UsersC-1712 Present C-1711 air flow = 131KN3/H, so theoretical power required = 18MW/H

C-1713 steam consumption = 48T/H ( + 0.84ata), so power recovery = 8.2MW/HPresent AX711 = 1.8MW/HSo, C-1712 power recovery = 18 - ( 8.2 + 1.8 ) = 8MW/H

Item Conc FlowPSA purge 5% 50 Nm3/HIG 0.42% x Nm3/H

Final gas <1% x + 50 Nm3/H

Balance equation(50 * 5) + (x * 0.41) = [1 * (x+50)]

x = 350Nm3/H

So flowmeter selection range = 0 to 500Nm3/H
