GE gas turbine at Dutch fertiliser plant
Following successful factory testing of the prototype unit, the second GE MS5002E gas turbine exceeded performance guarantees during recent onsite tests and has entered commercial service
The unit is installed at a Yara Sluiskil BV fertiliser plant in Sluiskil, The Netherlands During a full-load test in premix mode (the normal combustor operating condition that enables lower emissions and less stress on component parts), the unit surpassed the contractually guaranteed electrical output by approximately one megawatt, with 3% less fuel consumption than specified in the contract

Production control system for subsea projects
VetcoGray has introduced a production control system product, the PCS1000, which offers an economical package, based on proven technology for fast-track, shallow water subsea projects
The gas turbine, equipped with latest GE Dry Low NOx technology (DLN2), also achieved 12 parts per million (ppm) of NOx emissions during testing, compared to the contractual guarantee of 18 ppm.
"In response to customer requirements, the Frame 5-2E has been designed for high efficiency and low environmental impact, and the initial performance of the machine at its commercial launch site has met or exceeded our expectations" said Alberto Tesei, Technology Commercialisation Leader of GE Oil and Gas.
"Compared to a standard 30-megawatt class gas turbine with 25 ppm NOx emissions, the Frame 5-2E is capable of reducing emissions by the amount that would be achieved in taking 5,000 European cars off the road".

Implementing its new PGT25+G4 power turbine technology, GE Oil and Gas has completed an upgrade project for Alliance Pipeline that will provide greater power output, high efficiency and low emissions
In addition to supplying the Frame 5-2E, GE Oil and Gas has signed a 15-year contractual service agreement with Yara Sluiskil that includes an availability guarantee.
The Frame 5-2E is the newest member of the GE Frame 5 gas turbine fleet, which has compiled more than 16 million hours of service worldwide.
The two-shaft machine combines the latest heavy duty gas turbine technology with proven design concepts to achieve 36% efficiency in mechanical drive operation and 35% in generator drive operation.
For its application, Yara Sluiskil needed a gas turbine capable of operating on two fuel compositions, G gas and H gas.
GE designed the Frame 5-2E to automatically adapt to any changes or blends in the gas composition, with no interruption in production.
The new Frame 5-2E, which began commercial operation on 5 November 2007, replaces an existing non-GE gas turbine at the Yara Sluiskil site.
It is producing 30+ megawatts of power and 50 tons per hour of steam to be converted into electricity elsewhere in the plant.
Prior to the installation of the second Frame 5-2E at the project site, the first unit produced underwent 600 hours of full-load validation testing at GE Oil and Gas facilities in Florence and Massa, Italy.
This heavily instrumented prototype unit performed as predicted, delivering power, efficiency, and emissions in line with engineering expectations.
