Definitions

  • the present invention relates to a process for producing oxygen and / or nitrogen gas under pressure and at least one liquid product by means of an installation comprising a simple air distillation column provided with a cycle nitrogen refrigerator in which the air to be treated is compressed to a first pressure at least equal to the pressure of the single column, and at least part of the air is boosted up to a high pressure significantly higher than the single column pressure.
  • a process of this kind is known from GB 2,252,616A, in which only part of the air is boosted at a higher pressure than that of the single column.
  • the boosted flow does not condense and is expanded by a turbine before being sent to the column, hence an inefficient operation of the exchangers.
  • the main compressor and the nitrogen cycle compressor of this installation can in particular be constituted by a single machine.
  • FIGS. 1 and 2 schematically represent, firstly and secondly, an embodiment of the installation according to the invention.
  • the installation shown in Figure 1 is intended to produce pressurized gaseous oxygen, pressurized nitrogen gas, liquid oxygen and argon. It essentially comprises: a main air compressor 1 provided with a refrigerant 2 with atmospheric air or water; an adsorption purification device 3; a 4-turbine blower assembly 5 having the two wheels wedged on the same shaft, the blower also being provided with a coolant 6 air or water; a heat exchange line 7; a simple air distillation column 9; an impure argon production column 10 coupled to the previous one; a sub-cooler 11; storage 12 of liquid nitrogen and 13 of liquid oxygen under atmospheric pressure; pumps 14 for liquid oxygen and 15 for liquid nitrogen; and a compressor 16 of the refrigeration cycle nitrogen provided with an air or water cooler 17.
  • the simple column 9 comprises a tank vaporizer 18, while the column 10 comprises a head condenser 19.
  • the installation also includes expansion valves 20 to 24.
  • the air compressors 1 and cycle nitrogen 16 are combined in a single rotating machine.
  • the incoming air is compressed between 5 and 10 bars at 1, cooled to around room temperature at 2, purified with water and carbon dioxide at 3, and fully boosted at 4 to a high pressure of the order of 6.5 to 13 bars.
  • the pressurized air After pre-cooling in the vicinity of the ambient temperature at 6, the pressurized air enters the hot end of the heat exchange line 7 and is cooled to an intermediate temperature, where 60 to 80% of its flow has come out of the exchange line, turbinated at 5, which relaxes them substantially to the pressure of column 9, called low pressure, between 1.3 and 2 bars, then reintroduced into the exchange line, cooled to the end cold thereof, cooled again at 11, and introduced at an intermediate level into column 9 via a pipe 25.
  • the non-turbinated fraction of the pressurized air continues to cool and is liquefied in the cold part of the exchange line. It is then sub-cooled in 11. Part of this air is relaxed at the pressure of column 9 at 20 and introduced at an intermediate level thereof, while the rest of this air is expanded at 21 and feeds the head condenser 19 of column 10, to be vaporized there, then is returned to column 9 in gaseous state.
  • the installation's nitrogen refrigeration cycle is supplied with practically pure nitrogen produced at the top of column 9, partially reheated at 11 and reheated to room temperature at 7.
  • a fraction of this low pressure nitrogen can be recovered by as a product via a line 26, and the rest is compressed at a medium pressure, which is the high pressure of the cycle, by the compressor 16, then brought back to the vicinity of the ambient temperature at 17.
  • a portion of the medium pressure nitrogen can be recovered as a product via a pipe 27, and the rest is cooled to the cold end of the exchange line up to the vicinity of its dew point, then is condensed in the vaporizer 18 of column 9.
  • Part of the condensed nitrogen is pumped at 15 at a high production pressure of the order of 7 to 40 bars, and the liquid nitrogen under this high pressure is vaporized in the heat exchange line by condensation of the pressurized air, warmed to room temperature, then recovered as a product via a line 28.
  • the rest of the condensed nitrogen is sub-cooled at 11, then, partially, expanded at 22 and introduced under reflux at the top of the column 9, and, for the rest, expanded to atmospheric pressure at 23 and introduced into the liquid nitrogen storage 12.
  • the latter can be supplied with liquid nitrogen taken from the top of the column.
  • An impure nitrogen gas flow constituting the waste gas of the installation, is withdrawn from the column at a level between the injections of liquid nitrogen and liquid air, heated in 11 then in 7 to room temperature, and evacuated via a pipe 29.
  • Liquid oxygen is also withdrawn from the tank of column 9, pumped at 14 at the desired high production pressure, of the order of 2 to 40 bars, vaporized in the cold part of the heat exchange line. by condensing compressed air, warmed to room temperature, and recovered as a product via a pipe 30.
  • Liquid oxygen is also withdrawn from the tank of the column 9 and, after sub-cooling in 11 and expansion to atmospheric pressure in 24, sent to the liquid oxygen storage 13.
  • the tank of column 10 is coupled to an intermediate level of column 9 by two supply and return pipes 31, and this column 10 produces impure argon via a pipe 33.
  • the installation does not include an auxiliary column 10, so that all of the liquefied air in the heat exchange line is, after sub-cooling in 11 then expansion in 20, injected into the simple column 9.
  • the incoming air circuit comprises two blowers 4 and 4A in series, with their respective air or water coolers 6 and 6A, and two air expansion turbines 5 and 5A, respectively coupled to the two blowers .
  • the remaining 60 to 70% of the incoming air is boosted in 4 and then in 4A, to a pressure of the order of 6.5 to 13 bars, then introduced at the hot end of the exchange line. They are cooled to a second intermediate temperature T2 lower than T1, a temperature at which 60 to 70% of this flow is taken out of the exchange line and turbinated in 5A, from where they come out substantially at the pressure of the column 9 via line 32.
  • the pipes 31, 32 meet in a pipe 33.
  • the air conveyed by the latter is again cooled at 11 and then injected into the column, as before, via the pipe 25.
  • the 5A non-turbined pressurized air continues to cool in the cold part of the exchange line, where it is liquefied by vaporization of liquid oxygen and high pressure liquid nitrogen as before.
  • the presence of the two air turbines 5 and 5A improves the performance of the installation, while the nitrogen turbine 34 increases its production of liquid (liquid oxygen and / or liquid nitrogen).
