Abstract:
The present invention relates to a process for in situ regeneration of spent filter aid including the steps of: a) circulating through a spent filter aid cake in a circulation loop a regenerating oil at a temperature of from 40° C. to 100° C., in a regenerating oil/spent filter aid (v/w) ratio of from 0.3/1 to 12/1; b) removing the regenerating oil from the treated spent filter aid cake; and c) recovering the regenerated filter aid.
