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