GE Gas Turbine to Power One of World’s Largest PTA Production Plants

Posted on May 28, 2009

GE Energy’s Frame 6B gas turbine technology has been selected for a cogeneration plant being built as part of a new project in the Sines petrochemical industrial park that will contribute to the regional development of Portugal’s Alentejo coastal area and to the revitalization of the Sines port.

When completed, the 40 MW facility will support a pure tereftalic acid (PTA) producing plant that will have a PTA production capacity up to 700 000 tons per year, making it one of the largest production plants of its type in the world. PTA is the raw material required for the production of polyethylene terephtalate (PET), a polymer resin widely used in synthetic fibers, packaging applications and engineering resins. The PTA plant, to be named Artenius Sines, will be owned and operated by La Seda de Barcelona, a chemical company and a leader in the PET packaging sector.

The new GE Frame 6B gas turbine has been delivered to the Sines site, which is south of Lisbon, with commercial operation scheduled for early next year. Plans are to use natural gas as the primary fuel source and limit NOx emissions to 15 parts per million (at 15% O2).
