PROCESS OF OIL RECOVERY AND REGENERATION OF ADSORPTIVE PROPERTIES FOR SPENT BLEACHING EARTH

摘要

THE PRESENT INVENTION RELATES TO A PROCESS FOR THE REGENERATION OF ADSORPTIVE PROPERTIES FOR SPENT BLEACHING EARTH THAT COULD BE REUSE AS AN ADSORBENT. THE PROCESS ENABLES THE RECOVERY OF OIL THAT IS RETAINED IN THE SPENT EARTH. AND PROVIDES AN ADSORBENT -WHICH HAS ESSENTIALLY RETAINED MOST OF ITS ADSORPTIVE PROPERTIES THROUGH CAREFUL CONTROLLED CONDITIONS OF REACTIVATION PROCEDURE. THE ENHANCED ADSORBENT FROM THE SPENT EARTH IS REGENERATED BY SOLVENT EXTRACTION AND HEAT TREATMENT BY FURNACE AT SUITABLE TEMPERATURES. THIS FURTHER HELPS IN SOLVING THE WASTE DISPOSAL PROBLEM BY REUTILIZATION OF THE SPENT BLEACHING EARTH.
