<p>AN IMPROVED METHOD AND PROCESS OF HYDROGENATION OF OILS, FATS AND FATTY ACIDS IS DISCLOSED. IT COMPRISES THE STEPS OF HEATING AND DRYING OF FEED STOCK, HYDROGENATION, COOLING BY HEAT RECOVERY, IN A SINGLE VERTICAL SELF STANDING COLUMN (20) WITH MULTIPLE COMPARTMENTS ARRANGED ONE OVER THE OTHER FOR GRAVITY FLOW. THE HYDROGENATION PROCESS OCCURS AT HIGH PRESSURE WITHOUT AN AGITATOR AND NEAR ZERO HEAT INPUT FOLLOWED BY THE FILTRATION OF CATALYST, POST BLEACHING AND FINAL HEAT RECOVERY. THE INVENTION DISCLOSES SEVERAL IMPROVEMENTS IN THE METHOD AND APPARATUS.</p> |
