Definitions
- the invention relates to a method for the production of pressurized nitrogen by Cryogenic decomposition of air in a rectification system containing a pressure column and a low pressure column, wherein in the process feed air in the Pressure column initiated, an oxygen-containing liquid fraction from the pressure column taken out and fed into the low-pressure column, gaseous nitrogen the low pressure column in a top condenser by indirect heat exchange is at least partially condensed with an evaporating liquid, liquid Withdrawn nitrogen from the low pressure column or from the top condenser and is introduced into the pressure column and from the evaporating liquid incurred residual gas is removed from the top condenser.
- the invention is therefore based on the object, a method of the initially mentioned type and to provide a corresponding device that economically work very cheap.
- the pressure column is under a head pressure of, for example, 9 to 10 bar, preferably 9.2 to 9.5 bar operated.
- the operating pressure of Low pressure column is, for example, 5.7 to 6.3 bar, preferably 5.9 to 6.1 bar at the head.
- the evaporation space of the top condenser of the low-pressure column is under a pressure of for example 2.4 to 3.0 bar, preferably 2.6 to 2.8 bar.
- the heating of the residual gas is preferably by indirect Heat exchange with a process gas, in particular carried out with feed air.
- the main heat exchanger can be used, the Cooling of feed air is used.
- Part of the withdrawn from the low pressure column or from the top condenser liquid nitrogen can be recovered as a liquid product.
- the liquid product can, for example, together with the introduced into the pressure column Liquid nitrogen from the low pressure column or from their Top condenser withdrawn and upstream or downstream of a pump be branched, which increases the pressure to at least pressure column pressure serves.
- the invention also relates to a device for obtaining pressurized nitrogen according to claim 4, or according to claim 3 for the Contracting State DE.
- Compressed and purified feed air flows via line 1 in one Main heat exchanger 2 and is cooled there to about dew point.
- line 3 the cold air is supplied to the pressure column 4 of the rectification system, which consists of Pressure column 4, the low pressure column 5 and the top condensers 6 and 7 consists.
- An oxygen-containing liquid fraction (8) from the bottom of the pressure column is in a Subcooler 9 is cooled and to a first part 10 in the low pressure column. 5 initiated.
- a second part 11 of the bottom liquid of the pressure column is in the Evaporation space of a first condenser-evaporator 6 introduced, the Head condenser of the pressure column forms. That in the first condenser-evaporator generated gas 12 is also introduced into the low-pressure column 5.
- a small Amount is removed as rinsing liquid 39.
- gaseous nitrogen 14 is removed and to a first part 15 in the main heat exchanger 2 warmed to approximately ambient temperature and discharged as pressure nitrogen product.
- a second part 17 of the head nitrogen of Pressure column is at least partially in the first condenser-evaporator 6 liquefied.
- the condensate 18 is generated as a return to the head of the Pressure column 4 abandoned (19).
- the second condenser-evaporator connected as the top condenser of the low-pressure column 5 7 is operated with liquid 20 from the bottom of the low-pressure column. This evaporates and is - apart from a small purge 21 - than Residual gas 22 from the evaporation chamber of the second condenser-evaporator deducted.
- Head nitrogen 23 of the low pressure column is on the liquefaction side passed the second condenser-evaporator and at least partially condensed.
- the generated liquid nitrogen serves to a part 25 as reflux for the Low pressure column 5.
- Another part 26 is sucked by a pump 27 and in liquid state brought to about pressure column pressure.
- the liquid pressure nitrogen 28 is guided via the lines 29 and 19 to the head of the pressure column 4. If desired, a part 30 can be obtained as a liquid product.
- the residual gas 22, 31, 32, 33 from the top condenser 7 of the low-pressure column is in Subcooler 9 and main heat exchanger 2 to an intermediate temperature warmed up and working according to the invention in a relaxation machine 34 relaxed.
- the relaxed residual gas 35 is again the cold end of Main heat exchanger supplied (36).
- the warm residual gas 37 can for Regeneration of a device, not shown, for cleaning the feed air or used as a by-product or vented to the atmosphere.
- the Relaxation machine 34 is preferably designed as a turbine and can by any known device to be braked.
- a dissipative Brake 38 is used.
- the head cooling of Pressure column also in the known manner by means of bottom liquid of the Low pressure column done.
- pressure column 4 and low pressure column 5 integrated into a double column and / or the first condenser-evaporator in Swamp low pressure column 4 may be arranged.
- the oxygen-containing liquid Fraction 8 from the bottom of the pressure column is then preferably completely in liquid state of the low pressure column 5 fed (10).
