Iran Gas Trunkline
Iran Gas Trunkline (IGAT) is the series of large diameter pipelines constructed from gas producing areas in the south of Iran (Kuzestan and Bushehr Provinces) in order to transfer natural gas to the consumption centres in northern part of the country.[1]
As of 2008, there are five trunkline in operation, two under construction and two under planning.[2]
History
IGAT1 was completed in October 1970, supplying the Southern Caucasus republics of the Soviet Union. In 1975 the National Iranian Gas Company concluded agreements with Ruhrgas, Gaz de France, the Soviet Union, and Austria's OMV, to supply gas to Western Europe via a proposed IGAT II. Under the arrangement, Iran was to supply additional gas to the Soviet Union, while the Soviet Union was to pipe gas to Czechoslovakia from its own gas fields in Siberia. Construction of IGAT II halted following the Iranian Revolution.[3]
Main transmission lines
- IGAT1, 42 inches (1,070 mm) in diameter, was constructed between Bid Boland Refinery in Khūzestān Province and Astara in North.
- IGAT2, 56 inches (1,420 mm) in diameter, was constructed between Kangan Refinery in Fars Province and Qazvin in north.
- IGAT3, 56 inches (1,420 mm) in diameter, was constructed between Asalouyeh and Central Province and ultimately to north west of the country.
- IGAT4, 56 inches (1,420 mm) in diameter, transfers natural gas produced in South Pars phases 1 to 5 from Asalouyeh to Fars and Isfahan provinces.
- IGAT5, 56 inches (1,420 mm) in diameter, transfers sour gas produced in phases 6, 7 and 8 to Khūzestān Province to be injected into the oil wells.
- IGAT6, 56 inches (1,420 mm) in diameter, transfers natural gas produced in South Pars phases 6 to 10 from Asalouyeh to Khūzestān Province to be consumed there and in the west of the country and in Iraq.[4] See also: Iran-Iraq-Syria pipeline
- IGAT7, 56 inches (1,420 mm) in diameter, interconnects east of Asalouyeh to Hormozgān Province and Sar-Khoon Refinery and transfers natural gas produced in South Pars to Hormozgān, Sistan, Baluchestan and Kermān provinces.
- IGAT8, 56 inches (1,420 mm) in diameter, originates in east of Asalouyeh and passes by Parsian Refinery in Fars Province onto Isfahan Province and then to Qom Province.
- IGAT9 (Europe Gas Export Line), 56 inches (1,420 mm) in diameter, originates in east of Asalouyeh and passes by western provinces (Khūzestān, Īlām, Kurdistan and Azerbaijan) and reaches to Turkey's border.
