<p>WHEN PRODUCING BIODIESEL FROM FATS, OILS, OR SPLIT FATTY ACIDS RICH IN STERYL GLYCOSIDES, THE LIGHT PHASE OBTAINED FROM TRANSESTERIFICATION OR ESTERIFICATION AND RICH IN FATTY ACID ALKYL ESTERS IS WASHED IN A WASHING COLUMN, WHEREIN THE SUSPENSION LAYER THAT FORMS IS TREATED BY STIRRING. THE STERYL GLYCOSIDES ARE THEREBY DISPOSED OF IN THE LIGHT PHASE OF THE WASH. IN A SUBSEQUENT TREATMENT OF THE LIGHT WASHER PHASE IN AN INTENSIVE MIXER WITH WATER, COMPACT STERYL GLYCOSIDE/FATTY ACID ALKYL ESTER/WATER AGGLOMERATES ARE OBTAINED THAT CAN BE EASILY PRECIPITATED BY MEANS OF CENTRIFUGATION. AFTER FURTHER PREPARATION BY DRYING AND/OR FILTRATION, BIODIESEL COMPLYING WITH SPECIFICATIONS IS OBTAINED FROM THE LIGHT PHASE OF CENTRIFUGATION. THE METHOD IS SUITABLE FOR PROCESSING FATS, OILS, OR SPLIT FATTY ACIDS HAVING A HIGH STERYL GLYCOSIDE CONTENT, AND AVOIDS THE USE OF ADDITIVES EXTERNAL TO THE PROCESS. THE METHOD IS CHARACTERIZED BY SIMPLE APPARATUS AND LOW ENERGY CONSUMPTION. THE MOST ILLUSTRATIVE DRAWING ACCOMPANYING THE ABSTRACT:</p> |
