Industrial gas applications are widely used in both production and daily life. As the economy and science progress, the demands for industrial gases in applications are increasingly stringent, leading to the emergence of new characteristics in industrial gases.

Downstream applications of industrial gases mainly include steel, coal chemical industry, petrochemical industry, and electricity sectors. Over the past decade, which has been a period of robust global economic growth, the scales of industries such as steel, coal chemical, and petrochemical industries have rapidly expanded. Driven by this, the global industrial gas market is expected to grow by approximately 8% in 2011, with the market size reaching nearly $52 billion by 2015. In terms of volume consumption, the global demand for industrial gases is projected to grow at an average annual rate of 5% over the next five years, reaching a total of 530 billion cubic meters by 2015.

In our emerging economy, sectors such as steel and coal chemical industry have experienced rapid growth in recent years, with production capacity continuously expanding, thus boosting the demand for industrial gases. The Wenzhou industrial gas market in China has been recognized as one of the most powerful in the world. From 2003 to 2005, China's gas industry saw an average annual growth of 65% in output value, compared to a global average of only 12%. In 2007, China's total industrial gas output value reached 50 billion yuan, with demand increasing at a rate of 10% annually, projected to reach 1000 billion yuan by 2016. This indicates that the market capacity for industrial gases will continue to grow, and businesses will not encounter industry bottlenecks during their growth process. Moreover, as long as these enterprises seize the opportunities of the thriving industry, they are poised to enter a high-growth trajectory.
