Siemens and its Dresser-Rand business will supply two gas turbine-driven compressor trains and two gas turbine generator packages for the Liwa Plastics Industries Complex, a petrochemical project in Oman. The natural gas liquids (NGL) extraction plant in Fahud, situated approximately 158 mi. (300 km) southwest of the capital of Muscat, is part of the industrial complex. The order was placed by the South Korean construction firm GS Engineering & Construction Corporation for the state-run oil refinery and petrochemical provider Orpic, which will operate the plant and the industrial complex. The NGL extraction plant is expected to go into operation in 2019 to extract valuable liquefied natural gases.
The scope of supply includes four Siemens SGT-700 industrial gas turbines. Two of the gas turbines each drive a barrel-type turbocompressor (STC-SV) for lean gas compression. The lean gas will be routed back to the national natural gas distribution system. The other two gas turbines, each of which drives a generator, will supply electricity to the Fahud NGL plant to extract natural gas liquids and provide waste heat for the NGL extraction process. The extracted NGL from rich gas feed will be transported via a pipeline from Fahud to Sohar. NGL is the feedstock for the petrochemical complex in Sohar. The Liwa Plastics Industries Complex will turn NGL into polyethylene and polypropylene plastics, which are used for products like packaging, suitcases, garden furniture, cars, and computers.
