2. About IMW
IMW has been manufacturing industrial machinery since 1912, and has evolved to be a leading
manufacturer of natural gas compression systems, serving all major markets Globally. Equipment
is currently operating mid-east to North of the Arctic Circle.
• Quality Products & Leader in CNG Compression
• Non-Lubricated Compression for Clean CNG
A variety of configurations for all applications
3. A Clean Energy Company
IMW operates as a wholly owned subsidiary of Clean Energy Fuels Corp. (NASDAQ: CLNE).
Clean Energy is the largest provider of natural gas fuel for transportation in North America and a
global leader in the expanding natural gas vehicle market.

8. Why?
Use local, domestic energy
Save 20 – 30% of energy costs
Clean energy solution – lower emissions
Virtual Pipelines for Remote Energy Systems
12. Seek a high inlet gas pressure for mother stations to
reduce energy consumption and operating costs.
‘Mother’ Station Pipeline Pressure
Example: 1000 SCFM (1600 Sm3/h) compressed to 4500 psig (310 barg)
At 0.12 USD per kWh and 5000 run hours a year, electricity cost
savings of $115,000 USD per year can be expected!
Maintenance costs are also substantially reduced because less
equipment is operating.
Scenario 2: transmission pipeline
Inlet pressure of 1000 psi (70 barg)
150 hp (110 kW) required
Scenario 1: distribution pipeline
Inlet pressure of 100 psi (7 barg)
400 hp (300 kW) required

Temperature Management
• Virtual Pipeline operates by changing the gas volume (CNG)
• Gas pressure and temperature are functions of gas volume and
therefore need to be managed
16. ‘Mother’ Station Gas Composition
Methane
Ethane
Propane
Butane
•80%
•10%
•5%
•5%
• Attention needs to be paid to gas composition due to temperature
fluctuations
• Water content
• Gas dryers should be used if water content is higher than 2 lb /
MMSCF (32 mg/m^3)
• Methane content
• Natural gas mixtures with less than 90% methane need to be
evaluated to ensure heavy hydrocarbons don’t drop out as liquids
17. Problems with oil:
• Compressor discharge gas is typically
10C above ambient
• Even good coalescing filters don’t
remove oil well at warm temperatures
– oil stays as a vapor
• When temperatures reduce oil vapor
turns to oil liquid
• Trailers collect oil and lose capacity
• PRS systems also collect oil where
ever gas velocities or gas
temperatures decrease
• Oil buildup increase maintenance
costs and downtimes
‘Mother’ Station Compressor Lubrication
Non-lubricated
compressors
ensure that oil
doesn’t enter
the gas stream!
18. 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
19. 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:
Proper prediction of trailer filling
temperature rise
Proper sizing of cooling equipment
Integration of proprietary compression
technology and comprehensive
dispensing algorithms
PLC controlled continuous thermal
management
Compression – ‘Mother’ Station
20. 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
21. End Users often have critical applications – consider:
1. Redundant compressors – can daily trailer
requirement be filled at the lowest pipeline pressure with
one compressor down for maintenance?
2. Trailers – is logistics modelling conservative? What
happens if a trailer blows a tire?
3. PRS units – can PRS units handle peak loads even if one
unit is offline?
4. Storage at daughter side – install ground storage and
booster compressor if transportation link between mother
and daughter can be interrupted
Redundancy
24. IPP – Gas Turbines
Gas Turbines typically require:
1. High inlet pressures – 25 to 50 barg
2. Warm gas well above dew point
3. Wide range of flow rates
4. Less than 1 second shut down times
Gas Turbines typically are:
1. Sensitive to pressure pulsations in
certain frequencies
2. Sensitive to even small amounts of
oil carryover
3. Sensitive to heavy hydrocarbons
and any liquids
GE LM6000
25. Peaking Power Plants
• Power plants
sized to turn on
for peak loads
only.
• Often don’t
have a gas
pipeline nearby
or don’t have a
properly sized
gas pipeline
nearby

27. Asphalt Plants
• 4000 asphalt mixing facilities in the US
alone
• Plants consume between 200,000 to
600,000 gallons of fuel oil per year.
• Facilities are located close to the paving
projects they work on and therefore they
cannot always be built near a natural gas
pipeline
• Cost savings over #2, #6 or bunker oil is
20 – 40%
• CO2 and particulate emissions reduction
• Burner conversion costs range from $100K
to $300K
• Payback of about 1 year

29. Drill Rigs
Where suitable natural gas isn’t
available, drilling rigs are run on
diesel.
Incorporating CNG into drilling
rigs typically:
• requires a $200,000 investment
for conversion kits
• Provides the same power
output as diesel
• Provides cost savings of about
$1000 per day
• Reduces CO2 and particulate
emissions
30. Stranded Distribution Networks
Remote towns with no
access to natural gas can be
served by virtual pipelines.
Daughter station is built in a
central location and
distribution pipelines are built
to nearby factories or housing
complexes.
Uptime is critical so typically
dedicated ground storage is
utilized to provide backup gas
if the trailer traffic is
interrupted.
33. Inputs Required
Technical Inputs:
1. Current or Predicted Fuel Type Consumption – per year
a. Peak load and minimum load if available
2. Regional location of mother and daughter site
3. Natural gas supply pressure at mother station
4. Natural gas delivery pressure at daughter station
5. Gas composition at mother station (water content, methane content)
6. Fuel end use uptime required and necessary redundancy
7. Trailer type (if known)
8. Distance between mother and daughter station and average travel speed
Commercial Inputs:
1. Cost of natural gas from pipeline or cost of CNG from provider
2. Cost of current fuel
3. Transport operating costs for local region (if available)
4. Electricity cost
