The Hangyang 48000m3/h air separation plant used by Henglu, Shandong, China, was successfully launched on December 16, 2006. The air separation plant was the first set of domestic independent research and development, with independent intellectual property rights and successfully operated successfully. The 50,000-grade chemical high-pressure internal compression air separation device has the characteristics of good safety performance, high reliability, and stable operation and operation. The development of this product has broken through the key technologies such as design, calculation and optimization of complete air separation process, reasonable organization and calculation technology of distillation tower system, design and manufacturing technology of supporting single equipment, computer control and optimization technology of large-scale equipment, making Hangyang Mastered the key design and manufacturing technology for the 50,000-class high-pressure compression air separation plant, which ended the history of China's 50,000-grade air separation completely dependent on imports. The air separation capacity is 232,500 m3/h, the oxygen extraction rate is 99.5%, the argon extraction rate is 76%, and the unit oxygen consumption reaches 0.36 kW·h/m3, all reaching the international advanced level.
It is understood that large-scale air separation plants are now only capable of designing and manufacturing in the United States, Germany, France, Japan, and a few other countries. The realization of 50,000 grade air separation plants will make China's major technological equipment comprehensive development capabilities to a higher level. The level of technology will also drive technological advances in relevant industries, save foreign exchange, save investment costs, and increase international competitiveness.
A few days ago, the Zhejiang Provincial Economic and Trade Commission confirmed and announced 71 items of "The first (set) of products in the key areas of accelerated development of equipment manufacturing in Zhejiang Province in 2007," including 4 provinces of 48000m3/h air separation equipment, including Hangzhou Oxygen Co., Ltd. The products were included in the first domestic (set) product and received 1 million yuan in award funds.
