Despite its reliability, it has been put to few practical uses. In this study, a new practical application has been proposed to take advantage of the vortex tube. The idea is to put the vortex tube in a natural gas pressure reduction system and take advantage of the cooling capacity. For this purpose, an experimental study has been carried out to investigate thermal behavior of natural gas as it passes through a vortex tube. In addition, the effects of the hot tube length on the vortex tube thermal separation behavior have been studied. A comparison has been made between air and natural gas as they pass through the vortex tube. %8 2012-02-02
