Abstract
The present disclosure is related to an apparatus and method for purification of biological feedstock, such as reducing or removing nitrogen containing compounds therein. The method can include subjecting the feedstock to a first separation step for obtaining a first fraction containing free fatty acids and nitrogen containing compounds, and collecting the residue containing acylglycerols. The first fraction is reacted with glycerol to obtain acylglycerols from the free fatty acid therein. This fraction is subjected to a second separation step for obtaining a second fraction containing nitrogen containing compounds, which is discharged as waste-product. The remains from the second separation contain formed acylglycerols and are collected.
