Recently, Henan Kaifeng Air Subsidiary Group Co., Ltd. and Shandong Tengzhou Phoenix Fertilizer Co., Ltd. have signed a contract to provide them with a set of 42000m3/h air separation unit. This is another set of large-scale air separation equipment orders undertaken by Kaifeng Airspace following Shandong Hualu Hengsheng 40000m3/h air separation and Henan Yongmei 52000m3/h air separation.
Tengzhou Phoenix is ​​another coal chemical production base following Inner Mongolia 3D. The 42000m3/h air separation plant is a supporting project for the 300,000-ton/year methanol plant in Tengzhou Phoenix. According to the contract, delivery must be completed within 17 months. The air separation will adopt advanced technological processes such as column packing on structured packing, hydrogen-free argon, and internal compression of oxygen. The designed values ​​of oxygen, nitrogen, and argon are 42800m3/h, 21200m3/h, and 1370m3/h, respectively.
It is understood that the demand for air separation equipment in the domestic coal chemical market has accounted for more than 30% of the total market demand, and most of the required equipment is 30,000, 40,000 or more large-scale equipment.
