| Abstract: | The shortages of supercritical fluid extraction equipment using in China were analyzed, and the improvement was made and designed out a set of bench scale supercritical extraction equipment that was suitable to use the medium of carbon dioxide. The results of trial more than 34 000 h showed that it was easy to use, operation safe, sealed reliable and fulfilled request of several materials. In general, the function of equipment was as good as that of the imported one, mean while, it is cheaper with its own advantages of superior. |
