Delivering Cost Effective Natural Gas to Your Remote Facility April 24, 2014

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 Full. Fill 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 Nm 3/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

Cavendish Farms - Canada § § 140 km round trip § Flow capacity: 5, 600 scfm 11 Type 1 tube trailers Remote, food processing plant Offsets 22 M liters of heavy fuel annually

Mexico § Type 4 trailers, ~160 km round trip § Provides fuel for Modelo (Corona) Factory § Flow capacity: 16, 000 Sm 3/h

Australia § Type 3 trailers, ~600 km round trip § Provides fuel for 100 MW power plant § Flow capacity: 13, 000 Nm 3/h
