An equipment comprise (a) air compressor, (b) a pair of column for removing CO2 and H2O in compressed air, (c) heatexchanger for cooling compressed air to ultralow temp., (d) N refining tower; liquefy a portion of cooled air and maintain stagnant N as gas, (e) liq. N storage tank, (f) the 1st inlet of inflow derives liq. N in tank to refining tower for use as a cryogen of liquefaction of compressed air, (g) the 2nd inlet of inflow; derives liq. N in tank to heat- exchanger to be operated as cryogen in the heat-exchanger and (h) outlet for N exhausting; exhausts gasified N as product from the refining tower. |
