Abstract

Separation of methane and nitrogen from a mixture was investigated using a fixed geometry vortex tube. The inlet pressure was identified as the most dominant factor affecting separative power of a vortex tube of fixed geometry. Temperature separation was easily observed in a vortex tube, even by merely touching the hot and cold exits. The results show that there is a partial gas separation leading to a higher concentration of methane at one exit in comparison to the inlet and a lower concentration at the other exit.
