3Liquefied Natural Gas - An Introduction
LNG OVERVIEW
►LNG is Natural Gas reduced to liquid state by cooling it to –162ºC
►LNG is colorless, odorless, non-toxic and the gaseous form is lighter
than air
►Natural gas required to manufacture LNG – from gas reservoirs often
offshore
►Gas produced from two different kinds of reservoirs, each requiring a
different processing technique.
– Gas reservoirs – produced at High Pressure
– Oil reservoirs – oil-gas dispersion/mixed phase or oil reservoir
gas caps; relatively lower pressure

5Liquefied Natural Gas - An Introduction
Why should Natural Gas be liquefied?
►Liquefaction reduces gas volume by approx. 600 times.
►More economical for liquid transport
– through ship – between countries/continents
– through road carriers – in land.
►For remote gas fields (especially offshore) pipeline transportationof gas is expensive – hence natural gas is liquefied before
transportation

6Liquefied Natural Gas - An Introduction
WHY WE NEED LNG?
Growing power demand in the world and forecast
that by 2050 energy needs will double that of today –
gas is a cheaper source of fuel.Oil companies under pressure to reduce gas flaring
– develop strategies for dealing with gas.
Growing demand for cleaner fuels – gas is thepreferred choice for large-scale power plants.
Reservoir recovery – on an average about 60% of
the gas in the reservoir is recoverable, as comparedto 33% of an oil deposit.

8Liquefied Natural Gas - An Introduction
How is LNG/NG Measured?
►Natural Gas is measured in• Volume units, i.e. cubic feet or cubic meters
• Energy Units, i.e. Million BTU or Million kCalories
►VOLUME UNITS
• Supplies to Power plants measured in Million standard cubic feet/day (MMSCFD)
or Million standard cubic meter/day (MMSCMD).• Resources and reserves calculated in Trillions of standard cubic feet (Tcf).
A Gas field containing 3.65 TCF ≡ around 12 MMSCMD gas for 25 years
A rough way of visualizing a trillion cubic feet of gas ≡ imagine enough of
product to fill a cube with its sides two miles long►ENERGY VALUES
• Amount of energy obtained from the burning unit volume of Natural Gas measured inBritish Thermal Unit (BTU) or kCalorie or kJoule.
►
At sea level, it takes about 75 BTU (19 kCal) to make a cup of tea.►A cubic feet of natural gas gives off about 1050 BTU (depends on quality of
gas) » one cubic feet of Natural Gas may make 14 cups of tea
► 1 BTU = 0.252 kCalories = 1.055 kJoules

Simple configuration
Higher thermodynamic efficiency
Fewer items of machinery
Only one or two compressors for refrigerant compression

53Liquefied Natural Gas - An Introduction
LNG Vaporizers
LNG re-gasified in vaporizing units by heating,through heat exchange with seawater or byburning gas.
Open-Rack type LNG Vaporizer (ORV) uses seawater as the heat source.
Submerged Combustion Vaporizer (SCV) uses NG
as the heat sourceSCV used when ORV is under maintenance or for
peak shaving.
Multiple ORVs and only one SCV are used.
SCV capacity is generally 15 to 25% of ORVcapacity.

Open Rack Vaporizer
ORV composed of panel-shaped heat transfer tubesmade of aluminum alloy.
LNG flows upward inside the finned heat transfer tubes,sea water flows down along the outer surfaces of the
tubes. Performance Improvement and reduction of sea water
flow rate for conventional ORVs are limited due to iceformation on the outer surface of heat transfer tubes.
Approx. sea water requirement: 32 m3 /ton LNGevaporated at 5ºC T
To protect the ORV against corrosion by seawater, analuminum-zinc alloy is thermal-sprayed on the panels andupper and lower headers exposed to seawater.
