Definitions
- the present invention relates to a process for producing gaseous oxygen under pressure as defined in the preamble of claim 1. Such a process is known from document FR-A-2 688 052.
- the pressures shown are absolute pressures.
- condensation and vaporization is a condensation or an actual spray, either pseudo-condensation or pseudo-vaporization, depending on whether the pressures are subcritical or supercritical.
- the object of the invention is to provide a method "pump" offering great freedom of regulation of operating parameters and particularly well adapted, from the point of view of energy consumption specific as well as liquid production, large installations, i.e. producing at least 700 tonnes of oxygen per day.
- the subject of the invention is a process for the production of gaseous oxygen gas of the aforementioned type, in which the first press is the average pressure and part of the air at the first press is sent to the medium pressure column without being relaxed.
- the subject of the invention is also a installation for the production of gaseous oxygen intended for the implementation of the process defined above and comprising the features of claim 7.
- the installation may in particular comprise a single air compressor with n stages, said first compression means being constituted by a certain number p of stages, with p ⁇ n , and said second compression means being constituted by the whole of the compressor.
- the air distillation system shown in Figure 1 essentially comprises: a air compressor 1; an air cleaning device 2 compressed into water and CO2 by adsorption, this device comprising two adsorption bottles 2A, 2B, one of which works in adsorption while the other is in progress regeneration; a fan-blower assembly 3 comprising an expansion turbine 4 and a blower or blower 5 whose shafts are coupled, the blower possibly being equipped with a refrigerant (not represented); a heat exchanger 6 constituting the installation heat exchange line; a double distillation column 7 comprising a medium column pressure 8 surmounted by a low pressure column 9, with a vaporizer-condenser 10 putting the overhead vapor (nitrogen) from column 8 in heat exchange relationship with the tank liquid (oxygen) of column 9; a liquid oxygen tank 11, the bottom of which is connected to a liquid oxygen pump 12; and a nitrogen tank liquid 13, the bottom of which is connected to a nitrogen pump liquid 14.
- This installation is mainly intended to supply, via a line 15, oxygen gaseous under a predetermined high pressure, which can be between approximately 13 bars and a few tens bars. These are significant amounts of oxygen gaseous, at least equal to around 700 t / day and capable of reach several thousand tonnes per day.
- liquid oxygen drawn from the column 9 tank via line 16 is stored in the reservoir 11.
- a flow of oxygen, withdrawn from this tank, is brought to high pressure by pump 12 in the liquid state, then vaporized and reheated under this high pressure in passages 17 of exchanger 6.
- the heat necessary for this vaporization and to this reheating, as well as to reheating and possibly vaporization of other fluids drawn from the double column, is supplied by the air to be distilled, in the following conditions.
- Compressor 1 is a multi-stage compressor, with n stages. All of the incoming atmospheric air is compressed by the first p stages at medium pressure, which is the operating pressure of column 8, then is precooled in 18 and cooled to around ambient temperature in 19, is purified in one, 2A for example, adsorption bottles, and divided into two fractions.
- the first fraction at medium pressure, representing for example approximately 40% of the flow of treated air, is cooled from the hot end to the cold end of the heat exchange line 6, in passages 20 thereof, up to '' in the vicinity of its dew point, then is directly introduced into the tank of column 8.
- the rest of the purified air in 2A is returned to the inlet of the ( p + 1) th stage of compressor 1 and is compressed by the following stages up to a first high air pressure, significantly higher than the average pressure of column 8, in practice greater than 9 bars.
- the compressed air, precooled in 19A, is again divided into two streams.
- the first flow representing at least 45% of the treated air flow, is boosted to a second high pressure by the booster 5, which is driven by the turbine 4.
- This second high air pressure is between approximately 25 bars and the condensing pressure air by vaporizing oxygen under the high oxygen pressure.
- the first air flow is then introduced to the hot end of exchanger 6 and completely cooled up to an intermediate temperature. At this temperature, a fraction of the air continues to cool and is liquefied in passages 20A of the exchanger, then is partially relaxed at low pressure in a relief valve 21 and partly to the average pressure in an expansion valve 21A and introduced respectively at an intermediate level in the column 9 and at the bottom of column 8. The rest air is relaxed at medium pressure in the turbine 4 then sent directly, via a line 22, at the bottom of column 8.
- the second stream is introduced under the first high pressure in exchange line 6, cooled and liquefied until the cold end of it in passages 20B, expanded in an expansion valve 21B and connected to the current from the expansion valve 21A.
