The fourth national gas pipeline’s capacity is increased by 100 million cubic meters per day (mcm/d), said Ali Akbar Meraati, manager of compressor stations at the National Iranian Gas Company (NIGC), Shana news agency reported. Having gone into operation last week with a total investment of 52 million euros and $9.4 million, Dahagh compressor station has expanded capacity of the fourth pipeline of Iran’s National Gas Trunkline (IGAT).
Each turbo compressor at the station has a capacity of 25 megawatts, and capable of transferring 35 mcm/d of gas. The outlet pressure of the turbo compressors stands at 1,350 psi. Most of the compressor station’s equipment utilized in north of Isfahan Province was manufactured domestically, Meraati noted, adding that the entire design, implementation, and supervisory operations were carried out by domestic experts.
Stretching for 1,145 kilometers, IGAT4 passes through Parsian, Neizar, and the city of Saveh in Markazi Province. A total of 10 compressor stations boost the pipeline’s gas pressure along the way. The 56-inch (1,420 mm) pipeline, with a capacity of 110 mcm/d, transfers natural gas produced in South Pars phases 1 to 5 in Assalouyeh to Fars and Isfahan provinces.
A total of six compressor stations are scheduled to start operation in the current Iranian calendar year (ending March 20), the most important of which is the Kheirgou compressor station on IGAT4, Meraati said in January.
