| Abstract: | With the raw material of spent bleaching clay of castor oil refining,castor oil was recovered by 6# solvent extraction with special equipment designed and manufactured by oneself.The effect of the temperature and the solvent extraction times on the solvent extraction result were also discussed.This operating technology is very steady.Through reclamation,the quality of recovered castor oil has reached the ICOA-1# castor oil criterion.The residual castor oil in the spent bleaching clay is less than 5% after recovering castor oil. |
