GT-LNG — Better Solutions
Next-generation LNG plants will be designed to achieve an annual output of 6
to 8 million tons or more, requiring upwards of 240 MW of total compressor
power for the refrigeration process alone. As a result, compressors and
their respective drivers will be considerably largerscale compared to
today’s installed base. Tomorrow’s plants, however, won’t just be built
around larger machines, but better solutions.
Siemens has introduced its renowned SGT6-2000E (ex V84.2, 110 MW (ISO) at
3,600 rpm) and SGT5-2000E (ex V94.2, 160 MW (ISO) at 3,000 rpm) as LNG
mechanical drive gas turbines. These units not only exceed currently
available products in their respective class by approximately 20% in power
rating. They are also optimized for maximum periods between inspections and
shortest maintenance downtimes, requiring just four days of maintenance
after 16,000 equivalent operating hours (EOH) and 16 days after 48,000 EOH.
This is, in part, due to the silo combustors at each side of the gas turbine
casing, which can be accessed by a normal-sized person for inside inspection.
What’s more, the SGT6-2000E and SGT5-2000E can handle both low calorific
fuel gas and gas with a high content of nitrogen.
With a track record of more than 220 installations, these gas turbines have
proven their credibility in generator drive applications around the world —
applications which are typically more demanding than continuous-load LNG
operation.
For small-size refrigeration trains, Siemens offers the well-proven SGT-600
and SGT-700 mechanical drives, rated ISO 25.5 MW and 30 MW respectively. |
