Making CNG Cheaper and “Greener”Improving CNG Tank Filling Efficiency/Capacity &
Eliminating Gas Preheating in the CNG Decompression Process
Eliminate gas preheat in pressure reduction◦ Non-freeze pressure reduction of non-preheated gas
◦ No moving parts
◦ No external energy
◦ No Magic, Only Physics– Vortex phenomenon “discovered/invented” in 1931 by Georges Ranque, improved in 1947 by Rudolf Hilsch in a two-way (hot/cold) vortex tube cyclone
But we are different.
Confidential and Proprietary
2-way Vortex Tube
Problem: Conventional VT freezes up with natural gas due to Joule-Thomson, so conventional VT not commercially applicable
Patented UVI VT overcomes the conventional VT flaw with a non-freeze provision.

Gas Compression/ Mother Station◦ Reduce the impact of the heat of compression
◦ Eliminate costly glycol chilling loops
◦ Decrease the impact of logistical costs facing CNG transport
◦ Improve reliability and consistency of compression/filling process
Gas Decompression/ Pressure Letdown/ Daughter Station ◦ Every m3 of Gas in the tanks should be delivered to the customer
◦ CNG decompression should be affordable from a CAPEX and OPEX perspective
◦ CNG should be the cleanest, most fuel efficient energy solution for off-grid consumers
◦ CNG decompression should be simple and require NO external man-made energy
◦ Enable CNG companies to capture small consumers of gas when OPEX of conventional methods of decompression make the model unviable
◦ Eliminate Carbon Emissions from the CNG decompression process

VPRS-CNG does what no other decompression technology does:◦ Completely Eliminates Gas Preheat/Conditioning during the decompression process, while
overcoming the J/T effect
No Boiler
No Electric Heater
No Water Bath Heater
◦ Completely Eliminates CO2 Emissions
No consumption of gas product to feed a heater
No emissions from heater
No gas loss- closed loop decompression
◦ Reduces pressure from any inlet pressure to any outlet pressure
◦ No limitations on flow rate
◦ Modular PRS technology to increase operational flexibility
Fully Scalable-- Regardless of size of system, the design philosophy is the same
◦ Increased Reliability and Safety
No moving parts other than solenoid valves
Few wear items– all critical components static are Stainless Steel and Aluminum
A minimum of 0.6% of CNG flow is used as a fuel to preheat gas upstream of pressure reduction. For a sample flow rate of 5000Nm3/hr, this translates into the elimination of 61.3 kg/hr, or 536 tons/year of CO2 emissions!
Calculation: The chemical equation for burning methane: CH4 +2*O2 = CO2 +2* H2O. Therefore 1 kg-mole of CH4 corresponds to 1 kg-mole of CO2 Since 1 kg-mole of CH4 = 16kg and 1 kg-mole of CO2 = 44kg, then 1kg of burned CH4.generates 2.75 kg. of CO2
“Turn Key” Engineering/Procurement Solution◦ UVI to design and build entire bespoke decompression skid, including all accessories
◦ Deliver on on a FOB assembly shop basis
◦ Shipping/Installation by others with UVI instruction and support
◦ Delivery Timeframe: 16-24 weeks
Engineering Package & Core Technology & Equipment◦ UVI to design bespoke decompression skid for manufacture/construction/installation
by others
◦ UVI to provide drawing package, technology/IP license to build skid, and Vortex Pressure Reducers
◦ Start up support
◦ Delivery Timeframe: 8-10 weeks
Core Technology & Equipment◦ UVI to provide conceptual design and operating philosophy,
◦ High Pressure gas expands at the tangential inlet nozzle down to the delivery pressure
◦ Rotating low pressure gas in the Vortex Tube undergoes energy division, splitting into cold and hot fractions (Vortex Phenomenon)
◦ Hottest portion provides efficient internal “spot heating” of the inlet nozzle to eliminate freeze-up at the pressure drop point
◦ Cold and Hot flows are recombined prior at the pressure reducer outlet, negating the temperature delta
◦ Exit gas temperature is equal to the inlet temperature, less the Joule-Thomson temperature drop– very cold!
