Case of DEAR air separation and Fujian Sanjin Iron and Steel Company
Fujian Sanjin Iron and Steel Co., Ltd.
Fujian Sanjin Iron and Steel Co., Ltd. is located in Luoyuanwan Economic and Technological Development Zone of Fuzhou City, which is known as the place for investment. It covers an area of more than 1600 mu. It is near Tongsan expressway, Wenfu Railway, Luoyuan 30000 ton wharf and No.104 national highway. It is only 60 kilometers away from Fuzhou Changle International Airport, with convenient transportation and obvious location advantages. With a registered capital of 500 million yuan, the company plans to invest 1.5 billion yuan in two phases to build a modern iron and steel enterprise with an annual output of 1.2 million tons of steel by 2012.
Flow:
Purity: ≥99.6%
Industry: Small air separation case
Project address: FuJian,China
Project Overview

DEAR air separation signed a contract with Fujian Sanjin Iron and Steel Co., Ltd. for KDON (Ar) - 6500 / 6500-180 air separation plant. The process characteristics of the project: multistage distillation, hydrogen free argon production. Since operation, the equipment has stable working conditions and excellent performance.

Product Advantage

The unit adopts molecular sieve purification, booster turbine expander to supply the cooling capacity of the unit, and the whole rectification hydrogen-free argon production process, 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.

 

  1. 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.

 

  1. Convenient operation and maintenanceandsimple process
