Large complete air separation plant KDON(Ar)- 30000/70000-900 solution for chemical industry

Large complete air separation plant KDON(Ar)- 30000/70000-900 solution for chemical industry
Project Background

DEAR air separation has provided many sets of air separation plant for chemical industry for many years, with rich experience and the safe and stable unit operation. This 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. The rapid growth of enterprises in the industry is accompanied by the demand for production and the demand for air separation plant. DEAR air separation has cooperated with customers in the large-scale complete set of air separation plant KDON (AR) - 36000/70000-1200 project, which provides customers air separation plant with mature technology, reliable and convenient operation, and energy saving intelligence, which improves the production efficiency of customers, saving the operation cost and creates greater economic benefits.

Scheme Introduction

Solution advantages

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
