Relying on domestic knowledge-based companies’ expertise, Iran’s Oil Ministry has managed to produce the high-tech component of cold box.

This piece of equipment is used in the ethane recycling unit of the South Pars Gas Complex (SPGC).

Cold box is among the most essential equipment of refineries and used for natural gas liquification, LNG cold utilization, ethylene production, methane production, air separation, boil-off gas (BOG) condensation, and CO-H2 separation.

The cold box made by French group Fives costs €3 million while the type designed and manufactured by Iranian knowledge-based company Hilavis Arina is around 20 percent cheaper and the homegrown model saves the country’s foreign currency by 11 percent.
