Case study
Requirement
Compressed hydrocarbon (HC) gas is
commonly used on offshore oilrigs to
control instruments when compressed
air is not available for use. However,
moisture, particles or oil in the gas can
damage downstream equipment and cause
malfunctions that make it difficult to control
the process efficiently. The Malaysian oil
and gas company PETRONAS required a
filtration system that could effectively clean
and condition the gas for safe use with the
valves that control pumping operations.
The system had to be durable enough to
stand up to the contaminants common in
HC gas as well as to withstand the harsh
marine operating environment. It also had
to be long lasting to accommodate the long
maintenance cycles of unmanned satellite
platforms.
Solution
The IMI Norgren F22 stainless steel filter was
already proven to withstand the corrosive
salt-spray environment. For this application,
Norgren (now IMI Precision Engineering)
modified it with a unique new convoluted filter
element that allows high flow with minimal
pressure drop. A three-stage filtration system
uses two general-purpose filters to remove
particles of 25 microns and 5 microns. The
third stage is the new IMI Norgren F22H,
which removes water, particles down to 0.01
micron and oil to 0.01 ppm. The new filtration
system fit the original equipment footprint,
simplifying installation. The larger filter and an
optional automatic drain extend maintenance
cycles.
Coalescing filter prolongs equipment
life on unmanned offshore drill rigs
