Case of DEAR air separation and Myanmar Iron and Steel Company

Case of DEAR air separation and Myanmar Iron and Steel Company
Myanmar Iron and Steel Company is a famous steel company in Myanmar. Its main industries include sintering, coking, iron making, steel making, oxygen producing, hot rolling plate, bar, wire rod and profile production line.
Flow:
Purity: ≥99.6%
Industry: Small air separation case
Project address: Myanmar
Project Overview

DEAR air separation and Myanmar Iron and Steel Company cooperated on the contract of KDON (Ar) - 1500 + 40Y / 1500 / 40Y air separation plant. This set of equipment is  1500N m³/h type with argon air separation plant exported to Myanmar. The signing of the project marks the full trust and affirmation of users on the argon production technology of DEAR air separation. DEAR air separation always keeps technology leading and quality-oriented principle. With unremitting efforts and exploration, DEAR’s technology of argon production has reached the advanced level in the industry.

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
