【Abstract】 The technology of refining linolenic acid by wiped film molecular distillation is studied in this paper. The effect of the operating parameters, such as: the evaporation temperature, the system pressure, the feed flow rate, and the feed temperature have been studied. All of these parameters have some effects on the purity and yield of linolenic acid. The appropriate process conditions are obtained through this study.更多还原
