The cryogenic air separation unit (ASU) of the plant came online earlier this week after round-the-clock efforts of the plant's experts and executives, reported the National Petrochemical Company (NPC).  

The utility required for running the plant was primarily supposed to be supplied from a concentrated unit but after privatization of the unit, it was decided that an ASU unit be constructed in it for supplying utilities such as oxygen.  

The plant is being constructed with 1.65 million tons of annual production capacity at phase II of Asaluyeh, southern Iran.
