The FSP System:
Readily available, less expensive feedstocks contain a significant amount of Free Fatty Acids (FFA). These FFA’s must be removed prior to the transesterification process, as they will form soap through an alkali catalyst during transesterification. Traditionally, FFA found in biodiesel feedstocks is converted into Fatty Acid Methyl Ester (FAME) through Esterification with Methanol and using Sulfuric Acid (H2O4) as a catalyst. Reaching >2% FFA is easily achieved through Acid Esterification. SRS’ FSP System for Acid Esterification pretreatment enables new and existing plants the ability to incorporate multiple high FFA feedstocks.
