China's independent refiners have increased their intake of Iranian crude oil after Beijing issued a new round of import quotas late last month.

Mobin Energy Persian Gulf Company, as one of the largest centralized utility units in the world, with an area of ​​over 88 hectares in Phase One of the South Pars Special Economic Zone in Assaluyeh, plays a key role in providing energy and infrastructure services for petrochemical complexes.

Tabriz Oil Refinery, one of the most important refining centers in Iran, plays a key role in supplying the liquid fuel needed by northwest Iran by providing about 7 percent of the country's crude oil refining capacity.

Parsian Oil and Gas Petrochemical Holding is one of the major players in the country's petrochemical industry, which, with about 20 percent of Iran's production capacity and complexes such as Pardis and Zagros, has earned the title of the country's largest urea producer and one of the most important methanol producers in the Middle East.

Hossein Mirafazli, an energy expert, says: If only 10 percent of intracity trips are shared, about two million liters of gasoline will be saved daily, which is equivalent to more than $700 million in annual savings for the Iranian economy.

Petrofarhang Holding, the economic arm of the Farhangian Reserve Fund, has been able to consolidate its position as one of the main players in Iran's petrochemical industry in recent years, focusing on methanol production and developing petrochemical projects, and has emerged from losses with significant growth in production and profitability.

Energy expert Hossein Mirafazli believes that the way out of the gas consumption crisis is to reduce dependence on gas and expand the use of electricity in home heating; a model that many developed countries in the world have adopted for years.

The Persian Gulf Star Refinery, Iran's largest gasoline producer and the world's largest gas condensate refinery, plays an unparalleled role in Iran's energy supply by producing more than 45 percent of the country's fuel portfolio.

As a new wave of sanctions from the United States, Britain and the European Union target sales of Russian and Iranian oil, trade sources told Reuters that discounts on Iranian oil for Chinese customers have reached their widest in more than a year, reaching as much as $10. Reduced oil import quotas for independent Chinese refiners have also added to the pressure.

This resignation is related to a project called Hirsa Polymer Sahand Petrochemical, which has serious uncertainties about how it will be handed over to a second-hand contractor.
