MECI/Somague consortium selected for project in excess of 65 million euros.
The contract for a new SPCG combined cycle power plant to be installed at Portucel’s manufacturing complex in Setúbal has been awarded to a consortium led by MECI. This project is crucial to the increase in paper production capacity associated with the coming on stream of the Portucel Soporcel Group’s new paper mill located at that manufacturing complex.
The new cogeneration power plant, to be constructed inside the perimeter of the manufacturing complex situated on the Mitrena peninsula in Setúbal, is intended to supply steam to the new paper mill belonging to About the Future - Empresa Produtora de Papel S.A., a company of the Portucel Soporcel Group. The power plant will consist of two gas turbines, two recovery boilers and a steam turbine.
The General Electric aeroderived gas turbines will have a unit power output of approximately 30 MWe at the alternator terminals. The recovery boilers use the exhaust gases from the gas turbines and also have an additional burner system. The steam turbine will have a power output of approximately 17 MWe at the alternator terminals and the extraction and exhaust steam will be used in the new paper mill.
The gas turbines will be encased to protect them from the weather and to ensure acceptable noise levels. To minimise the formation of nitrogen oxides (NOx) the burners in the combustion system will be of the low emission type.
The design and construction contract will be managed by SPCG - Sociedade Portuguesa de Co-Geração Eléctrica, SA, a wholly owned subsidiary of Portucel Soporcel. The contract price is over 65 million euros and the power plant is expected to come on stream in July 2009.
summary specification
> 2 gas turbogenerators and one steam turbogenerator. The generators will produce an electrical power output of approximately 82 MWe at the alternator terminals, of which 43 MWe will be for the new papermaking machine, with the balance being sold to the public electricity grid. The interconnection will be effected at the Praias do Sado substation at 60 kV.
> 2 recovery boilers recovering the energy contained in the turbines’ exhaust gases will have a maximum steam production capacity in continuous operation of 140 Ton/h of superheated steam at a temperature of 510ºC and a pressure of 82 bar, and 10 Ton/h of steam at low pressure. All the steam generated is intended for the new papermaking machine. |
