In 1994, China exported a set of 10000m³/h air separation plant to India Esar Steel Company, which adopted the new technology of the fifth generation of air separation, showing to the world that the design and manufacturing level of China's ASU reached the international level at that time, creating a precedent for the export of large air separation unit in China. The first large air separation plant exported in China, to achieve a zero breakthrough in domestic large air separation plant into the international market.
After 2000, there are more than 50 sets of large air separation plant above 1000m³/h exported to the international market so far, of which 30,000, 40,000, 50,000 air separation plant has also been sold to Europe, North America in Germany, Spain and other developed countries, 80,000, 120,000 large air separation plant sold to Iran, Turkey and other countries, which is a big step for China's ASU manufacturing industry.
