METHOD OF PRODUCTION OF NITROGEN UNDER PRESSURE Russian patent published in 1997 - IPC

Abstract RU 2100717 C1

FIELD: chemical industry, metallurgy for separation of air by low-temperature rectification. SUBSTANCE: part of air after complex cleaning unit is bled and subjected to final compression in compressor of turbo-expander compressor unit 7 to pressure of 13 kgf/sq.cm, after which it is cooled in main heat exchanger to temperature of 293 K and is delivered to suction end of main compressor 1. Nitrogen is delivered to consumer at pressure of first stage of rectification unit. Additional reflux is directed to first stage of rectification without heating. EFFECT: enhanced efficiency. 1 dwg
