Gas Extraction• Millions of years ago. Small animals and plants in the sea form natural gas

and petroleum as we know and find it today.

• The following process occurs: a thick layer of (river) sand and clay

deposits on a layer of plankton.

• The high pressure and temperature of this thick layer turns plankton into

natural gas and petroleum.

• We often find the two together. On occasion, natural gas will penetrate

into other layers of the earth, as opposed to the much heaver petroleum.

In which case, they will be separated.

Gas Extraction• Natural gas coming directly from the source - both on land and at sea -

has a high temperature and is polluted with sand, water and oily

substances.

• Therefore, the gas first must be cooled and cleaned before running it

through pipes/lines.

• An air-cooled cooler brings the temperature of the gas down to

approximately 25°C and a gas/gas heat exchanger cools it further to -

15°C.

• Finally, using a Joule-Thompson valve, the temperature of the gas is

further reduced to -30°C, at which point all liquid and solid parts are

removed.

• The gas/gas heat exchanger then heats the cold gas again to well above

zero, transporting the now clean and dry gas via pipelines to the clients.

Challenge / question

Natural gas. Sand, water, oil. High pressure

and temperature. Cooling process: using

seawater, closed loop or outdoor air

• Some liquid components in the gas may

condense in the pipes.

• This can be prevented by cooling the gas

beforehand.

• Sometimes gas will have to be condensed,

where case cooling is key as it allows for the

most efficient condensation.

• If the gas has been transported through miles

of pipeline, it may be necessary to increase its

pressure (again).

• Compressors are used for this process,

however, each time the pressure increases,

cooling is required.

• Finally, cooling gas has its economic

advantages as higher temperatures demand

more expensive materials for the pipelines.

• Therefore, our clients need

reliable, sustainable/durable and safe coolers.

Our solution

• The pressure at the source of a newly

evaporated gas field can be very high.

• We develop and supply special, ultra-safe

and high pressure resistant coolers.

• As we have been involved in the

development and production of gas for

years, we have extensive, far-reaching and

often unique knowledge and experience in

this field.

• We are the first in the world to offer a

sophisticated subsea cooling process that

cools offshore gas under water using the

movement of the seawater.

• We also supply closed loop water cooling for

offshore gas and high pressure air-cooled

coolers for onshore gas.
