VORTEX SELF-HEATING PRESSURE REGULATOR:
Universal Vortex offers proprietary technology to eliminate t he need for Line Heaters or
Catalytic Heaters in pressure regulation where external heat is used for spot heating of the regulator’s pressure reducing orifice to prevent it from freezing in an expanding gas caused by the Joule-Thomson effect.
The Vortex Pressure Regulator (VPR) in the course of its performance reduces pressure of the inlet gas flow down to the desirable downstream pressure and simultaneously converts the
energy of a decompressed gas into a thermal flux (Vortex Phenomenon), forming vortex ‘cold’ and vortex ‘hot’ fractions. These fractions coexist in the low-pressure part of the VPR,
merge at the unit’s exit orifice and then are discharged into the downstream line. Prior to mixing up with the cold fraction, a
portion of the hot fraction is directed to the heat-exchanger set up on the unit’s pressure reducing orifice. Here the hot gas indirectly heats the orifice (spot heating) thus
preventing freezing of the depressurized gas flow.
The main benefits of the VPR are:
• Self-Heating device that needs no external heating
• Generates heat as an outcome of the routine gas pressure reduction
• Steady non-freeze performance regardless of the gas quality
• No moving parts
• No lost gas
• No maintenance
• Easy to install or retrofit in new or existing facilities
The VPR installation includes a monitoring valve upstream of the VPR for over
pressure protection of the downstream line at zero demand. The valve (usually a Fisher 627M) is connected with the line downstream of the VPR and has a set up point equal to the delivery pressure.
