used for a given application the pressure of the cryogenic liquid phase gas entering the nozzle may be in the range of 5 000 to 40 000 psig and the temperature may be in the range of u2212 205 u00b0 to u2212 25 u00b0 c u2212 320 u00b0 to u2212 15 u00b0 f it will be appreciated that there may be additional distribution components such as pumps and heat exchangers piping and valves nozzles and ancillary equipment known to persons skilled in the technology in one embodiment the equipment may include one or more nozzles each comprised of two or more nozzle outlets oriented in separate directions in one embodiment two nozzle outlets have parallel axis of orientation but with each outlet directed in an opposite direction each nozzle may rotate on an axis at speeds greater than 2100 miles per hour the nozzle may also move forward and back on the nozzle axis of rotation an example of this type of a nozzle is described in u s pat no 5 706 842 issued to raoul caimi et al and which is incorporated by reference herein the invention benefits from the liquid phase traveling from the nozzle at the stated speed in order to achieve an adequate liquid mass flow rate needed to create the thermal shock achieving this speed is facilitated by the pressure levels of.
