Nitrogen Services:
Liquid N2

Reduce plant and pipeline downtime,
optimize crucial shutdown periods

Applications• Hot N2• Drying

Nitrogen (N2) at high flow rates,pressures and temperatures cansubstantially reduce plant andpipeline downtime by providing
efficient purging/blanketing, drying,pressure testing and productdisplacement solutions in a safe,
inert manner.
The Baker Hughes Process & Pipeline
Services (PPS) N2 services fleet isfully mobile and independent ofclient-support facilities. PPS provides
N2 where plant supplies may beinsufficient for applications such as
purging, displacing large-diameter
pipelines, high-velocity cleaning andpigging runs, accelerated cooldowns,
and pressure testing.
PPS provides high-flow N2 at a wide
range of pressures and temperatures
to ensure the safe start-up or
shutdown of all systems.
PPS personnel remain on call 24hours a day, seven days a week.
Also available around the clock is
a diversified fleet of self-contained,
nitrogen-pumping equipment used
to provide the most efficient N2solutions, custom engineered foryour needs.

N2 services whenever andwherever needed
PPS has extensive experience

using N2 for all applications. Vast
technical knowledge facilitates thebest service technique for eachapplication. In addition, PPS ensures
optimal scheduling, connection
arrangements, and site services
required for the job.
PPS’ innovation and customization
makes it far more than a commoditysupplier. N2 projects are engineered
start-to-finish, typically completing
operations faster while using lessN2. We’re committed to providing
the right portable N2 supply andengineered services at the customer’schosen location. As N2 services
are often required on an urgentbasis, operations are organized torespond quickly with support from anunmatched array of service locations
worldwide.

Hot N2
Injected at controlled hightemperatures, it provides a safe, inert,
and controllable medium for catalyst
regeneration, furnace bake-outs, andhydrocarbon and solvent stripping.

DryingProvides an efficient, safe and inert
medium to extremely low dewpoints,providing a much higher capacity tocarry moisture than alternative gases.

• Purging and blanketing• Leak testing• Accelerated cooldowns• Pipeline product displacements• Foam inerting• Freeze plug isolations

Features and benefits• High flow rates – N2 pump units
that can deliver up to 16,000 scf/min (460 m3/min) with a singleunit.
• High pressures – N2 pump units
that can deliver pressures of up
to 10,000 psi (690 Barg).
• High temperatures – Direct
fired N2 pump units and steam
vaporizer units that can deliver
nitrogen gas at temperatures up
to 572°F (300°C).
• Supply options – Ability to source
liquid N2 from suppliers acrossthe country, minimizing costs andensuring nearby delivery points.
• Storage options – Large fleet ofN2 storage equipment, including
standard capacity and bodyload transports, as well as King
storage units that hold up to
23,000 gal of liquid N2.

Purging & Blanketing
Replaces hydrocarbon vapor, flammable and toxic gas, or
air with an environmentally safe and inert medium during
turnarounds, shutdowns, service changes, inspections andmaintenance.

Leak TestingN2 (with a trace of helium), used for final commissioning,
verifies the safety and environmental integrity of new andexisting facilities, accurately detecting leaks as small as
0.10 scf/year.

Accelerated Cooldowns
A controlled cooling agent can greatly reduce the timerequired before remedial work begins, reduce the risk of fire
and provide a safe, inert atmosphere.

Pipeline Product Displacements

revalidation testing, pigging and decommissioning areaccomplished quickly using , high flow rates and pressures.

Foam Inerting
Eliminates explosive atmospheres in systems where it is
not feasible to remove all hydrocarbons or flammableproducts, allowing hot cutting on systems still containing
flammable liquids.

Freeze Plug Isolations
Used as a temporary isolation tool to freeze water, gel,and some hydrocarbon products in various sized pipes.
It provides isolation anywhere in the system, particularly
where valves are not available.
The PPS turnkey approach maximizes the effectivenessof N2 applications and frees customers to focus on otherissues during crucial shutdown periods.
