Improving efficiency and cutting emissions with gas turbine technologies
Operating companies are turning to advanced gas turbine technologies to boost efficiency and meet emissions regulations. Sean Ottewell reports.
Las compañías operadoras están pasándose a tecnologías de turbinas de gas avanzadas para aumentar el rendimiento y cumplir con las normativas relativas a emisiones. Informa Sean Ottewell.
Betreibergesellschaften wenden sich fortschrittlicher Gasturbinentechnik zu, um ihre Effizienz zu steigern und Emissionsvorschriften einzuhalten. Ein Bericht von Sean Ottewell.

E is shipping two Frame 6B gas turbines for one of the largest cogeneration facilities in Portugal, Galp Energia’s Matosinhos
cogeneration plant near Porto. Replacing older oil-fired technology at the site, the gas turbines will increase the plant’s efficiency and reduce its environmental impact in line with the Portuguese government’s regulation to promote efficiency and reduce carbon dioxide emissions (Fig.1). Approved in January 2010 and in support of the European Union cogeneration directive, a new Portuguese law will regulate cogeneration on a national level. Te Frame 6B gas turbines are expected to provide all of the steam requirements for the nearby Galp Energia’s Matosinhos refinery and also will enable Galp Energia to produce electricity and sell it to Portugal’s national grid. Te Matosinhos cogeneration turnkey project is being developed for Galp Energia by the consortium Ensulmeci-Efacec
Cogeraçao do Porto, ACE, formed by two of the major Portuguese engineering, procurement and construction companies. “Te modernisation of our refineries with GE Frame 6B gas turbines supports the growing interest in Portugal to implement cogeneration as a more efficient, cleaner way to produce electricity and meet our process steam needs,” said Ricardo Manzoni of Galp Energia. “Te use of 6B technology at the Matosinhos plant will enable us to avoid emissions of over 400 000 tons of carbon dioxide per year.”
Te new gas turbines are the third
and fourth GE 6B gas turbines selected by Galp Energia to modernise power and steam production for its refineries in Portugal. Te first two 6B machines recently entered commercial operation at a cogeneration plant that supports the Sines petrochemical industrial park. Both the Sines and Matosinhos cogeneration plants have power capacities of 80 megawatts. GE‘s scope of supply for the
Matosinhos project also includes gas turbine auxiliary equipment, technical advisory and training services, during construction and commissioning. A contractual service agreement also has been signed, providing for ongoing maintenance of the GE gas turbines. Dresser-Rand has also been with,
recently announcing that it will supply advanced turbomachinery to three different clients for four floating, production, storage and offloading (FPSO) vessels, three of which are destined for Petrobras’ pre-salt oil fields in the Santos Basin offshore Brazil and one for the UK sector of the North Sea. Te company will supply 14 centrifugal
compressor trains comprising eighteen casings, two DR-61G (LM2500) mechanical drive gas turbines and four DR-61GP (LM2500+) gas turbine generator sets for these projects. Te total
