Technological features

Î APCI AP-X Liquefaction Processes

Î A complex train design with

z High energy efficiency – heat recovery on GT exhausts z C3+ NGL recovery (Ortloff Score process)

z Gas phase removal of mercaptan sulphur

z Large electrical motors for power transfer and pressurized refrigerant compressor start up

Î GE Frame 9 Gas turbine drivers

Î Abnormally large utilities and offsites

z Cooling water z Flare

• 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 (45o_{C to -30}o_C)

–Mixed hydrocarbons (-30o_{C to}

-114o_C)

–Gaseous nitrogen (-114o_{C to}

-160o_C)

• 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

APCI AP-X Process: Spoolwound exchangers

Helically wound 10mm tubes All aluminium construction

Low technological risk despite new configuration

Two exchangers in series for LNG condensation (against MCR) and subcooling (against N2)
