SCFE(supercritical fluid extraction) is a new chemical separation technology. After the last 30 years development, the SCFE technology already became an energy-saving chemical separation method, which has caused more and more researchers’widespread attention in the world. Whether in basic theory research or application, this technology has all made many progress, but because people's study is not still enough on phase equilibrium in the SCFE process and the transmission fundamental, many difficult...
