Development of each phase in South Pars Gas Field adds to the gross domestic product by 1%, managing director of the huge gas complex said.
"The share of fossil fuels in Iran's energy basket is 74%, of which 50% is produced by SPGC," Hadi Hashemzadeh Farhang was quoted as saying by ILNA on Tuesday.
South Pars, the world's largest gas field and shared between Iran and Qatar, is being developed in 24 phases. Nineteen phases are up and running and phases 13 and 22-24 are nearing the final stages.
Phase 11 has not developed yet.
After the French energy company Total and China National Petroleum Corporation cancelled their agreement to develop Phase 11, the National Iranian Oil Company has not announced any new plans to develop the phase
Hashemzadeh said South Pars accounts for 96% of liquefied petroleum gas, 100% of ethane and 55% of sulfur produced in Iran.
Data pertaining to 2018 show a rise in the output of several byproducts, namely ethane (42%), gas condensates (5%), LPG (35%) and sulfur (35%), compared to 2017.
SPGC also accounts for 67% and 92% of the total natural gas and gas condensate output respectively.
Close to 650,000 barrels of gas condensate per day is supplied to the Persian Gulf Star Refinery in Hormozgan Province and Nouri Petrochemical Complex in southern Bushehr Province as feedstock.
"Three gas refineries of South Pars Gas Field in Bushehr Province will come on stream by March," he said, adding that 13 natural gas processing units are also being developed of which 10 have been completed and the remaining three are in the final stages.
Refineries of phases 20-21, 17-18 and 19 were launched between 2017-18.
Domestic manufacturers provide almost 90% of equipment for the major complex, including electrical and mechanical infrastructure needed for refinery overhaul and for producing chemicals like industrial oils and catalysts.
The field, which straddles between Iran and Qatar, holds an estimated 39 trillion cubic meters of natural gas in place, of which 14 tcm is in Iranian territory and the rest in the tiny Arab emirate off the Persian Gulf.
Iran's GDP reached $33.38 billion during the first half of the current fiscal (March 21-Sept. 22, 2018), the Statistical Center of Iran reported.
