It is known to produce a gas of pressurized air by vaporization of pressurized liquid in an exchange line of an air separation apparatus by heat exchange with a compressed gas from a cryogenic temperature. Devices of this type are known from FR-A-2688052, EP-A-0644388, EP-A-1014020 and the patent application FR0301722. The energy efficiency of known devices is not excellent because it is necessary to evacuate the thermal inputs related to cryogenic compression.

- the air sent to the turbines is at a pressure higher than the high pressure and comes from the cold booster and / or the booster constituting the dissipation device or forming part of it ( Figures 1 and 3);
- the air at high pressure is overpressed in the cold booster; the high-pressure air is divided into at least two parts, one part being overpressed in the cold supressor and another part (the rest) in the booster constituting the dissipation device or forming part of it (FIG.
- At least one final product is produced in liquid form
- a cryogenic distillation air separation plant comprising: a) a double or triple air separation column, whose column operating at the highest pressure operates at a temperature of so-called medium pressure, b) a line of exchange, c) means to bring all the air to a higher pressure than the average pressure and means to purify it at this high pressure, d) means for sending a portion of the purified air flow into the exchange line for cooling and means for dividing this cooled air into two fractions, e) two turbines and means for sending a fraction of air to each turbine, f) means for sending at least a portion of the expanded air in at least one of the turbines to the medium pressure column of the double or triple column, g) a cold booster, means for sending air, preferably withdrawn at an intermediate point of the main exchange line at the cold booster and means for sending air blown into the cold booster in the main exchange line at an intermediate point upstream of the draw-off point, h) means for pressurizing at least one liquid from one
- the two boosters are connected in series or in parallel and the turbines are connected in parallel.
- the suction temperature of the second booster is greater than the inlet temperature of the turbines.
- a complementary turbine operating in parallel with the turbine of the first blower assembly booster, and equipped with its own energy dissipation system.
- this system will be a su ⁇ resseur followed by a water cooler installed in the hot part.
- “Close in terms of pressure” means that the pressures differ by not more than 5 bar, preferably not more than 2 bar.
- “Close in terms of temperature” means that the temperatures differ by not more than 15 ° C, preferably not more than 10 ° C.
- a su ⁇ resseur is a single-stage compressor.
- condensation includes pseudo condensation.
- vaporization includes pseudo vaporization.
- This invention differs from US-A-5 475 980 in that in Figure 4 (optional turbine 9), the two turbines 8, 32 aspire at very different pressures, the difference being at least 14 bars and in Figure 5, the pressure difference is about 13 bar and a turbine escapes the low pressure, which is penalizing for pure oxygen.
- a flow of air at atmospheric pressure is compressed to about 15 bar in a main compressor (not shown).
- the air is then optionally cooled, before being purified to remove impurities (not shown).
- the clean air is divided in two.
- Part of the air 3 is sent to a booster 5 up to a pressure of between 17 and 20 bar and then the supercharged air is cooled by a water cooler 7 before being sent to the hot end of the main exchange line 9 of the air separation apparatus.
- Sufficient air 11 cools to an intermediate temperature before exiting the exchange line and being divided into two fractions.
- a fraction 13 is sent into a turbine 17 and the remainder, a fraction 15 is sent into a turbine 19.
- the two turbines have the same temperature and suction pressure and the same temperature and outlet pressure but it is obviously possible that these temperatures and pressure are close to each other instead of being identical.
- the two flow turbines are mixed to form a flow 21 of gaseous air which is sent to the column system as will be described with respect to FIG. 2.
- the turbine 19 may be an insufflation turbine leading to the pressure of the low pressure column.
- Another part 2 of the air at 15 bars constituting the rest of the air is cooled in the exchange line at an intermediate temperature higher than the suction temperature of the turbines 17, 19, compressed in a second booster 23 until at about 30 bar and reintroduced into the exchange line 9 at a higher temperature to continue cooling.
- the air 37 to 30 bar is liquefied in the exchange line and liquid oxygen 25 vaporizes in the exchange line, the vaporization temperature of the liquid being close to the suction temperature of the second booster 23.

- a flow of residual nitrogen 27 is heated in the exchange line 9.
- the first booster 5 is coupled with one of the turbines 17, 19 and the second supressor 23 is coupled with the other of the turbines 19, 17.
- the column system of an air separation apparatus is constituted by a medium pressure column 100 thermally connected with a low pressure column 200.
- the medium pressure column operates at a pressure of 5.5 bar but can operate at a higher pressure.
- the gaseous air 21 from the two turbines 17, 19 is the flow rate delivered to the bottom of the medium pressure column 100.
- the liquefied air 37 is expanded in the valve 39 and divided in two, a portion being sent to the medium pressure column. 100 and the remainder at the low pressure column 200.
- Rich liquid 51, lower lean liquid 53 and upper lean liquid 55 are sent from the medium pressure column 100 to the low pressure column 200 after expansion stages in valves and subcooling.
- Liquid oxygen 57 and liquid nitrogen 59 are withdrawn as final products of the double column.
- Liquid oxygen is pressurized by the pump 500 and sent as pressurized liquid 25 to the exchange line 9.
- Other liquids, pressurized or not, can vaporize in the exchange line.
- Nitrogen gas is optionally withdrawn from the medium pressure column and is also cooled in the exchange line 9. Nitrogen 33 is withdrawn at the top of the low pressure column and heats up in the exchange line, after having served to sub-cool the reflux liquids.
- Residual nitrogen 27 is withdrawn from a lower level of the low pressure column and heats up in the exchange line, after having been used to sub-cool the reflux liquids.
- the column may optionally produce argon by treating a flow rate withdrawn in low pressure column 200.
- the air is then optionally cooled and purified to remove impurities and cooled.
- a first portion of the purified air is supercharged in the first booster 5 to a pressure of about 17 bar before being cooled by a water cooler 7.
- the second part 2 of the air at 15 bar is cooled in the exchange line at a temperature below the suction temperature of su ⁇ resseur 23, leaves the exchange line and is divided in two. Each portion of the air is expanded in a turbine 17, 19 before being sent to the medium pressure column 100.
- the hot booster 5 is coupled to the turbine 17 and the cold booster 23 is coupled to the turbine 19.
- the two turbines 17 and 19 are supplied not with air coming from the hot booster but with water. at high pressure.
- the cold booster 23 overpresses all the air from the hot booster 5 and this air is then liquefied.
- the inlet pressure of the turbines is therefore lower than in Figure 1.
- the rest of Figure 2 is identical to Figure 1.
- the hot booster 5 is removed. All air 1 is sent to the exchange line at a single pressure greater than 5 to 10 bars at medium pressure. This air is withdrawn from the exchange line at an intermediate temperature and all the air is su ⁇ ressé at a temperature below ambient to a pressure of 18 bars in the cool su ⁇ resseur 23. Then the air is compressed in two.
- a portion 33 continues cooling to the cold end of the exchange line, liquefies and is expanded to be sent into at least one column of the column system 100, 200.
- the combined flow of air expanded in the turbines 17, 19 is sent to the medium pressure column and is the only gaseous air inlet in the double column.
- the cold booster 23 is coupled to the turbine 19 and the turbine 17 is coupled to an electric generator 61 which can be replaced by an oil brake.
