On December 22, 2013, good news came from Ningxia that the KDN-2200 high purity nitrogen air separation plant designed, manufactured, installed and debugged by our company was successfully started in Xiangmei Chemical Co., Ltd. Since all the indexes reached the design requirements in December 19, and after the operation in recent days, all the technical indexes have reached or exceeded the design standard, and they have been sending nitrogen for several consecutive days, which has been well received by users. Technical indicators are as follows:
High purity nitrogen purity: 99.9999% N2 (oxygen content ≤1ppmo2 );
This equipment is our company's first set of matching nitrogen separation equipment with the project of annual output of 50,000 tons of lime nitrogen. It is also the first set of equipment with double towers and double condensation technology. It is our company's first set of nitrogen equipment in this area. The successful start-up of this set of nitrogen-making equipment reflects the advancement and superiority of our company in the process of high-purity nitrogen equipment, and also opens up a new market for our company in northwest area.
