LNG Mini, Small and Medium scale APC-U OIL & GAS, BOLOGNA, 26/9/2016
Slide 2: Small scale LNG
G r_ engineering for a a better world [ oy | Small scale LNG
Slide 3: GEA scope: LNG scale defining
LNG scale defining Mini scale plant >0,004 MTPA (up to 4000 t/Y) Small scale plant >0,01 MTPA GEA scope (up to 10 000 t/Y) Medium scale plant 0,3 -1,5 MTPA (from 300 000 up to 1 500 000 t/Y) Large base load plant 4 MTPA (8MTPA single train active in QATAR)
Slide 4: Why small scale LNG?
Why small scale LNG? There is a global increasing need for diversification of energy suppliers due to politics, economics and reserves; LNG supply chain is much more flexible than gas pipelines, being able to serve different markets at different times and able to avoid the political and geopolitic
Slide 5: Small-scale LNG plants applications
Small-scale LNG plants applications Peak shaving plants Satellite LNG plants for gas transport where pipeline is nonexistent On-board ship liquefaction Coal bed methane recovery Bio-gas Landfill gas Shale gas liquefaction 24/10/2016 5
Slide 6: Features and benefits
Features and benefits Small to mid-scale liquefaction plants, up to 1 MTPA capacity, (around 10% of a base load liquefaction plant) focus upon standardizing compact, preassembled modular designs that can be deployed quickly with minimizing design and construction costs. Design Objectives: Process
Slide 7: Natural gas liquefaction processes
Natural gas liquefaction processes Natural gas liquefaction GEA solution for LNG processes Cascade Mixed Expansion liquefaction refrigerant based processes processes processes Single Without With Single Refrigerant Refrigerant component phase phase component mixtures mixture refrigerants separators
Slide 8: Cascade vs Mixed Refrigerant vs Expansion
Cascade vs Mixed Refrigerant vs Expansion Cascade Liquefaction Mixed Refrigerant Process Expansion Based Process 3 separate loops to approach the Cooling of NG with a blend of Use of turboexpander to generate cooling NG curve; refrigerants (Light HC and nitrogen); refrigeration; Each refrige
Slide 9: Mixed Refrigerant vs Cascade
Mixed Refrigerant vs Cascade Thermodinamically Mixed Refrigerant is more efficient; the heating curve comes closest to a reversible process because it minimizes the T differences between Methane the NG and the refrigerant; Cascade system requires smaller heat exchangers because the T differences
