Also stopping supply of instrument air source is nitrogen compressor to ensure that switching valve closed; (3) manually shut down the oxygen and nitrogen products, valve DX. 101-106 and products entering and leaving, blowdown valve QO. 115 ~ l18, to prevent the outflow of cooling tower; (4) If the pressure is high on the tower, the tower slightly to open the emergency relief valve on the PF. 137, to prevent overpressure.
