Air Liquide to Build Low Carbon ASU at Jiangsu Shagang Plant

Air Liquide and Jiangsu Shagang Group have signed a new long-term agreement for the supply of industrial gases in Zhangjiagang City in Jiangsu

Air Liquide and Jiangsu Shagang Group have signed a new long-term agreement for the supply of industrial gases in Zhangjiagang City in Jiangsu Province if China. Air Liquide will invest around 100 million euros towards the construction of a world-scale Air Separation Unit on the site, where it already operates two other ASUs. Designed to use low carbon energy, this state of the art plant will allow to significantly reduce CO2 emissions over time. This new ASU will also be a new source of krypton and xenon to address the growing demand of the Electronics industry, as well as other air gases for our industrial merchant activity in China. Under a 20 year-long contract, Air Liquide will build, own and operate a new state-of-the-art ASU with a daily capacity of 3,800 tonnes of oxygen. It is the largest single ASU for the steel industry in the world, as well as Air Liquide’s largest ASU in China. When the new unit starts up at the end of 2023, it will bring the total installed oxygen capacity to over 8,000 tonnes per day on the site.

The new ASU is equipped with the proprietary solution AliveTM, an innovation that allows for the storage of up to 60 MW of energy per day, enabling flexibility in the grid and contributing to a higher reliability of gas supply. Replacing old assets installed on the customer site, and using an incremental proportion of low-carbon energy, this new ASU will contribute to a lower carbon footprint for this flagship site, in line with Air Liquide’s journey towards carbon neutrality.

This ASU will be a key source of krypton and xenon for Air Liquide, addressing the growing demand of the Electronics industry. The Zhangjiagang site will also become Air Liquide’s largest liquid oxygen and nitrogen source in China, with its Ultra Purity Oxygen capacity positioning it strategically to support small-and-medium sized customers of liquid and packaged gases, including local hospitals requiring high-purity medical gases, in East China.

Air Liquide in China operates nearly 120 plants and employs close to 5,000 employees.
