Siemens and its Dresser-Rand business have been contracted to deliver two gas turbine-driven compressor trains and two gas turbine generator packages for the Liwa Plastics Industries Complex, a petrochemical project located in Oman.
The natural gas liquids (NGL) extraction plant in Fahud is a part of this industrial complex.
Siemens received this contract from the South Korean construction firm GS Engineering & Construction Corporation, which placed the order on behalf of Orpic, Oman’s state-run oil refinery and petrochemical provider. The NGL extraction plant is expected to begin operations in 2019.
Under the contract, Siemens will supply four SGT-700 industrial gas turbines. Out of the four turbines, two turbines each drive a barrel-type turbocompressor (STC-SV) for lean gas compression. The lean gas will be transported back to the national natural gas distribution system.
The other two gas turbines each drive a generator and 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 will be transported via pipeline to Sohar from Fahud. NGL is the feedstock for the petrochemical complex in Sohar.
The Liwa Plastics Industries Complex will manufacture polyethylene and polypropylene plastics from NGL. These petrochemical products are used in packaging, suitcases, garden furniture, cars, and computers.
For the first time, Oman will be able to produce polyethylene. The same type of gas turbine will be used in the plant for generating boh electricity and lean gas compression. The SGT-700 gas turbine is especially suitable for these plants due to its fuel flexibility, compact dimensions, and high efficiency.
