Hassan Shamshiri said a delegation from the company is to visit Iran to explore a joint venture with an Iranian gas refinery.

He said the refinery also used to collaborate with Siemens in designing and equipping its units but had to postpone cooperation due to sanctions.

With the removal of sanctions, he added, these two companies are planning to return to the country.

He also said the refinery is going to work with a Russian company which is an expert in construction of gas sweetening units using latest technologies.

The official made the remarks when accompanying reporters in a visit to Jam Gas Refinery which is located in the Persian Gulf province of Bushehr.

Its eight units have the capacity of processing 125 million cubic meters of gas per day.
