Case of DEAR air separation and Shandong Runjin Company
Shandong Runjin Heavy Industry Technology Co., Ltd.
Shandong Runjin Heavy Industry Technology Co., Ltd. was founded in 2012 with a registered capital of 50 million yuan. It is located in the west of Mingxiang street, Gangcheng Economic Development Zone, covering an area of 140 mu. It is a professional enterprise engaged in the research, development, production and sales of large castings and forgings. At present, the company is constructing "Heavy Equipment Supporting Large Casting and Forging Processing Project" and "High-end Precision Forging Casting and Forging integrated production Project", which is a key construction project in the city, with a total investment of 72664 million yuan. There are 50T electric arc furnace, 60T refining furnace, 60VD furnace, casting line and two forging lines. The annual production capacity of all kinds of large castings and forgings is 109900 tons. The products are mainly used in wind power, hydropower, machinery manufacturing and other industries, with an annual output value of 600 million yuan and

Project Overview

DEAR air separation and Shandong Runjin Heavy Industry Technology Co., Ltd. cooperated with KDON (Ar) - 4000 / 4000-110 air separation plant. Process characteristics of the project: multistage distillation, argon production without hydrogen.

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.

 

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
