At Wärtsilä we strive constantly to do what is best for you. This includes optimising the lifecycle

value of your installations by offering precisely what you need; a promise we can deliver on

since we provide the oil & gas industry with a broad portfolio of integrated solutions, products

and global services.

Whatever the location, no matter how harsh the conditions, we deliver world class

efficiency, fuel flexibility, and environmentally sound solutions – everyday. This is why today, we

are involved in bringing more than 6 percent of the world’s total oil production to the market.

volume by a factor of around 600, enabling

efficient transport to end-users overseas as well

as on land where pipelines are not a suitable

sustainable solution. Small scale liquefaction

plants are one of the important parts in the LNG

chain, making a growing LNG market possible.

Renewable fuels are attractive on the world

market due to environmental targets and also

the aim to reduce the dependency of fossil fuels.Biogas is regarded as one of the most important

sources to achieve these targets – to meet

this market Wärtsilä has developed solutions

especially designed for biogas liquefaction.

Natural gas has become one of the most

important energy sources in the world, and

the consumption worldwide is believed to

grow in the coming decades. It is now an

alternative fuel in marine applications, power

generation plants and most recently in

vehicles. The replacement of fossil fuels such

as HFO, MDO and diesel has a significant

positive contribution to the environment –almost eliminating emissions of NO

Wärtsilä is following the best-available-

technology (BAT) principle regardless of

capacity or refrigeration technology. This

ensures maximum operating ability, ease of

operation and low energy consumption for our

clients, irrespective of plant capacity.

Wärtsilä’s highly qualified engineers have

TECHNOLOGY PHILOSOPHY

LIQUEFACTIONPROCESS – MODULEBASED SOLUTION

Large variety of gas sources, both in gas

quality and quantity, require a variety of

liquefaction systems.

Wärtsilä’s solution to this is a module

based design, where every module is

optimized for the process it was intended for.

In this modern age of industrial competition,

a successful plant design should be able to

sustain the changing trends in demand and

still produce optimal economic gains.

The schematic diagram (right) shows

the different types of modules that could be

delivered in a liquefaction plant supplied by

Wärtsilä.

developed a product portfolio adapted to

the needs for mini, small and medium sized

LNG/LBG production plants. A modularized

approach is selected, where customers can

easily select a scope of supply from Wärtsilä

adjusted to their specific project need.

Wärtsilä have developed the energy

efficient Mixed Refrigerant (MR) liquefaction

technology for even lower capacities than our

usual small and mid-scale LNG plants. The

choice of technology in combination with ourfast track engineering model results in low

ADVANTAGES OF MIXED REFRIGERANT:

• Low power consumption – reducing OPEX.

• All components are conventional and

robust technology – reducing CAPEX.

• Designed for unmanned operation.

• Local control of LNG export. Truck driver

can load on his own.

• Robust main rotating machinery with high

efficiency – oil flooded screw compressor.

• Simple energy supply, only electric power

needed.• Easy start up and shut down of all

systems.

• Standard capacities: 10, 17 and 25 ton

LBG/day.

• Short delivery time.

• Easy shipment.

• Plug and play philosophy, skid based –

Relocation possible.

• Broad range of applications biogas,

pipeline gas, CBM and flare gas.

• Biogas liquefaction

• Biogas from household organic waste

in Oslo region

• Biogas to be used on city buses

The liquefier system uses a mixed

refrigerant technology, where one single MR

compressor and one aluminum plate-fin heatexchanger (PFX) are the main components

in the system. A standard glycol chiller

(pre-cooling unit) is incorporated to improve

energy efficiency and to ensure stable

operation of the MR process.

Wärtsilä’s larger liquefaction plants are

based on the reversed Brayton nitrogen

refrigeration cycle. Nitrogen is the sole

refrigeration medium, and used in a process

of compressing and expanding the nitrogen toobtain the required cryogenic temperature.

ADVANTAGES OF BRAYTON NITROGEN

REFRIGERATION CYCLE:

• Low power consumption – reducing OPEX

• Robust, reliable and simple to operate

technology.

• Capacity control is very easy and quick.

• Designed for unmanned operation.

• Easy start up and shut down of all systems.

• Local control of LNG export. Truck driver can

load on his own.

• Simple energy supply, only electric powerneeded.

• Refrigerant will be produced directly from

air on site – No logistics connected to the

refrigerant.

• There is no required handling of chemicals.

• Our design provides a ZERO FLARE solution.

During normal operations, hydro-carbon

losses will be zero.

Wärtsilä delivered its rst onshore LNG

production facility in early 2003, to Gasnor

in Snurrevarden, Norway.

For over ten years northern Europe’s

rst free-standing small-scale LNG

production facility has demonstrated the

potential of Wärtsilä onshore liquefaction

technology.

The Snurrevarden LNG productionplant is based on the Brayton nitrogen

cycle, which combines simplicity

and robustness, enabling unmanned

operation.

The Kollsnes plant went into operation in

2007 with a capacity of 84,000 tons per

year. Storage capacity is 4,000m3 and

the gas export facilities include two truck

lling stations and an existing loading jetty

for small LNG carriers.

These liquefaction plants are easy to operate,

reliable, fully automated and represent a low

life cycle cost solution in the small to medium

size liquefaction capacity range.

Small scale liquefaction plants open newmarket opportunities to develop local or

regional gas distribution networks, where

gases as an environmentally friendly and

competitive energy source did not previous

exist as an alternative.
