• New refrigeration process required for larger train capacities

–Extension of Existing Technology

–Combines LNG and Air Separation Technologies

–Uses Two Spiral Wound Heat Exchangers (SWHE)

• Three refrigeration services–Propane (45oC to -30oC)–Mixed hydrocarbons (-30oC to -

114oC)–Gaseous nitrogen (-114oC to -

160oC)• New process + large capacity =

large refrigeration requirement–275 MW of power required for

7.8 MTPA of lean LNG + .85 MTPA of LPG

–Current technologies require 150 MW for 4.7 MTPA Train of rich LNG

Frame 9E • Scale-up of Frame 7• 130 MW ISO• 210,000 kg package• 50,000 kg rotor• 350 Power Generation service

since 1979• 4 in Steel Mill service since

1998

Customized for LNG Service• Speed range 96%-102%• Continuous duty, base load• Extended maintenance

intervals with ExtendorKitTM

• Meets Qatar environmental requirements using DLN1

Frame 9E Incentives• High Power - 100 MW site rating (49oC day)• 3000 RPM - better compressor speed match• Flat LNG production

Motor/Generator• 45MW• 60MW during peak• C3 & N2 send power to MR
