“Registered company”Hella Face Arena“Knowledge-Based Names Iran along with five other industrialized countries as a country that possesses the technical know-how of this equipment thanks to the localization of this Approved technology 100%.

Soheili Pour, Vice Chairman of the Board of Directors and Director of Market Development at this Iranian knowledge company, explained the details of this remarkable Iranian achievement.

According to him, this manufactured equipment is classified into a category Heat exchangers Low temperature and high pressure, it has vital applications in key industries such as petrochemicals, oil refineries and steel and copper complexes.

He also noted that this equipment was specifically included in a sanctions list US andEuropean Union Since 2009 due to its strategic importance, he said:

“By focusing on interior design, we were able to equip the plant in 2010, and finally deliver the first fully Iranian model to the South Pars Gas Complex in 2021.”

The market development manager of this knowledge-based company stated:

“The importance of this achievement becomes clear when we know that the monopoly on manufacturing these transformers was previously reserved for a few companies from Japan, Europe, US And China. Now, this Iranian product, which is considered “Core processing units“In plants such as methanol, oxygen, Liquefied natural gas And olivine (olivine), not only became operational in the country, but also opened the doors for export.”

Soheilipor announced an export contract with the Venezuelan company PDV Gas, and said:

“Building five boxes per unit Liquefied natural gas “This country is in its final stages and will be exported soon.”

Soheilipour pointed out in his reference to: Providing job opportunities than 200 young people specialize in this complex, and he stated:

“We are currently the only local manufacturer of this product, but we welcome other companies to enter this field to completely eliminate dependence on imports.”

The strategic importance of the project

Since cold box cryogenic exchangers are the heart of processing units in petrochemical and gas refineries, gas processing and injection into gas supply lines for industries and urban gas depend on the existence and stable performance of these exchangers.

In fact, along with important rotating equipment such as turbine compressors, cold boxes are the backbone of the country’s sustainable gas supply.

In addition, they play an essential role as equipment in separating air gases and supplying oxygen to the petrochemical, steel, and copper industries, as well as preventing the combustion of flammable gases.
