Compressor Station Emissions Reduction

COMPRESSOR
STATION EMISSIONS
REDUCTION
OUR SOLUTIONS
Due to recent EPA rulings, many natural gas
transmission compressor station operators have
recognized the need to enhance their assets to reduce
emissions. Companies have weighed the cost of
purchasing and installing new units against upgrading
existing facilities. At times, these companies have found
it more economical and less time consuming to perform
the upgrades.
EN Engineering has extensive experience with
compressor stations, including the design and
coordination of the installation of emission reduction
systems, as well as the associated facility modifications.
Clean Burn of Reciprocating Units
EN Engineering’s team of compressor experts
coordinate with equipment vendors to perform the on
skid upgrades. The units typically require upgrades to
turbo systems, reducing the amount of emissions in the
exhaust stream. Modifications to these units include:
• Upgraded oil and water cooling systems
• New intake and exhaust stacks and foundation
support systems
• Enhanced fuel gas systems with ultrasonic metering

Selective Catalytic Reduction (SCR)
Our engineering professionals have completed a
number of projects, including the installation of various
SCR systems on legacy turbine-centrifugal packages.
These systems utilize various forms of ammonia
injection to reduce exhaust stream emissions. EN
Engineering design services encompass
the installation of components for the SCR systems
associated with the existing unit, such as:
• Ammonia tanks, loading and unloading skids,
pumps skids, buildings, and detection systems
• Ammonia vaporizer skids including metering, safety
facilities, power and control
• Integration of system control and monitoring,
including Continuous Emissions Monitoring Systems
(CEMS), with existing station control system and
gas control facility monitoring
Dry Seal Gas Conversions
EPA rulings have dictated that existing wet seal system
emissions on centrifugal packages be reduced by
95 percent. Typically, flaring and reprocessing of the
fugitive emissions is less advantageous than installing
a dry seal gas system. Our experienced engineering
professionals have completed numerous conversions
with the installation of new dry gas seal panels, electric
and pneumatic booster pumps, and integration of new
and existing seal transmitters into the unit and station
control systems.
Auxiliary System Analysis and
Modifications
EN Engineering will complete all necessary upgrades
and modification designs related to associated auxiliary
systems affected by the emissions reduction efforts.
• Air system upgrades, new air compressor
packages, dryers, reservoirs, control, and
sequencing
• Cooling water and oil upgrades via cooler additions,
pump systems, control and power systems
• Fuel gas system upgrades with metering,
regulation, and heating
