David VanLaar, P. Eng, provides an overview of industrial gas applications, critical system components, and case studies. This will include in depth overview of key considerations for viable transportation and storage including cost
Bulk Gas Transportation systems have enabled customers worldwide to take advantage of the tremendous cost reduction and environmental benefits of converting to natural gas without waiting for expensive pipeline or LNG infrastructure. The PRS system is designed for pressure let down of natural gas delivered to a customer site by mobile storage. The PRS system is made up of two modules: Pressure Reduction Module (PRM) and Heating & Control Module (HCM).

6. Overview of Natural Gas and CNG
Compressed natural gas (CNG):
composed of approximately 95 percent methane
normally stored at 3,600 psi (250 bar) in specially
designed containers
stays in a gaseous form
typically compressed from a transmission or distribution
pipeline
30% lower cost than other fuels
30-40% fewer greenhouse gases during combustion than
other fuels
9. CNG for Industrial Gas – Why?
Safer
non-toxic, lighter-than-air and
disperses quickly
higher ignition temperature than
gasoline and diesel fuel
narrow flammability range and will
only burn when the ratio is between
5~15% mixed with air
CNG/NGV systems and storage
vessels are built to the highest
standards and have long and enviable
safety records worldwide
14. Pipeline – Gas Source
Typically transmission lines (300 psi / 20 bar – 1000
psi / 70 bar)
Higher pressure means less compression is required
– less energy consumption
Location of mother station is often flexible
Require gas with low water content or use gas dryer
Require natural gas with >90% methane
15. Compression – ‘Mother’ Station
Multiple compressors (500 to 3000 hp is typical)
Non-lube technology is important to ensure trailers
don’t fill up with oil
Electric or engine drive
Typical station equipment:
Compressors
Chillers
Fill Posts
16. Compression – ‘Mother’ Station
FullFill Technology ensures that
every bulk gas shipment is
completed quickly and filled as
completely as possible. IMW
systems ensure that transport
modules are filled at the optimum
temperature and gas density
through:
Integration of proprietary
compression technology and
comprehensive dispensing
architecture
PLC controlled continuous
thermal management
17. Transportation
Transportation is most significant cost driver of industrial gas
products
Trailers are made up of small or large cylinders in 4 types:
Type 1 – 100% steel (heaviest, smallest payload, $)
Type 2 – hoop wrapped steel
Type 3 – hoop wrapped aluminum
Type 4 – fully composite (lightest, largest payload, $$$)
Some vendors:
18. Decompression – ‘Daughter’ Station
Typical equipment:
Decanting Posts
Pressure Reducing Modules
Heating Control Modules
19. Decompression – ‘Daughter’ Station
Decanting Posts:
Hoses – usually multiple 1”
hoses without breakaways
Emergency shut off valves
(manual and automatic)
Temperature and pressure
measurement
Low temperature
construction
Over pressure protection
20. Decompression – ‘Daughter’ Station
Pressure Reducing Module:
Emergency Shut Off
valves
Heat exchanger modules
to heat gas
2 stages of pressure
regulation
Overpressure protection
after both stages of
pressure regulation
Optional metering
21. Decompression – ‘Daughter’ Station
Heating Control Module:
Provides heat for PRM
heat exchangers
Includes pumps and water
control valves
Includes PLC and
electrical cabinet
22. Decompression – ‘Daughter’ Station
Other Developments:
All in one PRS units for
International Customer
Mobile PRS for portable
applications
Large custom units for
specific applications
23. Decompression – ‘Daughter’ Station
Maximum Offload Capacity
ensures that only a minimal
amount of gas is left on the
trailer before it is disconnected.
This is achieved by:
Using two line unloading
methodologies where
possible
Designing systems for
minimal pressure drop
Employing scavenging
compression where
necessary to remove
remaining gas
24. Decompression – ‘Daughter’ Station
Proven Scalability to
provide standard product to
custom applications with
current systems installed
with capacity of up to 14,000
Nm3/h.
Provides
redundancy, reliability and
quality.
Can easily add more units
if demand increases, or
remove equipment and
move to several smaller
sites once gas pipeline
arrives
28. Mexico
