Successful oxygen generation from the independent integrated air separator

In September 25th, No.8 air separator of Baosteel successfully generates oxygen, the start of operation of the first independent integrated air separator (60,000 m3/h level) in China proclaims the break of monopoly of foreign enterprises in high level air separator manufacturing field.

Through technology import and absorption and independent innovation, Baosteel has accumulated profound experiences in air separator construction, operation and maintenance ever since the initial phase project production. The 8 sets of air separators in Baosteel are 30,000 m3/h level (No.1~No. 4) and 60,000 m3/h level (No.5~No. 8), each one is of world class levels of its time.

The profound air separator construction and maintenance experiences of Baosteel contribute greatly to the development of air separator design and manufacture level of China and propel the whole air separator industry upgrade. In 2002, Baosteel cooperated with Hangzhou Oxygen Generator Work and Kaifeng Air Separator Work in the expansion revampment of No.

2 air separator (Capacity 26,000 m3/h) in which Baosteel was in charge of technology in general and the tow suppliers were to manufacture low-temperature equipment. The successful revampment is the first attempt to manufacture a 30,000 m3/h large air separator in China and is a break of monopoly of foreign enterprises.

The air separators manufactured by Hangzhou Oxygen Generator Work and other suppliers soon occupied the domestic market and have since then been exported oversea. Before the construction of No. 8 air separator, Baosteel also built 2 sets of air separators for 2 local enterprises as the responsible party of technologies through the method of technology trade.

All these have built up the experiences for the independent integration of No. 8 air separator

The independent integration of No. 8 air separator is under the leadership and instruction of Baosteel, project engineered by WISDRI Engineering & Research Incorporation Limited and equipment manufactured by Hangzhou Oxygen Generator Work. The project is constructed by SBC and ZheJiang Kaiyuan Construction Company under the supervision of Baosteel Supervision Company. The project construction lasted for 15 months after the first piling in 19th of June, 2007 and was put into operation one month in advance. As the first independent integrated air separator, No. 8 separator has attained world class and owes Independent Intellectual Property Rights in integration technology, control technology and key sequence engineering, crucial equipment localization. The project has directly saved investment for app. 60 million RMB comparing with similar project. The successful operation of No. 8 air separator of Baosteel further improves the air separator design and manufacture level in China and extends the way of localization of large air separators.
