BAKU, Azerbaijan, October 8. Sulfur production at the 1st refinery of Iran’s South Pars Gas Complex (SPGC) has surged by 47 percent as a result of recent operational improvements, said Ali Ahmadi, Director of the refinery, in a statement to local media, Trend reports.
According to him, daily sulfur output at the refinery has now reached around 100 tons, driven by major overhauls and the replacement of catalyst beds. Ahmadi added that the increase in production has also helped reduce sulfur dioxide (SO₂) emissions in the area by 63 percent, playing an important role in environmental protection.
The official noted that the refinery’s technical team continues to take measures to minimize gas flaring.
"In the first half of the current Iranian year (from March 21 through September 22, 2025), the volume of flared gas released into the atmosphere decreased by 25 percent, and this downward trend is expected to continue until the end of the year (March 20, 2026),” he said.
The South Pars Gas Company's 1st Refinery processes the rich gas extracted from the first phase of the South Pars gas field. The refinery processes 25 million cubic meters of gas daily, which is then transferred to Iran's gas network through a 56-inch pipeline. In addition, 40,000 barrels of gas condensate are sent to storage for export, and 200 tons of sulfur are produced daily.
Meanwhile, the rich gas produced at the South Pars gas field is processed by the South Pars company. More than 75 percent of the gas consumed in the country is provided by this company. The company has 13 processing plants.
The South Pars gas field (called North Dome in Qatar) is a joint gas field of Iran and Qatar. The proven reserves of the South Pars Gas Field are estimated at 51 trillion cubic meters of gas, of which 36 trillion are extractable. Iran's share in the field is 14 trillion cubic meters of gas and 18 billion barrels of gas condensate.
