Enagas selects GE technology for new gas pipeline station in northern Spain

GE’s Oil & Gas business will supply two gas turbine-driven turbocompressor units to Enagas, the operator of Spain’s gas transportation system, for a new pipeline compression station at Navarra in northern Spain.

The new station will help to increase the flow of the Lacq-Calahorra pipeline and its interconnection with the Ebro axis. The pipeline, which carries natural gas from France to Spain, crosses the French border near the Spanish village of Larrau.

Each of the two GE turbocompressor packages will include a PGT 20 gas turbine with a dry low emission system and a BCL604/N compressor. GE also is responsible for erection, commissioning and spare parts. 

The LM2000 gas generators for the turbocompression packages will be manufactured at GE’s facilities in Cincinnati in the United States, while the remainder of the equipment for the project will be supplied from our facilities in Florence, Italy. Commercial operation of the new station is expected to begin by the end of 2007.

Enagas, based in Madrid, will own and operate the new compression station, while Tecnicas Reunidas Group/Initec Plantas Industriales is the engineering company for the project.

GE Oil & Gas previously has supplied turbocompressor packages to Enagas for two other pipeline stations, in Cordoba and Banyeres. Enagas owns gas pipeline and transportation networks, regasification plants and gas storage facilities across Spain.                

GE technology will boost the Trans-Tunisian pipeline expansion

We are also providing new turbocompressor units and an upgrade of existing equipment to increase the pumping capacity and extend the operating life of the Trans-Tunisian pipeline, which transports gas from Algeria through Tunisia to Sicily, Italy.

Société de Construction Gazoduc Transtunisien (SCOGAT), owned 100 percent by Eni, is in charge of the project, while Snamprogetti of Italy will handle the entire contract as an EPC contractor.

During the feasibility phase, a working group was created to examine all possible scenarios and select the most appropriate solution both from a technical and an economical standpoint.

Under this contract, eight new turbocompressor trains will be supplied and installed, including:

• one train (BCL404/A Centrifugal compressor driven by MS5002C gas turbine) in the Cap Bon compression station,
• one train (PCL603-2 Centrifugal compressor driven by PGT25 gas turbine) in the Feriana compression station,
• six turbocompressor trains (PCL801 Centrifugal compressors driven by PGT25 gas turbines) in the newly-designed Sbeitla and Korba compression stations.

Also, at the Cap Bon station, five MS5002B gas turbines will be replaced with five MS5002C while four MS5002B units will be upgraded to the MS5002C configuration.

The project will also include the upgrade or replacement of several auxiliaries such as heat exchangers, gearboxes, couplings, instrumentation and control panels as well as the retrofitting of five high-pressure barrel compressors with dry gas seals.

All equipment for this project will be supplied from GE’s facilities in Florence, Italy. The project is slated for completion in two phases. The first will allow the customer to increase gas transportation by upgrading the existing compression stations. The second will bring the new compression stations into operation.
