China's large air separation plant is no longer dependent on imports <br> <br> reporter learned from the Henan Kaifeng Air Separation Group Co., China's self-developed design, manufacture, with independent intellectual property rights of the first set of 53 000 m3 / h large double The compressed air separation unit in the pump has been successfully operated for 20 consecutive days from December 17th after successfully driving in the 500,000 tons/year methanol project of Longyu Coal Chemical Industry in Yongcheng, Henan Province on November 28. This marks the complete localization of China's "50,000-plus" class of super-large air separation devices, ending the long-term dependence on imports. According to reports, air separation equipment is currently a high-tech device at home and abroad, widely used in chemical, fertilizer, smelting and other fields. Previously, only the United States, Germany, and France were able to manufacture such equipment. China's large air separation equipment market has long been monopolized by foreign manufacturers. Before China has not developed the "40,000" class of air separation equipment, the foreign price of this grade is 170% of the domestic; the price of the "60,000" or more air separation equipment is more than 50 million US dollars. The relevant person in charge of Yongmei Group introduced that the company's independent research and development, design, manufacture and complete sets of 10,000-50,000 m3/h air separation projects have been put into industrial operation. The group also has the ability to design and manufacture “60,000†class air separation equipment, laying the foundation for the localization of air separation units of 80,000 to 100,000 or more.
