| titleOfInvention | Process for obtaining fatty acid lower alkyl esters from unrefined fats and oils |
| abstract | Suggested is a process for obtaining fatty acid C 1 -C 4 alkyl esters from unrefined fats and oils, which is characterised in that: n(a) unrefined fats or oils having an acid value of from 1 to 20 are treated with hot steam in a counter-current column to provide a first fraction of free fatty acids and low boiling impurities at the top and a second fraction of de-acidified and de-watered fats or oils at the bottom of the column; n(b) said first fraction is subjected to acidic or enzymatic esterification with a lower C 1 -C 4 alcohols in order to provide a third fraction of fatty acid C 1 -C 4 alkyl esters; n(c) said second and said third fraction are combined and subjected to a low pressure transesterification in order to provide an intermediate fraction of fatty acid C 1 -C 4 alkyl esters, C 1 -C 4 alcohols and glycerol; and n(d) said intermediate is subjected to a separation process in order to remove C 1 -C 4 alcohols and the glycerol in order to provide a second fraction of C 1 -C 4 alkyl esters. |
