common storage and a cryogenic liquid pipe can connect the column system and the heat exchanger to through common storage.
- the installation may include means for regulating the flow rates of liquid sent from at least one cryogenic separation device to the common storage and / or means for regulating the flow rates of liquid sent from the common storage to the exchanger of said separation devices cryogenic.
- the vaporizer is adapted to allow the exchange of heat between the cryogenic liquid and a circulating fluid which is not intended for cryogenic separation, such as steam or atmospheric air.
- the separation device produces liquid which vaporizes in an exchanger, part of the liquid being sent directly to the exchanger and the rest being sent to the exchanger through a storage .
- the liquid is pressurized by at least one pump for the liquid sent directly to the exchanger and by at least one other pump for the liquid coming from the storage.
- This same at least one other pump also serves to pressurize the liquid sent to the vaporizer in the event of a second operating mode and thus the at least one other pump is in permanent operation according to the first and second operating modes.
- the common storage can be inside a cold box of one of the separation devices.
- FIGS 1 and 2 are schematic drawings of an embodiment of an installation according to the invention.
- four air separation apparatuses A, B, C, D supply gaseous oxygen under pressure to at least one common customer.
- the four devices are substantially identical and each includes a main heat exchanger 1A, 1B, 1C, 1D and a double column comprising a medium pressure column 2A, 2B, 2C, 2D and a low pressure column 3A, 3B, 3C, 3D.
- the liquid oxygen flows 4A, 4B, 4C, 4D withdrawn from each ASU are substantially identical.
- each device A Compressed and purified air is cooled in the exchanger 1A by heat exchange with at least one gas from the low pressure column 3A and liquid oxygen 4A.
- the cooled air is sent to the medium pressure column 2A in gaseous form.
- Part of the air is liquefied by heat exchange with the liquid oxygen which vaporizes and is then directed to the medium pressure column and / or to the low pressure column.
- the cold behavior of the device can be ensured by any known means, such as a Claude turbine and / or a blowing turbine and / or a nitrogen turbine and / or by bottle feeding.
- the usual reflux rise lines between the medium and low pressure columns do not appear in the figures, as do the withdrawals of nitrogen-enriched fluids.
- liquid oxygen 4A is withdrawn from the bottom of the low pressure column 3A and divided into two.
- a first part of the liquid oxygen 4A for example 80% of the withdrawn flow is compressed by, for example, two pumps in parallel 7A, 8A which are advantageously each dimensioned at 50% of the capacity of a train each of which receives half of the first part of the liquid oxygen and which each work for example at 80% of their capacity, that is to say in our example at 40% of the liquid oxygen capacity of the separation unit.
- the two pumps 7A, 8A can be replaced by a single pump whose capacity would then be for example 100% of a train and which pressurizes all the first part of the liquid oxygen.
- the flow of pumped liquid oxygen is sent via line 9A to exchanger 1 A where it vaporizes to form gas under pressure 10A which can be addressed to the customer.
- This gas typically joins the outlet gases 10B, 10C, 10D from other devices B, C, D.
- the common line can be replaced by a dedicated line for each train.
- the storage is thus continuously supplied by all (or at least a part, the distribution given being only one example) of the ASUs in normal mode, and its pumps 20 and 22 are therefore constantly in “process” operation, close to their normal diet. They redistribute the liquid to each ASU in the same proportions as this liquid came from each ASU (in our example 20% of the liquid oxygen drawn off by ASU). In this way the liquid which vaporizes in the exchanger 1 constitutes 100% of the flow of oxygen withdrawn, of which 80% comes directly from the pumps 7,8 and of which 20% has passed through the storage 12 and the pumps 20, 22. These pumps 20, 22 are thus in operation for immediate resumption in the event of an ASU stopping, in which case they will immediately pass into “emergency spraying” function (whereas with the operation which has just been described, they are in the first operating mode).
- the pumps 20 and 22 are always at the same speed 80%, and the liquid pumped by these pumps 20 and 22 is redistributed always in the same way as it was brought from each ASU, ie in our example 50% of the flow of oxygen drawn from ASU A to ASU A of 7A, and 10% of the flow of oxygen drawn to each of the others. If all the pumps of the same device stop, then transfer
- the pumps 7 and 8 of the other ASUs are set to 50%, thus making each ASU “isolated” from the storage and there is no longer any need to pass liquid to storage 12 through the pipe 6.
- the pumps 20 and 22 of the storage 12 then pump liquid 14 taken from the storage reserve 12.
- the pumped liquid vaporizes in the emergency spray 34. They then consume the storage liquid, whereas in the operations previously described, they only pumped the same amount of liquid as that coming from the ASUs, so that the level of liquid in the storage does not drop substantially.
- the fact that the pumps 20, 22 were already in operation (and close to their full speed) makes it possible to ensure almost immediate recovery by the emergency vaporizer, without additional investment of the high pressure buffer storage type, etc.
- Each air separation device preferably has its cold box, the storage being located inside one of these cold boxes or having its own insulation.
- an air separation device has a single cryogenic liquid pump, when this pump stops, all the liquid is sent to the common storage, pumped by pumps 20, 22 or a pump single and sent to the cold end of the exchanger of the separation device whose pump stopped to supply the production of this ASU.
- the installation in Figure 2 includes all the elements of Figure 1 but differs from it in the following way:
- the liquid sent to the common storage 12 by the common line 6 does not come from the lines 4A-4D bringing the liquid to the pumped dedicated 7A, 8A, but dedicated lines 30A-30D connecting the tank of the low pressure columns 3A-3D with the common line 6.
- dedicated lines 30A-30D connecting the tank of the low pressure columns 3A-3D with the common line 6.
- cryogenic liquids of the lines 4A and 30A have substantially the same composition.
- Dedicated lines connecting each ASU with storage can replace the common line 6.
- the pressurized, vaporized and mixed liquid to form the pressurized gas can be nitrogen or argon.
- the column system can include a conventional double column, a double column with a double vaporizer in the low pressure column or a triple column.
- An argon column can also be present on at least one of the devices.
- Oxygen gas can vaporize in the main exchange line of the separation device or can vaporize in a dedicated exchanger by heat exchange with air.
- Oxygen gas can vaporize in the main exchange line of the separation device or can vaporize in a dedicated exchanger by heat exchange with air.
