Case of DEAR air separation and Hongxing Iron and Steel Company
Qinhuangdao Hongxing Iron and Steel Co., Ltd.
Qinhuangdao Hongxing Iron and Steel Co., Ltd. (hereinafter referred to as Hongxing Steel) was established in 2002. The company is located in Changli Circular Economy Industrial Park, Qinhuangdao City, Hebei Province, with a registered capital of 3.3 billion yuan and more than 5000 registered employees. After more than 10 years of development, it has become a large scale private iron and steel joint enterprise integrating oxygen production, sintering, iron making, steel making and steel rolling, and ranks among the top 100 enterprises in Hebei Province and the top 500 enterprises in Chinese manufacturing industry.
Flow:
Purity: ≥99.6%
Industry: Large air separation case
Project address: HeBei,China
Project Overview

DEAR air separation signed the KDON-16000/35000 air separation plant contract with Hongxing Iron and Steel Co., Ltd. The set of air separation plant was successfully started at first time, all indexes exceeded the design indexes, and the working condition was stable, and getting the unanimous approval of the Hongxing Steel Company.

Product Advantage

The unit adopts molecular sieve purification, booster turbine expander to supply the cooling capacity of the unit. When the gas volume of expander is large, the liquid oxygen output can be increased when the oxygen is not used much, which is safe, reliable and economical. The main reasons are as follows:

 

1.Good safety

The whole set of device has the advantages of low operating pressure, simple process, high equipment safety, long switching cycle of molecular sieve system, increased service life of switching valve, and reduced potential hazards.

A large amount of liquid oxygen is extracted from the main cooling (K1) to minimize the possibility of hydrocarbon accumulation.

 

2.High reliability

A large amount of surplus nitrogen can be sent to the water cooling tower, reducing the load of the water chiller, reducing the energy consumption and cost of air separation, so that the reliability of the device is further improved.

 

3.Convenient operation and maintenanceandsimple process
