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

7. CNG for Industrial Gas – Why?
 Low Cost

8. CNG for Industrial Gas – Why?
Low
Environmental
Impact

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

10. NGVs and Conventional CNG demand

11. Industrial Gas

12. End Users
Power Plants – Mining - Metals Production - Pulp and Paper - Asphalt
Production - Food Processing - Fracking Units - Drill Rigs

13. Main Components

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

25. Case Studies

26. Urumqi, China
 Large central mother station in
Urumqi
 Many daughter compressor
stations nearby to fill vehicles

27. Cavendish Farms - Canada
 140km round trip
 11 Type 1 tube trailers

annually
 Flow capacity: 5,600 scfm

28. Mexico
 Type 4 trailers, ~160 km round trip
 Provides fuel for Modelo (Corona)
Factory
 Flow capacity: 16,000 Sm3/h
