“…Besides, methane (R50) and ethane (R170) are the main components in nature gas and both of them are important components of mixture refrigerants in mixture Joule-Thomson low temperature refrigerators (MJTR) [1], especially in the application area of cryogenic temperature zone. Many fundamental parameters, such as thermodynamic properties, as well as the heat and mass transfer coefficients, are crucial in designing and manufacturing cryogenic systems and Liquefied Natural Gas (LNG) facilities.…”
