TODAYS DESIGN 4 to 5 Mt/a
NATURAL GAS
LNG

• One main heat exchanger
• Two Frame 7 gas turbines
• One Propane compressor
• One mixed refrigerant cycle
• Split compressor arrangement

4
CRITICAL PIECES OF EQUIPMENT

• GAS TURBINES
• PROPANE COMPRESSOR
• MAIN EXCHANGER

5
GAS TURBINES

• USE LARGER ELECTRIC MOTOR HELPERS
• USE LARGER GAS TURBINES FRAME 9
• USE A THIRD FRAME 7

6
PROPANE COMPRESSOR

• USE A MIXED REFRIGERANT APCI DMR or LIQUEFIN
• REDUCE THE PROPANE FLOW PER UNIT OF LNG AP-X or
  TECHNIP MLP
• REDUCE COMPRESSOR ROTATING SPEED
• INSTALL TWO 50 COMPRESSORS IN PARALLEL

7
PROPANE COMPRESSOR

• MODIFY COMPRESSION STAGES ARRANGEMENT

• SEPARATE NATURAL GAS and MIXED REFRIGERANT
  PRE-COOLING DUTIES 30 MORE LNG

8
MAIN HEAT EXCHANGER

• APCI PROPANE PRE-COOLED DUAL STRING (3 CYCLES)
• AP-X 3rd CYCLE (NITROGEN)
• TECHNIP MLP  3rd CYCLE  ON SLIP STREAM
• AXENS LIQUEFIN ADD COLD BOXES IN PARALLEL (3
  CYCLES)

COMPARISON
AP-X
DUAL STRING

• WELL KNOWN PROVEN

• NEW COMPLEX

• 3 DIFFERENT CYCLES

• 3 CYCLES (2 IDENTICAL)

• 5 or 6 COMPRESSORS (5 or 6 MODELS)

• 6 COMPRESSORS (3 or 4 MODELS)

• COLD BOXES TURBO-EXPANDERS

• NONE

• REDUCED AVAILABILITY 10 LOST DAYS per YEAR

• BETTER AVAILABILITY

• ALL PROVEN EQUIPMENT

SCALE EFFECT

• 50 CAPACITY INCREASE (7.5 vs 5.0 Mt/a)
• REFERENCE 0.65 POWER FACTOR ? COST x 1.30
• PROCESS TRAIN COST x 1.35
• PROCESS DIRECT RELATED UTILITIES COST x 1.30
• SIMILAR EFFECT FOR APCI OR AXENS

8.7 Mt/a TRAIN

• an 8.7 Mt/a LEAN LNG
• 1.3 Mt/a LPG ETHANE
