- F25J2250/30—External or auxiliary boiler-condenser in general, e.g. without a specified fluid or one fluid is not a primary air component or an intermediate fluid
- F25J2250/42—One fluid being nitrogen
Definitions
- part of the liquid flowing down in the low-pressure column 5 is removed as nitrogen fraction 20, brought to pressure in the liquid state (14 bar in the example) (pump 21) and via line 22 through the subcooler 15 to a product evaporator 23.
- the nitrogen 24 evaporated under a pressure of 13.4 bar is heated in the main heat exchanger 2 and discharged as a high-purity pressure product 25. If necessary, it can be further compressed in the gaseous state.
- the high purity pressurized nitrogen product 25 has a total contamination of 10 ppb (including carbon monoxide).
