8LNG Liquefaction From natural gas to purified LNG at -163°C Two stage system: Pre-treatment (gas purification) Liquefaction (cooling to liquid state)Gas pre-treatment: Filtration and pressure reduction Sweetening (CO2 removal) Dehydration (H2O, glycol, Hg removal)Liquefaction based on N2 cycle
9LNG Onshore Liquefaction Hamworthy Gas Systems’ LNG plants at Snurrevarden and KollsnesSnurrevarden, Karmøy, start-up March 2003Kollsnes II, Øygarden, start-up July 2007First free-standing small scale LNG plant in Scandinavia. Capacity 60 ton LNG per day. Unmanned operation.Production capacity 240 ton LNG per day, supplying LNG to local ferries, coastal vessels and local industry (ferrosilicium/ aluminium).
10Floating Liquefaction Natural Gas FLNG Market potentialApproximately 25 % of the world’s gas reserves is ”unavailable” offshore fields (stranded gas) - FLNG makes it available!Estimated 10 billion ft3 gas flared worldwide every day - FLNG can make flaring history!Several analyses of projects under development show that FLNG costs compare favorable to land-based LNG production
11Floating Liquefaction Natural Gas FLNG Status for Hamworthy Gas Systems FLNGWhere do we stand in this new market?Several projects in bid phase, ongoing studiesRapidly increasing interest among investors, shipowners and energy companiesEstablished technology fit for FLNGUnique position within LPG/LNG liquefaction and processing systems – land-based, marine, and offshore!Modules for Floating Liquefaction of Natural Gas (FLNG) shown on section of LNG vessel.
12Patented - LNG plant, licenced by SINTEF Mini LNG plantsMarket potentialLocal utilization of natural gas in areas without central pipeline connection.Gas from local reservoirs, pipeline, landfills, flare, gas wells or coal mines.Sizes from 1 – 50 tons LNG per day.Patented - LNG plant, licenced by SINTEF
13LNG transport Traditional propulsion system in LNG carriers LNG carriers built in the 1970s used boil-off gas from the cargo as fuel in turbine propulsion systems. The consequences were:Expensive fuel and reduced payloadHigher CO2 emissionsLow efficiency of turbinesLack of crew with turbine qualificationsExisting turbine design is at a limit to provide the power required by new large LNG carriersOption: Use other type of propulsion and return boil-off gas to the tank in liquid state.Re-liquefaction!

20Global environmental challenge Flare gasAssociated gas production can create a problem.If there are no infrastructure/pipelines, gas is either flared or regulations are such that oil cannot be recovered without gas solution.Alternatives are to liquify all the gas or to produce power from the light hydrocarbons and liquefy the heavier hydrocarbons, then store the liquid onboard for export:Hamworthy solutions based on our LNG, LPG or VOC technology!
