HOUSTON, Sept. 26 -- A unit of Royal Dutch Shell PLC has let a contract to GE Oil & Gas for six 42-Mw gas turbines, equipped with dual fuel integrated gasification combined-cycle (IGCC) combustion systems, for the Pearl gas-to-liquids (GTL) project in Ras Laffan Industrial City, Qatar (OGJ Online, Aug. 7, 2006, Newsletter).
The contract scope includes IGCC combustion engineering, combustion system lab testing, spare parts, and training.
The gas turbines are capable of burning a range of low-btu fuel gasses, including a process off-gas derived from the core GTL reactors. The turbines will be installed in the 140,000 b/d Pearl GTL plant in a cogeneration configuration that will produce 180 Mw of electric power for use in the facility.
Natural gas is the backup fuel, and will be used for plant startup. Steam injection will be used to reduce nitrogen oxide emissions.
The first gas turbine unit will be required to meet power requirements during the commissioning of the GTL facility, scheduled to begin commercial operation by 2009-10. The six units are scheduled for shipment in late 2007 or early 2008.