- Low pressure nitrogen is heated in passages 28 of exchanger 6 then recovered via a pipe 29, while the waste gas, after heating in passages 30 of the exchanger, is used to regenerate an adsorption bottle, bottle 2B in the example considered, before to be evacuated via a pipe 31.
- part medium pressure liquid nitrogen is, after expansion in an expansion valve 32, stored in the tank 13, and that a production of liquid nitrogen and / or oxygen liquid is supplied via line 33 (for nitrogen) and / or 34 (for oxygen).
- the installation product in addition to low pressure nitrogen gas from directly from the head of column 9 and oxygen high pressure gas, pressurized nitrogen gas, obtained by vaporization in the heat exchange line a flow of liquid nitrogen taken from line 33 via a pipe 35. This nitrogen vaporization can especially by condensation of the air contained in passages 20A or 20B.
- FIG. 2 The installation shown in Figure 2 is intended to produce gaseous oxygen under pressure high, for example of the order of 40 bars. She understands essentially two air compressors 41 and 42, one apparatus 43 for adsorption purification, a double distillation column 44 consisting of a column medium pressure 45, operating at around 6 bars, surmounted by a low pressure column 46, operating at a pressure slightly higher than 1 bar, a heat exchange line 47, a sub-cooler 48, a liquid oxygen pump 49, a cold blower 50, a first turbine 51 whose wheel is mounted on the same tree as that of the cold blower, and a second turbine 52 braked by an appropriate brake 53 such than an alternator.
- a double distillation column 44 consisting of a column medium pressure 45, operating at around 6 bars, surmounted by a low pressure column 46, operating at a pressure slightly higher than 1 bar
- a heat exchange line 47 a sub-cooler 48
- a liquid oxygen pump 49 a cold blower 50
- a first turbine 51 whose wheel is mounted
- the first stream is directly cooled in passages 62 of the exchange line 47.
- a fraction of this air came out of the exchange line, relaxed at the low pressure in turbine 52, and blown into a intermediate point of the column 46 via a pipe 63.
- the rest of the medium pressure air continues to cool to the cold end of the exchange line, where it is near its dew point and then is sent to the bottom of column 45.
- the rest of the air from the device 43 is compressed at a first high pressure, for example from 16.5 bars, by compressor 42, then enters air cooling passages 64 of the exchange line.
- the blower 50 which provides this compression is driven by the turbine 51, so that none external energy is required. Take in account the mechanical losses, the amount of cold produced by this turbine is slightly higher than the heat of compression, and the excess contributes to keeping cold of the installation. The balance of the necessary frigories for this keeping cold is provided by the turbine 52, or, alternatively, if the oxygen to be produced must have a high purity, by air or nitrogen expansion to medium pressure in a turbine, in a conventional manner.
- the installation can also generate oxygen at a pressure low enough to allow vaporization of oxygen by condensation at the highest process air pressure.
- This oxygen pressure would be less than 8 for example bars.
- a second pump 70 compressing liquid oxygen reduced purity at lower intermediate pressure at 8 bars. This oxygen is vaporized by condensation of a corresponding part of the air supercharged by the blower 50, which only has to supply the heat of compensation for excess cold due to vaporization high pressure oxygen.
- mixed lines have been indicated on the Figure 2 a medium pressure liquid nitrogen pump 71 bringing this nitrogen, withdrawn from column 45, to a intermediate pressure low enough to allow its vaporization by air condensation at the highest process pressure, i.e. 23 bars.
- FIG. 2 Also shown in Figure 2 is a line 72 for the production of liquid oxygen withdrawn from the tank of the column 46, as well as a pipe 72A of production of liquid nitrogen from the head of the column 45.
- FIG. 3 The installation in Figure 3 is a variant of that of Figure 2.
- a fraction of the air coming from the compressor 42 is overpressed by a hot blower 73, cooled in 47 to temperature T2, again boosted by the blower cold 50, reintroduced into the exchange line at a temperature T3 higher than T2, then treated in two different flows from temperature T4, like previously.
- the rest of the air from compressor 42 is cooled in additional passages 74 of the exchange line 47 up to a temperature T5 included between temperatures T4 and T1, and, at this temperature, some of this air has come out of the exchange line, expanded at medium pressure in an additional turbine 75 coupled to the blower 73, then sent to the tank from column 45.
- the rest of the air carried by the passages 74 continues to cool down to the end cold of the exchange line, where it is liquefied and sub-cooled, then is relaxed at medium pressure in a expansion valve 76 and sent in the lower part from column 45.
- the invention is particularly advantageous, from an energy point of view, when the pressure of oxygen vaporization is greater than approximately 20 bars.
