Abstract: |
|||
| The invention relates to a refining process for coarse wool grease. The process features that a quaternary refining agent is used to replace the working procedures used in the existent technology, which includes impurity removal by centrifugal, acid adding, bleacher adding, dilution with organic solvent and organic solvent removal etc. After adding quaternary refining agent in the invented process, the impurities, free acid and pigments etc. can be removed once. The deposit promoter which can speed up the separation of impurities and water from wool grease, replaces the function of high speed centrifugal for reducing the quantity of washing water and of environment the pollution. | |||
