The document outlines the benefits and technological aspects of IMW Industries' virtual pipelines for delivering compressed natural gas (CNG) to remote facilities. It emphasizes the lower costs, environmental advantages, and safety features of CNG compared to traditional fuels, while detailing the systems and components involved in the transportation and decompression processes. Additionally, it highlights case studies demonstrating successful implementations of these CNG solutions in various industries and locations.

5. 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
Overview of Natural Gas and CNG

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

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

8. 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

9. NGVs and Conventional CNG Demand

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

11. Virtual Pipeline Concept
‘Mother’
Station
‘Daughter’
Station

12. Main Components

13.  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
Pipeline – Gas Source

14.  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
Compression – ‘Mother’ Station

15. 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
Compression – ‘Mother’ Station

16.  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:
Transportation

17.  Typical equipment:
 Decanting Posts
 Pressure Reducing Modules
 Heating Control Modules
Decompression – ‘Daughter’ Station

18.  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
Decompression – ‘Daughter’ Station

19. 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
Decompression – ‘Daughter’ Station

20. Heating Control Module:
 Provides heat for PRM heat
exchangers
 Includes pumps and water
control valves
 Includes PLC and electrical
cabinet
Decompression – ‘Daughter’ Station

21. Other Developments:
 All in one PRS units for
International Customer
 Mobile PRS for portable
applications
 Large custom units for
specific applications
Decompression – ‘Daughter’ Station

22. 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
Decompression – ‘Daughter’ Station

23. 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
