It will be the aftermath of a project long desired by the refi nery and that will make a decisive contribution in the energy optimization of Galp Energia’s Industrial Complex as well as on reducing its environmental impact. Since the beginning this project has overlapped the conclusion of the Cogeneration Center of Sines (SINECOGERAÇÃO), which has the same kind of design, so it was possible to transpose into this second the experience of the fi rst. Indeed, and taking advantage of the sequence relationship in constructing both plants, Galp Power used the same team of engineers for the management and supervision of both projects with all the benefi ts it carries along. On the other hand, both Galp Energia Refi neries will use the same kind of technology in the simultaneous generation of electricity and steam which will create unquestionable operational synergies between both utilities factories. Thus Galp Energia will take a more a decisive step in the modernization of its refi ning apparatus making it more energy effi cient, better integrated with its environmental surroundings and more competitive to embrace in a more sustainable manner a new lifecycle starting in 2012. As happened in the previous cogeneration design for Sines refi nery, this new cogeneration center managed to obtain, from the European Investment Bank (EIB), a signifi cant increase of funding that is a mark of credibility to the project and a prize by the rigor with which Galp Energia promotes, manages and implements this kind of investments in its industrial core business. In addition to all benefi ts to the refi ning facilities, these new cogeneration power plants will create both value in Gas & Power, by adding new volumes of natural gas and by the use of gas in the effi cient generation of electricity which will be delivered to the public electricity network, that in the case of Matosinhos refi nery, is operated by EDP Distribution. The signifi cant steam consumption in the process of refi ning along its continuous operation regime, makes Matosinhos refi nery an excellence site for implementing the cogeneration technology and thus driven by the Utilities Factory team, this project gathers all the conditions to confi rm the good results already achieved in the Sines Cogeneration and also contribute to the success of this Galp Energia strategic industrial complex. MATOSINHOS REFINERY / DATA BOOK ON HEALTH, SAFETY AND ENVIRONMENT 2011 The design of the new Cogeneration Plant The new Cogeneration Plant consists of two gas turbines, industrial type of General Electric, model Frame 6B equipped with combustion chambers Dry Low NOx (DLN ENTERPRISES) with a nominal electrical power of unit 41 MWe. This model of gas turbine engines, industrial design (Heavy Duty), has more than 1000 references worldwide of which, several hundreds, are installed in the industry of Oil &Gas. Gás Turbine GE Frame 6B (DLN) Gas turbine technical data: • 17 stages bolted axial compressor; • equipped with Inlet Guide Vanes (IGV); • combustion chamber consisting of 10 annular elements; • NO x emissions: 15 ppm (15% O2) for natural gas; • turbine 3 stages of screwed connection. The two gas turbines are attached to two recovery boilers (Heat Recovery Steam Generators) that use the thermal energy contained in exhaust gases to produce steam for the refi nery. These boilers have natural gas post-combustion burners that using the exhaust gases as oxidizing, allow to modulate the steam unit production (@ 66 barg and 450ºC) since 85 ton/h (minimum) up to 130 ton/h (Maximum Continuous Rating), keeping unchanged the electricity production of the gas turbine that is attached to each boiler. Additionally the boilers are individually equipped with fresh-air systems which allow to maintain its operation in case of breaking down the Gas turbine. The boilers are manufactured by NEM that supplied in Portugal the combined-cycle recovery boilers of Tapada do Outeiro and Carregado.
01 02 03 3D model of the new cogeneration center Cogeneration center technical data: • 2 x GE Fr6B DLN + 2 x NEM HRSG (eq. c/ PC & FA); • nominal heat output: 82 MWe (2X41 MW e ); • steam generation capacity: 260 ton\h (@ 450 C, 66 barg); • electricity production: 670 GWh\year (forecast); • steam production: 1.6 megaton Tsar/year (forecast); • natural gas consumption: 232 Mm 3 (n)/year (forecast); • equivalent electrical effi ciency (REE): 75%. Under normal operation, the new Cogeneration Plant will produce the equivalent of about 70% of the electricity consumed in the municipality of Matosinhos with an equivalent (REE) electrical effi ciency of 75% (this value compares with the electrical effi ciency of a combined cycle power plant, which is currently 60%) which shows a primary energy savings exceeding 15%, and a reduction of CO 2 emissions at national level of 400,000 ton/year. Based upon these effi ciency values, the new power of the refi nery of Matosinhos is classifi ed, according to the Community Directive 2004/8/EC, as “high effi ciency” cogeneration. Interconnection of new combined heat and power plant with the external energy infrastructure The construction of New Combined Heat and Power meant new interconnections of the Industrial Plant to high pressure natural gas network and high voltage electricity distribution. ACTIVITIES, ACTIONS AND PROJECTS 05 06 07 08 09 10 11 The construction of the new pipeline and the GRMS (Gas Regulation and Metering Station) was of the responsibility of REN Gasodutos, having the electrical interconnection pipeline between the New Switch Station (built under the new combined Heat and Power Supply) and the Electrical Substation of Santa Cruz do Bispo powered by EDP distribution, been of the responsibility of PORTCOGERAÇÃO and the second section between this Substation and Substation of Custóias operated by REN, stayed been supported by EDP Distribution through previously established compensation agreements with PORTCOGERAÇÃO. Electrical interconnection between the Industrial Complex and REN Technical data of the Electrical Interconnection • fi rst section: two subway lines, the cutting, at 60kV from the Switch Station of Matosinhos refi nery to Santa Cruz do Bispo substation, extension: 3,751 m. • second section: two mixed lines, at 60kV, consisting fi rstly of underground line from Santa Cruz do Bispo substation to support no. 1, with an extension of 2,926 m, and an aerial part from support no 1. to support no. 4, with an extension of 648 m, and by a fi nal underground part, from support no. 4 to Custóias substation in a length of 112 m.
