diesel and 1-7.6% for gasoline) mixed with air • Ignition temperature: 281-343ºC (538-649°F)
Estimated Greenhouse Gas (GHG) Reduction in Light-Duty Vehicles (LDVs)
• LNG (21-25%, CH4)• CNG (21-26%, CH4)• Natural gas vehicles reduce emissions

L/CNG Station Operations
L/CNG Station Operations
• Fuel is brought in by transport trailers• LNG is stored in a cryogenic tank• Vehicles are fueled using a pump and single fill hose
from dispenser
CNG Station Operations
• Fuel is supplied via local pipeline• Gas is compressed and stored in ASME tubes/bottles• Vehicles are fueled by pressure differential from the
storage banks / compressor
L/CNG stations are designed to refuel using low-pressure (“slow-fill”) or high-pressure (“fast-fill”) systems.

Cryoquip, Inc. is an industry leader in the engineering and manufacturing of a diversified line of LNG vaporizing systems which use natural gas, ambient air, water, or steam as an energy source. The systems are designed for either stationary single site applications or as portable systems to be transported from site to site on available trailer or other mobile methods. Applications include ‘send out’ vaporization systems for peak shaving plants, temporary gas pipeline supply in the event of emergency or scheduled shutdowns, vessel pressure building, or other process applications for either continuous or temporary service. Cryoquip also manufactures modular, skid-mounted nitrogen cycle LNG liquefaction plants as wells as expander plants for LNG production using pipeline pressure-let-down, LNG boil-off recovery systems, and nitrogen rejection units.

Energent Corporation was formed at the start of the 21st century to create a new paradigm for energy production. By exploiting waste heat and pressure, Energent is developing efficient and cost effective means to convert lost energy into useful power for liquefaction and air separation plants.
When installed in parallel with a two-phase J-T valve, Energent’s Flashing Liquid Expander (FLE) generates electricity, increases liquid production, and reduces the specific power required for refrigeration. The FLE, also known as a Variable Phase Turbine (VPT), combines converging-diverging nozzles with an axial impulse turbine to recover energy from supercritical, flashing liquid, vapor, and liquid expansions. Synchronous speeds eliminate the need for a gearbox and the FLE’s hermetic system requires no shaft seal. Unlike radial inflow designs, Energent’s axial impulse turbine prevents erosion from the two-phase flow, requires only a single stage, and achieves high efficiency with flashing LNG.
