Abstract:
1. A system for reducing a pressure of a gas, comprising: a first regulator valve; a vortex regulator connected to the first regulator valve, the vortex regulator comprising a vortex tube and having at least one inlet to receive natural gas and at least one outlet for releasing the natural gas at a substantially decreased pressure and temperature; a first heat exchange device configured to receive the natural gas from the vortex regulator and to increase the temperature of the natural gas; a second regulator valve, the second regulator valve comprising a pressure-reducing regulator in fluid communication with the first heat exchange device and configured for further reducing the pressure of the natural gas and communication with the natural gas; a second heat exchange device configured to receive the natural gas from the second regulator valve and to increase the temperature of the natural gas; and a bypass line connected upstream of the vortex regulator and downstream of the vortex regulator to allow natural gas to bypass the vortex regulator.
