delivering cost-effective natural gas to your remote facility – new innovations & cases for...
DESCRIPTION
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).TRANSCRIPT

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
CNG for Industrial Gas – Why?
Low Cost
CNG for Industrial Gas – Why?
Low Environmental
Impact
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
NGVs and Conventional CNG demand
Industrial Gas Concept
‘Mother’ Station
‘Daughter’ Station
End Users
Power Plants – Mining - Metals Production - Pulp and Paper - Asphalt Production - Food Processing - Fracking Units - Drill Rigs
Main Components
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
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
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
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:
Decompression – ‘Daughter’ Station
Typical equipment: Decanting Posts Pressure Reducing Modules Heating Control Modules
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
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
Decompression – ‘Daughter’ Station
Heating Control Module: Provides heat for PRM
heat exchangers Includes pumps and water
control valves Includes PLC and
electrical cabinet
Decompression – ‘Daughter’ Station
Other Developments: All in one PRS units for
International Customer Mobile PRS for portable
applications Large custom units for
specific applications
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
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
Case Studies
Urumqi, China
Large central mother station in Urumqi
Many daughter compressor stations nearby to fill vehicles
