On September 18th, the good news was that Kaifeng DEAR Air Separation Industrial Co., Ltd. (hereinafter referred to as DEAR Air Separation) successfully started the KDONAr-8000/8000/180 type air separation equipment for the thin plate project signed by Panhua Group Co., Ltd. (hereinafter referred to as Panhua Group), with stable operation and oxygen and nitrogen indicators meeting or exceeding the contract indicators, providing strong support for the subsequent production of the entire project.
Panhua Group is one of the top 500 private enterprises in China, with businesses covering various fields such as thin plate, mining, real estate, logistics, etc. Its main thin plate industry is a large color steel production base for private enterprises in China.
This device adopts a new * * packing tower structure and a new self boosting process, effectively increasing the oxygen outlet pressure of the product, reducing the exhaust pressure of the air compressor, and increasing the inlet pressure of the oxygen compressor, thereby greatly saving energy consumption of the device. In order to ensure the successful start-up of the air separation unit and the smooth production of qualified products, the DEAR Air Separation Panhua Project Department prepared for production, technology, and personnel in advance, and completed the preliminary work of linkage debugging, pipeline blowing, cold box bare cold leak detection, and pearl sand filling for the 1 # and 2 # compressor units. The technical personnel of DEAR Air Separation actively communicated with personnel from Panhua Company and supporting equipment manufacturers multiple times, developed a safe and reliable overall testing plan, steadily promoted the testing process, and successfully started the final air separation device in one operation, successfully producing qualified products. The overall performance of this equipment is excellent and has received high praise from users.
