We are “A Thermal Solution”
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.

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
No open flame, no electric heaters
No gas overheat possibility

Patented Self-Heating Single-Flow Vortex Pressure Reducer (VPR)
◦ 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
◦ Thermodynamically more efficient than two-way vortex◦ 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

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

◦ 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

◦ Exit gas temperature is equal to the inlet temperature, less the Joule-Thomson temperature drop– very cold!
