Speaking to Shana, he underlined that refineries should undergo full set of repairs and this is key to realization of targeted goals in petrochemical sector.

The official said that NIOPDC will pursue production of qualified products based on Euro 4 standards in the petrochemical sector.

Abbas Kazemi, managing director of NIOPDC has also said before that Iran's refining capacity can reach 3.1 mbd once several refinery projects become operational across the country in the years to come.

The refineries will process crude oil, gas and condensates, he said.

"Promoting optimum use of energy, avoiding sales of crude oil and gas, strengthening the economy against foreign assaults such as sanctions, and bolstering national self-esteem and confidence are among the policies that NIOPDC is seeking to realize," the official said.
